Piasini Engineering Info..

[456whpEvo8]

Hey whats up? This is my 4th posting in 2 years. I am just a forum reader. But it look like everyone is Confused on how to order or get info on the piasini flash and V3.

Here are some Examples with V3

Version 3 Piasini Flash Tune is done.

Key points are:
- Higher boost, and more consistent,
- Holds boost better,
- Throttle is held open,
- Power is more linear,
- Fueling is slightly leaner (very safe),
- TC issues are fixed. 1st and 2nd

Power till 7000 YaaaY


I will make it extremely simple for everyone and you don't even have to PM some random person you don't know (bang)

Piasini is based in Europe and Australia.

Here is there website

http://www.piasiniengineering.it

Here is the OZ mazda boards with all the data logs you need.

http://www.ozmazdaclub.com/forum/piasiniengineering/

The Interweb is my friend (first)

[Bravnik]

OZ ECU is DIFFERENT than ours, thus the results are NOT the same.

Piasini support in the US non existent. Until there are supporting documents in the US to support the tune, NOBODY will trust it. To date there are only a few out there, no dyno's that I would trust and none but one I know of has any mods to speak of. The only car I know that has any mods worth talking about reports lower PSI with the mods (16psi I think it was max).

I really wished this shit would ether die or provide some serious documentation to support it's claims in the US and on cars with full basic bolt-ons.

If you want to sell the Piasini tune in the US then by all means toss some flashes on cars for FREE. Pick a few people on each coast who are un-biased, give them the Flash for free and have them dyno and post results. If the results are good then the product will sell itself.

I also find it funny that the company that pushed the Paisini tune V3 (Top thread in OZ Forums) in your LINK is now OUT OF BUSINESS. Looking through the threads people with almost full bolt-ons are reporting 16psi max.

Dude there is simply NO WAY a single flash can LEARN your mods.

[Cue]

Honestly I think..... Oh wait.. Full House is on!! gotta go

[PCspeed3]

website only shows stuff for the regular mazda 3

[Cue]

Looking through the threads people with almost full bolt-ons are reporting 16psi max.

Look... the Cobb AP and the CP-E SB can do much better than 16psi. I'm not sure where you're getting your info.... Wait a sec, we talking bout the Piasini??.... I'm gonna go play with my hamster... he's so CUTE!!.. goojy wooji gaga... bebe booboo bahbah...

[456whpEvo8]

I am simply helping people that want the info out. If you want to argue or dis agree go right ahead.

[ForceFed]

Are you gone yet....?

[derspi]

I'm pretty sure if people wanted to they can find the info but thanks anyway. Unfortunately, not too many care to spend their hard earned money on a product that has little to no support when there are other options.

[456whpEvo8]

Are you gone yet....?

Nope, (hippy)

[tuckaloe]

This isn't quite "getting the word out". You were schooled on why the Pissonit tune isn't commercially viable for the US market and this is the best you can do?

Frankly, I want to like this tune. I have a thing for Italian performance. And no support is tragically and typically Italian. "It is the best in the world and you are a fool for having issues".

Give us something to work with that's applicable to our (no OZ) market.

[tuckaloe]

Can ANYONE out there address the legitimate and valid concerns being asked about here? Someone like SassiMac on the OZ forum would be a welcomed change.....

[MSMS3]

I think we all are waiting for an American MS3 with this tune with current (I mean recent) full dyno results and and complete data logging from someone we trust.

Maybe if a Piasini company rep would offer a reflashed ECU on loan to one of our respected members for objective side-by-side comparison testing, there could be some traction instead of just a lot of talk. We know what the AP and Standback tunes will and will not do.

What strains the credibility of the Piasini advocates to me is the claim of being able to get increasing power from our little K04 turbos at higher rpm's - above 6K, when we know there are serious thermal ineffeciency issues with that little turbo being able to push well up that high.

When dyno charts are produced showing the hp curve continuing to rise above 5500 rpm, mated with claims that the stock ECU is holding back power because the throttle is closing, red flags go up. This is especially true when we know that other tuners who have developed ways to get around the throttle position issue, still acknowledge that the engine falls flat after 5500 rpm.

