Seriously considering….

[TURBO3WAGON]

I’m seriously considering getting rid of my Speed. I tried the K&N and she’s still stumbling like a drunk sailor with two left feet. I paid 20k for a Turbo protégé the bucks like a bull at the rodeo, this is ridiculous! I love everything else about the car, but I can’t look past the fact that this car runs like a pig. The sad reality is that 3.5k- to 4.5k stumble is right in the middle of the power band, making spirited driving very unpleasant. Maybe I’ll have better luck with an RX-8 or STI. I’m very disappointed and totally confused on what to do at this point. Anyone else feeling this way about there Mazdaspeed??



:(

[1sty]

Has anyone diagnosed the cuase of the stumble yet?

[Stealth5]

wanna trade for a p5?? no stumbles at all

[TURBO3WAGON]

I'll pass on the P5,

Thanks anyway.

:rolleyes:

air/fuel mixture. a stand alone will fix that no problem. the cai fixes it apparently.

[1sty]

But what triggers the higher a/f?
I am thinking maybe FP can make something like they did for the regular protege. The o2 modifier tricks the car into thinking its getting a 14 A/F while th FPR dumps in fuel to get 12.1.
Maybe go backwards. get something to restirct fuel while the car thinks its getting the rich mixture it wants?

Turbowagon, calm yourself my boosted brethern. There will be a fix, from Mazda, shortly. (within the next month or 2.) I believe they have gottne the message, when people started calling, and Email Calloway, and Mazda corporate, and decided not to piss off a major marketing tool, (us enthusiasts who own thier products)

[1sty]

True calling a complaining won't hurt as market response.
However that ECu reprogram has been a promise for over 6 months now.

[TURBO3WAGON]

I’m doing my best to be calm about this; however, the only time my car runs the way I think it should is for about 10 minutes in the morning when I first take off. After those 10 dream like minutes the stumbling starts. I love to rev it to the red line, but what I like even better then that is being able to have clean power delivery with out have to dog it to the bone. It’s either one extreme or another with my car, there’s no mid-point. I can drive like grandma and shift before I hit 3.5k or pound the shit out of it, right through the stumble. I don’t know, I really don’t, this sucks.

I hate feeling disappointed with my Speed.

[1sty]

I totaly understand, all the proteges seem to do that, the 10 minutes before the engine drowns itslef in its oun heat it is great!
Even my turbo MP3 does this a bit.

[TURBO3WAGON]

All cars do it to some degree, but the combination of heat & stumble are a speed halting combination. Hey, at least the car handles like a champ, but I don’t think that’s enough to keep me content..

Joe has the cure for your stumbling. Mine is gone!! $25.00
(kwiktsi) Many have already purchased it.

[SaaBaaDoo]

I was cruising down the highway on my way to work this morning, dropped it into 4th to pass a car, my rpm's would NOT go past 3500, so I lifted the foot and hit the gas a few more times....nothing changed. I myself am sick of it too, but i'm not about to take a big it on a car I just got a couple of weeks ago!

I feel ya turbo3wagon!!! Sad part is I took mine in when it was doing this before and they said it was normal!!! (attn)

[spoolboy]

I know exactly what you mean. the last week or so it has been getting hotter here, and after driving for about 15 minutes or so my car starts running like total shit. No power and very inconsistent jerky acceleration. I have the k&n on it right now, but I think thats coming off, and going back to stock airbox to see if that helps at all. I really don't want to sell it, but if this doesn't get fixed she might be getting sold....... lets go Mazda. Do something

Dude, calm down. All us MSP owners love to drive fast, you just have to have some discipline. Keep your car in a higher gear then you think you should untill you want to pass or race. It seriously works. I keep my car in 5th gear even when driving only 35-40 MPH and only shift it down to 3rd when I need to make a pass, or want to hear the turbo whistle, and it's never failed me. and here in Texas we've been having 90+ days for the last 2 months.

The only time I ever felt the stumble was when I let my fiancé drive it for about an hour. She kept it a gear too low the entire time (most of it 75MPH in 4th) and when I got back in the driver's seat 20 minutes later I thought something had broken.

Before you go spending all the money on an RX8 or STI try putting a little investment into your Speed. The K&N filter won't do anything to lower intake temps or adjust the fuel ratio, which seems to be the main causes for this stumble. Getting a front mount intercooler or fuel management system will. Doing a search on either here will provide you with the information you need, and both would be thousands cheaper than getting a new car.

