Anyone had the software update for low pwr under 2000rpm

[phebert]

Just wondering if anyone here has had the software update done as described in bulletin 01-0153/06? It is titled "Lack of power or hesitation on acceleration under 2000 rpm". See

http://www.mstore2000.com/PDF_Files/01-053-06-1737b.pdf

I was thinking of asking for it - my 7 qualifies and the hesitation bothers me - but was wondering if it makes a big difference or if you notice any downside.

[otnielarencibia]

They said engine power output is unchanged.....That might be true but I'm afraid of 0-60 times....

[erhayes]

Why afrade of 0-60 times?

[mikey1981]

i dont want this update. the boost is nice once you get used to how/when it comes on and how to somehwat control it

[CXRabbit]

I had the upgrade done and notice the difference. The acceleration is still the same as far as the time it takes to get up to top speed, it's just a more steady acceleration. I don't get that "dead spot" at the beginning, especially when trying to accelerate from a rolling slow speed (like when you roll through a stopsign LOL).

Mikey - you may not have a choice. Dealer won't always tell you when they do PCM updates. It may also be at some point that it's required to get another later update.

BTW, I wonder if anyone has noticed a change in fuel efficiency since this update?

[dmitrik4]

one of the things i noticed when rolling very slowly through stop signs, etc is that often, the transmission doesn't shift down to 1st (or even 2nd); a lot of times it stays in 3rd until you get back on the gas. So i think part of the hesitation is the time it takes for the transmission to shift once you start rolling onto the gas again. i don't notice any hesitation from a full stop.

CXRabbit, what difference did you notice exactly? During the first 2 wks that I had the car, the hesitation is really noticeable. But now, I know it is still there but I'm used to it now. I love it when the boost puts me back on my seat. So would you recommend this update?

[CXRabbit]

Shaz,

At first I didn't like the update so much because you don't get that drastic "push back in the seat" feeling. However, it's a big improvement (at least to me) over the lag in the beginning... and I'm still way out ahead of everyone from a dead stop. The car lost none of it's get-up-and-go, it just all feels smoother.

Would I recommend it? I think it's important to keep the system on a new car like this up-to-date... so I do think you should get it. Plus, it's going to be difficult NOT to get it as sometimes the dealer will just do the updates during a regular service visit. On a new car THEY want to keep it up-to-date too.

I am curious if anyone else with the update has seen a change in the fuel mileage (MPG)... because mine has been a bit crappy the last two tanks. Now, that could completely be ME and the fact I do A LOT of around-town, short-trip driving... but I wonder if the update has anything to do with it or not (which is why I put the question out there). During this current tank of gas I'm purposely taking a less direct route to work now because it's all highway with only 1 traffic light, instead of all back roads with tons of stop signs -- but the distance is about the same -- I wanna see how I'll do.

CXRabbit, I had the upgrade applied about 3 weeks ago and I haven't noticed any MPG change. I have run about 3 tanks through since then and I am still getting between 19 and 22 like I was before I took it in...

My dealer is a pain about PCM updates, they tell me that "they applied any updates" and then I get on the highway and it's obvious they didn't.

Is there any way to check that they applied the update? do they have to put a sticker or something on your car? I just need a better way of checking.

I printed out the service buletin and I'm going to go back to the dealer and makes sure they do it, but it's just a pain to have to double check every time.

[phebert]

Thanks to all on these replies. The bulletin specifies they apply a sticker so you should be able to verify the update. Sounds like I will ask for the update -

Newbie here, I had mine done couple weeks ago noticed big difference in performance.

Newbie here too, whats up guys, I just got mine last night and i also notice the lag at take off under 2000 rpm so i guess they havent done the update to mine, does it cost anything to do this? oh and where on the car do they aply the sticker so maybe i can check to see? thanks:)

Congrats. What color did you get? I got the Electric Blue. Click the link below and you'll know where to find the sticker.

Looks we are getting the update with the oil change on Tuesday.

I got Black on Black, and I dont see the stcker so I guess the dealer hasent done it to mine yet, I guess when i talke it for the 1st "free" oil change Ill ask. Thanks for the info by the way :)

[Alpha Wolf]

I had mine done.

I noticed quite a big difference from before.(ughdance)


There is more power off the line and not such a hit of power at 2500 like before but overall accelleration is good..(first)

I have noticed it now appears to let the engine rev up near 3,000 before auto shifting even at light throttle. (first) So it does not pop into 5th so quickly now..

Overall drivability is better. If you really like the hit you may not want this update as it really reduces the HIT...

I picked mine up at the end of DEC. I would have thought they would perform any required updates before delivery, but I don't see a sticker on mine. I don't notice a lot of lag but I'm not sure.

[milhouse19]

I need to read more.

[CX7nCali]

my MPG actually got worse

i'm lucky to get 300 miles out of a tank, that's if I take it easy

Interesting... do you know how much worse?

I was listening to the car shift today and it's definitely different since the update. It seems to be reving up to higher RPMs before shifting than before the update, which might explain some efficiency loss... ?

Hmmmm

[hectik1]

Just got the update....feels pretty good.(drinks)

[CX7nCali]

about 1 or 2 mpg

i'm averaging 17 mpg

[Platonium]

Haven't driven enough to guage economy since the flash, but it definitely addresses the low RPM soft spot. I also feel like it holds 1st and 2nd a little more agressively. It might also advance the timing right off idle to give more power. Glad I use 93 octane. We'll start measuring econ on next fill-up. I recommend this flash if you feel like you're lacking power off-idle.

[Shaz]

I had the update done today and yes, you will feel the difference. The hesitation is gone. the one thing I did notice is that when i was cruising down the Interstate and was gunning at 80mph, I'm still on the 5th gear and tach is playing along 2500-3500 rpm. Only when I went past beyond 3500 rpm that it upshift to 6th gear. Not sure if that's a good thing but the shifting and acceleration is much smoother....no turbo lag and no hesitation.

[simonxda]

Hmm.. Just wondering this new update will actually give have a higher consumption. I also having the problem of achieving high gear, most of the time 4th on city and 5th on highway before going to 6th.

[hectik1]

A little city driving/a lot of highway the CX7 got 340 miles on the tank. Figured it out to be 22 MPG. This is after the update.

Also speedo is a little off....got it to the 120 mark on some open road.

[mb011b]

I guess I am spoiled with driving manual tranny all my life but I was hoping for a bigger improvement from the PCM flash. Drives me crazy waiting for the auto trans to put itself back into gear or downshift when I hit accelerator. It is better now, I guess, but seems like maybe a slight improvement to a big problem. I'm going to have to play around with the manumatic shifting again to see if it is less active with putting in clutch/neutral now.

I did get a sticker on my doorframe, above the tire-pressure sticker.

[Otto]

So what is the concensus on potential MPG hit with this update? Is there one?

[pipsthedog]

I just had my software updated today - a noticable difference in the smoothness of the shifting between 1 and 2. I will watch the mileage. I also had them replace the seals on the bottom of the doors under the service bulletin. No more slush up the inside of the doors and the noise level has gone down dramatically. It is almost like having a totally different vehicle.

When did the service bulletin for the door seals come out? I haven't heard anything about this one.

[Zoombee]

OK, I found the Service Bulletin for the door seals on the other Mazda forum.

Someone needs to start a Service Bulletin Thread so all of these can be added as people find out about them. I am not sure if I want the update on my PCM but I can't stand all the dirt getting in under the car doors. I will get that fixed with my next oil change.

Talk to them first as they may not have the parts on hand. I am still waiting for mine on back order. It's been several weeks now, which is irritating when I allow myself to think about it.