I'd love to be wrong. Piasini guys, how about a loan of a Piasini tuned ECU to someone here with the interest in data logging and dynoing a before and after tune? After all, the Piasini is supposed to adjust to any bolt on's we may have, right? Sure would be a great way to quiet the skepticism and generate serious interest ($$$) in the the product.

[SuperStretch18]

Alright, well fuck you to.

Well played...

Fuck This Ghetto Shit..... If U Dont Like What It Is Then Shut Ur Mouth Fucking Cobb Sucker................

And this...

These two posts are exactly why people in the US will never appreciate the Piasini product. No evidence of anything offered from US vehicles and a dumb fucking attitude like if you don't take all the BS that the reps spew as fact, there is somehow something wrong with you.

After the last Piasini thread, I decided to refresh my research on this flash (I want that hour back) and it's honestly pretty baffling how the US market was handled. Things like people asking for dyno results and the rep responding "that's my cue to leave..." WTF is that about?

Regardless, the point is moot. The last thread like this clarified that the US rep is not doing mail-in flashes anymore, so unless you are local to Long Island or feel up for a road trip, it's not going to happen.

I am very interested in hearing about Cue's hamster though. That sonofabitch is cute!

[derspi]

After all, the Piasini is supposed to adjust to any bolt on's we may have, right?

I hope you know that this is just marketing banter right? This will never happen unless we start stuffing AI-level ECUs in our cars.

I like hamsters too...until they pee on your hand.

My comment was sarcasm. I thought that was understood. I don't believe anything coming from the Piss-in-it, oh, i meant Piasani people right now.

[yamomoto]

I can compare both tuning dumps from Piasini and from AP, place them in the editor on each other.
So tuning dump and stock dump.
Honestly speaking, I do not know, which there can attract attention?
Piasini has sharp, rough, torn tuning of engine. (eek2)
There are many errors in changes in the calibrations.
I express regret for the motors with such tuning from Piasini.
In AP everything is correct and, I would say, elegant.

I please to excuse for my English.

Interesting. So is the Piasani unsafe in your opinion, or just "rough around the edges"?

Here's why I ask. Back in the day, I owned a 2002 1.8t GTI. At the time, GAIC software was "rough" and aggressive, APR software was more refined. The rough stuff was actually alot more fun to drive. The APR was so smooth, made the same #s, but just didn't grab you and make you pay attention . So yeah, I'm kicking the door open for Piasani, if that's worth anything......

[yamomoto]

First, we speak about tuning firmware ecus Mazda.
You did see tuning dump from Piasini for Mazda?

For 1.8T GTI there are many finished, well developed versions.
Your version 1.8 GTI was developed directly Piasini :) , or in it they did purchase? :)

In the second place, I not the first year professionally deal with tuning firmware ecus, and this my personal opinion.

@ Yamomoto, I live in Switzerland and have a Piasini Tune on my 3 MPS. I dynoed my car after reflash, and I gained 55hp/100Nm with this tune/ETS and Test Pipe.
AP do NOT work on MPS!!!
I don't mind about what do you think about Piasini Tune, but I know it's another car with this. Now another guys in France use this reflash, and always the same gain about 40hp/100Nm (always dynoed before/after).

I'll change the downpipe and intake on my car, and I don't need to change map or something else, such a AP...

[yamomoto]

You see only outer side, and I from within, inside. :)
MPS and MS - front and the profile of the sphere. :)

I can say for the validity, new tuning of the maps of Mazda from Piasini are better than the old.
Are more correct.

[magoo]

Hey all,

I was number 5 worldwide to recieve the flash (as far as I know). I have run the flash for nearly a year with no problems ( the flash has been updated along the way ). I really dont know the power gains as I have not sought a dyno out.
As mentioned the support network is small and our local guy "Sassimac" has closed shop. The treatment of those distributing the flash was/has been pretty bad and "Sassimac" was over all the negative hype.

