ECU reflash at Mazda

[dread]

So the pumps have changed in the production since august 06 when my car was built?

 

[SHAGwagn]

mine falls under this date, guess ill take it in too. What do i do? Just go see a service guy with the bulletin printed in hand? I cant say I'm experiencing those problems but **** it...if theres a reflash then i want it!

 

[Shane5425]

Just tell them that a ecu update is available and they need to check the computer by pluging into you car and see if it is applicable to your vehicle

All I know is, is that I have been experiencing the problem listed. Rough idle, stall, and hesitation. So I am going in tomorrow with bulletin in hand. I have complained about this many times. I have even had them clean my fuel injectors to see if that was the problem. 100 dollars later same problem. I have let this issue go but now that there is an update, they are going to here from me tomorrow.

Well just got back from the dealer and they are going to replace the pump, or w/e needs to be replaced. Hopefully this will solve the problem with my rough ildes and hesitations during startup.

Glad to hear that in a roundabout way you're getting something for the $100 you paid for an injector cleaning. How'd they get you to do that? Unless you using extra cheapo gas from day 1 or something, there's no way you would need an injector cleaning using normal gasoline. That's what detergents are for.

 

[knowledge007]

I don't know really. To be honest I went ahead and went with there recommendation with the cleaning in order to document the issue of a rough idle and hesitations during cold startups. So that if and when something like this came up, they couldn't tell me that I have never mentioned anything of this sorts.

They also can't blame my exhaust due to the fact I had them install it in the first place...hehe. I work in security and safety which cover claims and all kinds of s***. I know how to cover my ass....lmao

BTW, this car has tasted nothing but Chevron premium.

So, the question remains... If you have not experienced any of the symptoms listed in the bulletin and your car falls within the build date prior to Nov, 2007 (my build date is 09/07)...should you get the reflash? I have no complaints in power, but if I could get more, then hook me up yo!!! (lol2)

Just wondering...

I've read in some other thread that someone got an emissions reflash that the car ran like crap afterwards.

DAMN. my dealer just gave me a reflash and said see if that works then come back if it doesn't. I came with the memo in hand as well. I didn't have the rough idles though. I pulled both the 2187/88.... i should have spent 100 to get my injectors cleaned!

 

[dread]

your dealer is lazy, its there job to see if it worked not yours. How does the car feel after the reflash

 

[SHAGwagn]

yes please let us know how it goes wth the reflash...i dont have any problems either but wouldnt mind some more power.

So it sounds like this reflash leans the mix, but still at levels the factory considers safe, which is what we are all trying to do, so the reflash sounds like a no brainer.
As far as what pump to go with, that sounds pretty obvious too.
If you have a pretty much stock vehicle that qualifies for the corrected pump, get it! Mazda thinks your current pump may not be able to always supply proper fuel to your engine and they are willing to fix it.
If you are heavily modded (or plan to be) then a properly functioning factory pump is not going to cut it for you. In that case you need the upgraded pump from our resident expert and all around helpful LilGuy. ...or from those other people if you like them better.

I have been pulling the 2188 (burning rich during idle) a couple times. FYI, this TSB does not cover the 2188 code. Usually this code signifies a boost leak of some sort. What CP-E recommended to me was that I should tighten all my hosed and clamps and clean my MAF sensor. Whiched seemed logical considering my car was in the body shop for over a month and I am sure moving the car around that place the CAI filter picked up some s*** and landed on the MAF. The MAF was alittle dirty. After I tighten all hoses and cleaned the MAF the 2188 hasn't come back...(knocks on wood)...

i just had mine done. i have had a slight puttering at idle, and you don't have to be throwing a code to get the flash. if the flash does not help, then they go in and inspect the fuel pump. my car does idle much better. i did not notice any power increase driving it.

What is your build date? From my reading of the TSB, it appears as though your dealer should always replace the fuel pump if the car was built before 4/7/2007 and the fuel pump's manufacture date was before 3/26/2007.

For cars with the older fuel pump, I'm worried that an ECU flash without the fuel pump upgrade is going to cause problems...

+1

I am also concerned that just the PCM update will not be enough. My car was built in 08/2007 I am not sure when the fuel pump was built.

It should not cause a problem. The purpose of the reflash is to lean the mix a bit and therefore take some load off the pump by reducing how much fuel it has to supply under load.
It can only help a weak pump, although it may not be enough, in which case you will still need to have the pump replaced.

Yes Mid, but what he meant was on he bulletin itself it states that if there is no record of replacement work on the pump, pump needs to be replaced.

My VanDam dealer said that we will start with the PCM then do the pump if it re occurs.

Since the reflash (yesterday). No problems. No hesitation. Much more acceleration. As long as it holds I'm good.

I just got my 07 ms3 serviced. Had the mm recal done. On my invoice it also says PCM recalibrate. Is this the reflash you guys are talking about?