[TURBO3WAGON]

Kwiktsi's fix is for the excessive fuel the car dumps up top while in open loop. I have it, and it helped up top only. The stumble remains with Joe’s kit, the hood cowling off and K&N in place.

:(

[funnylittlman]

I took my car out after I f*ked up my gauge lens, and it was bucking like a girl on prom night. It seems like it just keeps getting worse the more it gets warmer out. I feel you Turbo, I'm getting really mad as well

[TURBO3WAGON]

FMIC, yes I am considering it but it’s a $900.00 investment and the results are still undetermined. I know it will run stronger if I get the charge temp to drop, but who can grantee me that the stumble will go away? I’m not sure if I will to take that $900.00 plunge on a hunch.

[funnylittlman]

Nothing will stop it! It is invincible :D

[boostisgood]

Thne Issue is the K&N, The cooling fan/wind itself, is throwing HOT ASS AIR into it, thus, creating the stumbling. Trust me, I have dyno proof my prother.

You can see where the cooling fans kick on, and the loss of torque. A heat shield shoud fix alot of the issue, or relocating the K&N further by the headlight.

[1sty]

do you think its the hot air thats the stumble or the temp sensor cuasing a increased fuel dump when its not needed.

[TURBO3WAGON]

I have the stumble with & with out the K&N. I also have a heat shield on the K&N I stuffed behind the headlight.

[Aaron]

i fell ya i am too sick of this shit. but i am in the progress of ordering the fpr kit from Joe seems like this is a small price to pay for all positve feed back from the people who have it installed on their MSP's

My K&N is still in place (until a CAI or short intake), and with the kit (FP), my MBC (not that this has anything to do with the stumble fix).....my stumble is gone.

[TURBO3WAGON]

I’m going to try mounting my temp sensor on my roof to see if it gets rid of the stumble.

Greg, you are a lucky man.

[yashooa]

Man I hate hear this I was driving like a maniac on the way home yesterday and it ran fine. I never ever have had my car hesitate. I feel for you guys my runs almost perfect. I am almost afraid to put on my K&N.

I drive about 100 miles a day in traffic and it has been in the mid 80's to upper 90's and I have had no problems in the heat. It does lose a bit of pull but all in all it runs well. I do get a very small pusle above 4500RPM at WOT in 3rd and 4th gear but it is hardly noticable. I would have been the terror of my dealer if my car ran as bad as yall's cars do. I hope it get's straightened out.

[1sty]

Wire it in front of the radiator.:D

[TURBO3WAGON]

It's barely noticeable at WOT, the problem occurs at partial throttle.

If only I could tool around at WOT all the time!

:cool:

[505zoom]

I feel the same way as you turbo3wagon. I have CAI, and FP kit. Somedays the problem feels 10 times worse than others, and it isn't very consistent about when it does it. Almost ready for an STI or EVO, f*** the new RX8, who knows what kind of problems that new rotar engine has. I would think though, that increasing boost pressure would increase the amount of air going in and thus make the A/F not so rich. Maybe this is why AGR#7 has no more problems.:confused:

[TURBO3WAGON]

Rotary Power!

I’m a Mazda fan man…

Perhaps boost would help, but I don’t want to have to pull all my mods off the day I need to service my car at the Stealership.

What a drag, been there, done that

[TURBO3WAGON]

Thanks for that support guys, but for today I’m out of here!

[unwrittenLaw]

I wish I could just jump into an STI or an EVO..but these are a lot more money than a MSP. I don't think I could go from a 20K car to a 35K+ car...

I think every new car has issues, but the MSP is still a great car and hopefully the problems will get resolved. I think things are getting better just need to have some patience...

But do whatever floats your boat...

Tell you what I will let you know when I get my in August. In fact I will post everything up when Spool is done with my car. Just try to be a little patient.......and I will let you know how all of it goes!!!

Wow I have never experienced that. I would be quite livid really.
Well hopefully this mythical flash fixes yours but mine aint getting flashed period. Well unless it actually makes the car run better i.e. more POWA!
:D

[slug420]

yea, whoever gets flashed first, dyno before and after!

ill even take up a collection on the board here to cover your costs