Cheers

[SuperStretch18]

...As mentioned the support network is small and our local guy "Sassimac" has closed shop. The treatment of those distributing the flash was/has been pretty bad and "Sassimac" was over all the negative hype.

Cheers

Yah, I heard Sassi closed up shop. Sorry to hear, as he's a stand-up guy. That said, there was a reason why the flash wasn't so well received and it has to do with marketing. If the flash was really everything that it was hyped to be, then there would be no reason why it wouldn't have done well...

Except if the proper information wasn't put out there. Messing with the internals of the ecu is (and should be) a dicey proposition unless there is enough material to support that the method both 1) adds performance and 2) is safe. Piasini unfortunately never quantified either of these in what the market deems an appropriate fashion. My take on this was that the directive came from Piasini, as it seemed none of the distributors seemed able to discuss any more details. The only real feedback that came out was from users that would typically say "yeah, it rips", but couldn't even talk in detail about what was going on behind the scenes.

There are too many "fuel savers" and "turbonators" in the automotive market for consumers to just believe everything that is spoon fed to them; there needs to be some quantifiable data to back-up the things you claim. It's unfortunate, but should serve as a lesson to anyone. No matter how good a product is, it can still flop if your marketing sux.

[magoo]

There is a lot of truth in that.
I beleive that Piasinis arrogance was the real problem here. They had a great opportunity and blew it.

[8.5MS3]

260whp/330wtq is nice but everone that i know that ran your software has either blown or jump ship to the ap or standback for one reason or another.

[Mz3Hatch]

260whp/330wtq is nice but everone that i know that ran your software has either blown or jump ship to the ap or standback for one reason or another.

Same things that I have heard. Ill stick with a good quality tune via AP and AKUMA! (headbang)

[8.5MS3]

Same things that I have heard. Ill stick with a good quality tune via AP and AKUMA! (headbang)

U get tuned by john too?

I will be heading to a dynojet this weekend hoping to be in the 300whp/340wtq region.

and what the hell happened to piasinis post???

[zaka]

Your AP doesn't work on MPS so it's a sh***

I've already done more than 40000km with the Piasini tune without issue. And I'm sure gain is more than a AP or SB...

hey zaka if you can do this on a stock engine with the piasini lets see it....how much are you putting down?

http://www.mazdas247.com/forum/picture.php?albumid=232&pictureid=1166

local speed3 (18psiwhitems3) - 380whp 355wtq on the AP

[zaka]

Tell me why he cannot???

How much hp do you get with AP on a stock MS3?? only 20whp?? or maybe less...

Everyone with this reflash get more than 40hp /100Nm on a stock MPS, I can show you the dyno datasheet if you want.

[8.5MS3]

i gained 60whp

[zaka]

i gained 60whp

Lol you mean with your Mods (Cobb SRI,...). I told you on a STOCK MS3, only AP!

Ok then... I think if you are happy with your AP, keep it and don't tell bullsh**t about Piasini tune.

Here a dyno on a stock MPS (before/ After reflash):

http://nsa03.casimages.com/img/2008/11/30/081130070854563026.jpg

Bye...

[coyfish]

60 whp on a tune . . . lol


If your breaking 300 whp with nothing but a tune / intake you are asking for trouble.

[8.5MS3]

Why is that? I'm only pushing 18psi?

and zaka I had a buddy with the piasini tune....hes out 6 grand on a new engine now, so its not really bullshit

[Mz3Hatch]

8.5MS3- This is turning into the argument like was had over AMR Tuning. People know its crap but youll always have that one or those few that swear its the best thing since sliced bread. The smart ones of us actually do some research and get things properly done with our cars. Hey, if they go ZOOM ZOOM BOOM its not our faults.

And to answer your question from before: No john hasnt tuned me yet. A few of my friends have been though, one actually just bought his motor from his STi. He swapped it with a Cosworth i believe. Stupid fast now. Im waiting for a few more things before I go, mainly DP,FMIC, and im tossing around manifold. Hopefully by this time next year my car will be where i want it to be.

[Mid_Life_Crisis]

I`m more than a little cautious about the idea of a generic "fits all" reflash. If I`m going to tweak my ecu, I want it done specifically for my particular setup, location, and driving style. This is why I am (still) saving my pennies for an AP.

[SallySpeed3]

If anyone wants to try it, send me a box, I'll remap you for free just so everyone can check out the data and the dyno sheets......dyno

Wow, who's gonna take up this offer?

[8.5MS3]

Strange, we have remaped at quite a few MS3's with Piasani files, and we haven't had a single one go ZOOM ZOOM BOOM, Maybe we're doing something wrong? LOL

Look, the AP is a great unit, no doubt, we tune them here all the time. But it is not the only tuning interface out there, nor is it, in my opinion, the best.

Can you make 400WHP on the Piasini, yes. Can you do it with AP, yes. Its just a different way to do the same thing.

If anyone wants to try it, send me a box, I'll remap you for free just so everyone can check out the data and the dyno sheets......dyno

I think its more of the lack of support here in the US, just like the AP and SB on your side of the pond. also euro spec ms3s have different emissions requirements. having 2 cats and different mapping may be the reason the piasini doesnt work too well over here. just my .02. I know a local guy, who had the piasini tune ended up clogging his cats and decided to go tbe as a result. he blew shortly after, can it be coincidental, sure.

[8.5MS3]

where are you located?

[jmac36]

Heres a dyno sheet from a stock us model MS3 2007 that has had the reflash and nothing else

[8.5MS3]

am i reading this right

stock the car put down 260whp/275wtq?
and after the tune 295whp/340wtq...

something doesnt seem right. what kind of dyno was this done on? considering the car makes 263/280 at the crank im a bit suspicious.....

either way a 35whp/65wtq gain is respectable. how much was boost increased?

[coyfish]

Oh, I have no doubt that you put your finger on the problem. There have been some major screw ups regarding representation over here in the states. When I started with Piasini, I found all kinds of people who just spit when you mentioned the name. Lots of that stems from the fact the "rep" that first tried to sell these maps was not even a rep! That was a bad deal, pissed lots of folks off, and spit out clone remaps in a "one size fits all" dash for the cash

In fact, the euro ms3 has way stricter emissions than even CA. The German TUV is way harder than you might think. But you are correct, there is no way you can just toss a generic tune on a car an expect it to do as well as it could, or worst case, not explode! Thats way we tune everything on the dyno, here, in my shop. We have a great relationship with Piasini, and we tell them what we want, and thats what we get.

At any rate, I was serious about my offer. If ya want it done to show how good it is, let me know.


Meh I came looking to piasani with an open mind even though many people on these boards were very skeptical. After not being able to get responses from anyone for over a year to the shady way you conduct business . . . . it's just not a very good way to attract customers. Maybe you don't want more customers (cant imagine why) . . . Im not judging.

Then Christian Piasani comes on the boards and writes 3 posts in all the Piasani threads. 1 of the 3 doesn't even make any sense at all. All of them contain SEVERE grammar issues. Maybe hes not american. English isn't my first language either. But if I were looking to attract customers I would at least invest a few minutes to write a coherant sentence.

The tune looks great. But I am just baffled as to why Piasani can't make a reasonable thread with pictures and a full explanation of whats going on. Always seems like Piasani is beating around the bush.Most people aren't just going to throw their ECU's into the hands of anyone.

[coyfish]

Oh no that wasn't aimed at you at all. I used "you" meaning piasani in general. Sorry about that. Yes NYPEST was one of the guys I was trying to communicate with about a year ago. Just seems like he would never answer questions directly which got frustrating.

The people on this board that do have piasani seem to be happy with it. I have never seen anything negative related to the tune itself. Its just the lack of communication that frustrated me / many others.

Anyway glad to see piasani has someone willing to clear things up.

[shpankey]

jmac36. I'll take you up on your offer. Where do I sign up? Sending a pm...

[EwMPS]

A lot of us run the Piasini Flash along with a piggy back, Uni Q. Very happy with the tune.

[AllLostThings]

I've been curious about this tune. I'm looking to maybe do this or the Cobb AP sometime in the next few month. It's hard to find info on this and I'm not sure if the AP is the way to go with what I have for mods. I'm trying to look around a bit.

[EwMPS]

Believe it or not one of my Forum members imported the Cobb AP and it doesn't work on our ECU's. For some strange reason our ECU's differ from yours :-( our models are also downgraded from yours.. :-(

[EwMPS]

Copied this from my Forum, just wanted to share this. We are very fortunate that our Tuner went over to Italy to get trained in doing the Flash for our local race cars. There is no support I know of from them except for our tuner trained by them.

Flash.

- Allows full control of the TB, an additional 1000rpm before the TB starts to close.
- Boost limiter removed, can bump the boost right up without the ECU restricting.
- Steering Angle torgue limiter removed, no loss in torque from ECU intervention at various angles.
- The ECU still has its safety features fully intact.
T### tunes the Race MPS's as well as some of the Class A cars I think Audi. He worked in conjunction with Chrsitian from Piasini in Italy (ECU mods for Ferrari, Lambo etc) to unlock the MPS ECU as nobody could get it right... absolutely fntastic flash. The uni Q can't get nearly the full potential out of the ECU so hence the flash and then the Uni Q on tops of it to fine tune the curves.

[08cosmic3]

Buy a used AP for $500, keep it two years and sale it for $500. Buy the flash for ??? and it has zero resale if you want to take it off the car and sale it.

[Bravnik]

Again, the issue is that the ECU in the US is different from other countries. The Piasini flash is expensive for what it is. There is no data to backup the flashes that are done in the US. No car in the US that has the Piasini has major mods and data to backup any claim.

If Piasini wants to sell in the US they need to do some work, get some data, show some dyno's. I'm sure the flash will make an almost stock MS3 drive better. Hell any flash will do that. However, once you are fully bolted the issues arise.

There is simply no way any flash can work for every car. It simply can't happen and anyone with any common sense knows this. A flash is a STATIC change to your ECU. The flash can't adapt. The changes made to the ECU can't adapt. Sure you can make basic changes like full throttle control and raise the boost cut limit as well as the boost itself. That makes sense. However, you can't possibly compensate for mods without custom tuning. Again, a FLASH can't Learn.

[zx2man]

True, the piasini reflash is not for everyone. It is for those who are serious about performance without loss of drivablity. If you want a great tune, with TOTAL CONTROL over base maping, and you want to make the most TQ with a reflash, Piasini is the way to go.

Just carious what Kind of numbers are we talking about from the Piasini flash??????..pardon me I just stumbled in here..dont know the details..but im making 300 ponies and 322lb of torque with my Cobb AP..on a conservative daily driver map and my car's "drivability" is amazing..no complaints at all..very happy Cobb customer..I just would like to know whats the real advantage here??? Thank you for your time.

[zx2man]

298hp 300lb/ft on a load type dyno for a stock ms3 with the reflash

Im assuming thats bhp? not wheel.....pretty decent regardless..stock ms3 263 hp and 280 tq..so 37 hp and 20 tq gain from a reflash? for people wanting to look completly stock then thats a good direction.

[Bravnik]

So let me get this straight; you are saying that a remap cannot learn ie adjust for trims, is that correct? If so, could you explain to me how the factory pcm is able to do this, and a remap can't?

BTW, we have remaped several US market MS3s with both bolt ons and internal mods.

As far as expense, I would say that the dpt/piasiani reflash is very competitive with the AP. We tune with both, but prefer the Piasini for accurate tuning.

Look the AP is a good set up if you want to play with your car yourself. Its a safe setup and makes good numbers. Cobb has great marketing, and good customer service, and this is their market.

On the other hand, it really is a case of tomAto/tOmato. Both work just fine in the hands of a good tuner. Both work on the US cars, the Piasini works on the rest of the world, but I'm sure if Cobb wanted to they could fix that, no problem.

And to your question about data; pick someone, send them over, we will strap them down to the dynapack pull some data, dump and flash.

Jmac - In the US there are no tuners for the Piasini. We can't get a custom tune. I'm sure the product would work if we could but we can't. In the past Nypest sold a one size fits all flash which failed because there is simply no way one size can fit all. That's all I'm saying.

You put up an offer to send an ECU to you to flash. Again, what good is that if you can't do a custom tune for your car? You say you tune on a Dyno...great. But if someone with serious mods sent you their ECU the best you could do was to guess at a tune.

Piasini as a company I'm sure is great. But until they can provide shops in the US with the ability to do custom tunes then the US will never be in their market and a Piasini tune in the US is not a good idea unless you are very close to stock.

In the US we really have CPE, Cobb as major players. That's really it. Besides, the Piasini flash was almost as much as an AP. Dollar for Dollar I would rather have something that I can physically see and sell later on.

[Bravnik]

I understand what you are saying, however we do indeed do custom remaps using the Piasini software/hardware here in the US. We have been doing it for the past year or so with very good results. We never really went after the ms3 crowd because like you say, the cobb set up is very good for the average tuner.

We have several shops that we are working with who wish to become flashing dealers, however most of them are into the NA Mazda 3's, but can do all of the Mazda line, if they want to.

NYpest is a very sore subject with Piasini. I have had several conversations with Christian about that very topic. He is one of the reasons that the tuning is done the way it is now, to avoid the "onesize fits all" issue.

As far as guessing about a tune, no we do not tune by guess, nor do we tune generic files. We can tune your files based on the same dataloging that is used for AP e type tuning. The only real difference is that we do not allow raw bin files to float around the world, and raw file work is done by one computer.

Hope that clears up some of the mis information thats out there

Yes cleared it up real well. Thanks man. I wish you luck. I wouldn't mind seeing Piasini rise from the Nypest ashes.

[Huligan]

If anyone wants to try it, send me a box, I'll remap you for free just so everyone can check out the data and the dyno sheets......dyno

Hey jmac36, I will take you up on that offer... I sent you an email a couple of days ago. Let me know whats up.

[Huligan]

will you be around this weekend? I have an autox event in a few weeks and would like to see how the tune is

[Huligan]

Great. I'll give you a call tomorrow!

[starscream2k1]

Well I might as well chime in:

My MS3 PSI/Piasini Reflash Tune Impressions

Here were the stock numbers: 240whp/253wtq
Here are the reflashed numbers: 276whp/316wtq
As seen as a increase: 36whp/63wtq

There were all done on a Dynapack Dyno, and from what I know it reads lower then a Dynojet, but higher
then a Mustang dyno. Its more of a happy medium. I prefer it because 1) I dont waste tires on the dyno,
2) no slipping 3) no loading the suspension, strapping it down and having the wiggles and 4) its more
accurate in the sense that the reading it taken from the hub rather then transitioning from the tires. In
either case there are gains to be seen.

The dynos were taken with the hood up, and a few pulls were with the fan on however the blasted thing was
too loud and strong (never seen a dyno fan like that), it could blow Dorothy out of Kansas so we had it
off most of the time.

The only engine-type mod on the car is the CPe CBE, and the CPe RMM (if that counts). So a relatively
speaking stock MS3.

The car drives amazingly! The powerband has been shifted up a bit, which I personally prefer as the peak
torque isnt in the 3000rpm range anymore. Shes smoother all round, just driving the car feels well
balanced and smooth on the pedal. When I romp on it (WOT) shes a different beast, I can see the traction
control freaking out in the upper RPMS and when I take off the DSC its amazing what the car feels like
now. Theres power all over in the map sorta speak, and its much less jerky when I am driving compared to
before.

The torque/boost limiters are gone in 1st and 2nd gear, as is the steering input limiters. I can tell you
when taking a turn and throttling it, its fun, much more fun then before with the car bogging or feeling
like your hitting a wall on power.

Boost has been increased to 18psi so about a 3psi increase, however the car ****en rips. Plain and simple
I need better tires now :( LOL. Driving the car around the city and on highways I feel comfortable in
every gear to press the gas a bit to get going, and if I need more power I downshift and WOT it. Power is
on instantly and boost rampup is nice. The throttle control on the car is much more responsive.
All in all, I am happy with the flash and it was totally worth it. I have been monitoring with my
dashhawk to see if theres any changes or worries to be watched (namely watching KR) and there has not
been. If I had known about this earlier, I woulda done the flash sooner/earlier. I would recommend the
flash and PSI Tuning to anyone. However it is important to note that this flash changes the stock ECU,
but the beauty is that the ECU will still learn and increase if you do mods, meaning that it reacts like
the stock ECU but better. BUT note that IS IT NOT for a BIG Turbo setup or for someone doing everything
under the sun. I am more of a set-it-and-forget-it type of person and I dont want to have the hassle of
separate tunes, or retuning constantly and more to point I would rather trust a tuner who has tuned
hundreds of cars and as well as a dozen MS3s then myself as I am no expert in tuning even though I grasp
what needs to be done. The ECU kept learning as the dyno pulls went on, each pull gave us an increase to
the point where we were getting consistent numbers.

I had gone recently to Quys for the informal MS3 meeting, and some of the members there were with me and I took them for a spin. I am sure they can vouch for how the car drives and reacts.

The dynos printer wasnt working so he took a screenshot for us and emailed it. I am still waiting for the
before and after on 1 graph shot, however I can give you the Final Dyno screenshot in the meantime

Note: From what I understand the dyno calculates hub tq a different way and then you switch it to actual
wheel registered tq then the numbers make sense (you'll see 11xx wtq then the proper number) and as well
the bottom number is changed once the system processes the number after the pull. Incase you were
wondering why the number shows up after.

Star, man I'm glad your happy with it! I assume this is the car my buddy Michael was tuning this last week?

Great numbers, looks good!

Yeppers! This was the one he was tuning :P

I keep hearing about these people that have the Piasini tune and have Zoom Zoom Boomed...who are they?! LOL I keep trying to go out and find them seems like when I do, they arent there.

I gotta say, that looks like a very safe torque curve:

155 lb-ft @ 2500 rpms
165 lb-ft @ 2750 rpms
210 lb-ft @ 3000 rpms
245 lb-ft @ 3500 rpms
315 lb-ft @ 4450 rpms

I'ld love to see that kinda stuff reproduced with AP or Standback.

heres mine, its on a mustang, max torque was pushed out to 4k or so.

my dynojet readouts are in my sig....roughly the same shaped curve

Akuma is a good tuner thats for sure, I have seen some of his work. Just curious how much did you spend on your tune alone? not including the AP? I wonder if we had a Piasini guy, and a Akuma guy both tune together....what would happen! :D

(humpleg)

500, but i get cheaper reflashes as i plunge deeper into this moneypit i call a car. o yea im tuned for 18psi, just didnt have enough resistance to hit it on the dynojet. maybe im cresting 300, but who knows. i know brian put down 290 on akumas mustang and it came out to 355 on a dynojet, then he put down 305 on akumas mustang and hit 380 on a dynojet as well.

Akuma's dyno is a real heartbreaker. stock ms3s have trouble getting over 200.

Dynojets are easy to gain hp, no real resistance. The dynopack is a nice middle between the mustang and the dynojet.

Either way back on topic...

You said you knew a Piasini MS3 the went ZoomZoomBoom, do you have said persons username or something. I would definately like to have a chat with him.

myms3

and i believe the order of hp goes:

highest
dynapak
dynojet
dyno dynamics
mustang
lowest

dynapack is good because its the most consistant, mustang gives the most accurate "real world" hp. either way a dyno is just a tool to see hp gains, not bragging rights. unless your a ricer (ricer)

[8.5MS3]

Yeah the roller dynos are sometimes tricky to tune on. I love our dynapacks because I can just set the car at one rpm and load and try different things without having to run thru the whole pull.

BTW, as a general rule, the dynapack will be about 15% less than a speced dynojet, and 8-10% less than a mustang

no arguing, just discussing

it is impossible to compare numbers from one dyno to another. variables com into play not only with the car, but how the dyno has been calibrated. I know Akumas has to be one of the lowest dynos out there, and the disparity only increases with power.

akuma/dynojet

249/286
291/355
305/380
(owners sti)
540/670
(a recently tuned gtr)
612/785

[starscream2k1]

Dyno is a dyno, the only thing is dont compare between different dynos and as well, like in my case dyno on the same dyno, make the change, dyno again. I mean that way you can see a difference as everything was the same other then the flash. Keep as any variables constant, the more reliable the data I suppose.

[8.5MS3]

You are very correct! Can't tell you how many times I have told customers that very thing! It is not the numbers you get, its the delta between before and after that counts!

agreed! also area under the curve. i could care less if you make 1000whp at 1 point, and crap everywhere else, give me 350whp from 3-7k and ill be happy (for now)

EDIT: yes starscream you are correct, its good for before/afters for THAT DAY only. go there when its cooler/hotter and your numbers will be different. its only a tool to measure changes in power in a before/after scenario

[Huligan]

Hey jmac, yesterday I installed the Corksport TBE I bought from you ... and both sound and gains are pretty damn amazing!! thanks again!

However, in the higher RPM ranges (over 4k) and when I give it 70%-100% throttle, the engine is cuts off for a second and I get a small backfire which gives me an annoying jerk forward (as if I stepped on the brakes). Seems like I might be overboosting a little bit maybe? Or fuel cut? Not sure, since I don't have an AP or Dashhawk. I have a boost guage but it's been on the fritz and only works like 1/5 of the time... so I'll have to check how high I'm spiking.

I was wondering, could the Piasani tune help circumvent this boost limit or maybe limit boost to be on the safe side? Obviously I want the Piasani tune for the performance and driveability of more torque throughout the whole RPM range, but I want it to be as conservative and safe as possible.

Will upgraded fuel pump help? Or is it not needed for the mods I have?

[8.5MS3]

Your hitting boost/load cut. The throttle plate is slamming shut to save the engine. I highly recommend you get a dashhawk to monitor your engine. Any tuning solution will alleviate this problem. As for the fuel pump, you need to see what your stock pump is doing before you waste money on an upgrade you may not need.

[Huligan]

meh I feel like if I get a dashhawk I wouldn't know what 99% of the variables mean/should be at/are low/are high etc

ex. I dont know what KR should be at. Or AFR or O2 or AIT or HIJK or LMNOP.

lol its a quick read: major items:

AFR - Air Fuel Ratio - under part throttle it should be 14.7ish or lower, when engine braking it will go up to 30ish on the DH. going WOT(wide open throttle - pedal to the floor) it should drop into the 11's, anything higher than 12 and it could be unsafe

KR - Knock Retard - when the engine experiences an explosion in a cylinder not originating at the spark plug tip it will knock(sounds like a ping if its bad enough) The engine will pull timing (spark later in the stroke) to prevent it from happening. This is bad, you want 0 all the time, especially going WOT. below 1.0 is acceptable. This can happen from a number of things: bad gas, hot cylinder temps (from cruising for a while), heatsoak (sitting in traffic, the air entering the engine gets wicked hot) etc

Boost - obvious

DISI Pressure - Fuel pressure from the CDFP - anything less than 1500 at WOT is bad and you can run the risk of running lean

STFT - Short term fuel trims. the O2 sensor in the exhaust will "sniff" and determine if you are running too rich/lean and make fueling adjustments (example: runnning rich -1.5% means its pulling 1.5% of the fuel it the tables in the ecu are telling it) this will fluxuate all the time as it is instantaneous.

LTFT - Long term fuel trims. If a STFT correction happens repeatedly the ecu says "ok from now on, automatically pull/add X amount when this condition happens" This will reset the STFT to 0, and it will retrim from that.

LTFTs and STFTs are critical because the computer will use these values to determine fuel amounts when going WOT (open loop) verses cruising (closed loop)

Open Loop - Ecu says "fuck you epa fags, I dont give a shit about the environment. same goes for you sensors (most of them) I want maximum power, give it to me now"
Closed Loop - Ecu says "ok epa fag's, ill keep emissions and fuel economy to a maximum" and reads from all the sensors.


Basic intro, hope it helps.
