ECU reflash at Mazda

[Shane5425]

yep..

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.

That is simply not true. Why would you post false information?

It is the fuel pump control algorithms that have been modified.
This reflash has absolutely nothing to do with changing the target AFR under any load condition.

So basically this relfash just changes the PID settings? I somewhat understand how proportional integral derivative tuning works since injection molding presses use that logic in order to stay in the process window to mold a good part. Im assuming PID works essentially the same no matter which application it is used in? **** I need sleep lmao

I summarized someone else who usually has good information. I wouldn't knowingly pass on bad info.
I was a lot more excited about this when I thought it was changing the mix.
Oh well, I'm scheduled for next Saturday, and I'm still going through with it. I have unpredictable power levels, and I figure this can't hurt. Sometimes the car is fast, sometimes it is merely quick, and once in a while it takes off like a rocket (which scared the hell out of me the first time it happened).

I'm scheduled for next tuesday, and I'll push for them to inspect the build date of the pump. Dealer said no problem. Will report back also ...

I took it in this morning and they said they would have to "recreate" the problem as well.

My issue is that while I know I have experienced this issue in the past, it is illusive and appears at random times. At least when I went in today, about 3 people heard my story about what the car does under 75% load when under 45 degrees; sudden power loss.

The TSB also mentions something about random power loss when engine is warm. Again, lately because of the "good" weather here, this is also hard to emulate. I feel that my car runs best on a partly cloudy day around 55 to 70 degrees F*, exaclty like the conditions today so no issues when I brought it in. I think I am going to wait until there is some freak weather and leave it for them to "diagnose"

I just hate that THEY have to prove it. My VIN should fall into the "Just needs reflash, not extensive work" for this TSB, It just sucks they wont preform the maitenance without them driving it.

Wow, amazing how some dealers can be such assholes. Does your vin fall under the TSB or not?

 

[TurboWagon]

There are 3 categories your car can fall into about this TSB.

1. Your vehicle needs both a reflash as well as the HPFP replacement. (Those produced before 4/7/07)
2. Your vehicle needs just the reflash. (Vehicles built between 4/8/07 and 11/22/07)
3. Your vehicle does not need work.

My car falls under number 2.

I really dont understand why this isn't a recall. If the engines are experiencing varying and intermittent power surges and falls, why not just preform the maitenance to prevent further problems down the road?

If they drive my car though, I want to ride along. There is no way I am letting them take my car for a spin without me inside.

Mine falls under number 1. Although my dealer is cool with me and all, they decided to order the pump with no questions asked. Mine has a built date of 08/06.

Open the driver's door and look down next to where it tells you how much air to put in your tires.

Since my reflash my car always feels strong. I also had a cobb intake installed that day too so it could be attributed to the intake. Maybe both. All I know now is my car pulls way better than stock hot or cold out. When stock power not as consistant.

I was surprised when I read this thread. It explains the first syndrome I experienced the weekend before my last service on April 1st: "Rough idle, stall, and/or hesitation under cold conditions".
I ask the tech to see why the engine stops twice after 5 seconds on idling. The car was rough to drive for the first 2-3 minutes, then returned to normal.

They couldn't do anything because their computer was not working and were waiting for a replacement from Mazda... I was told to call back in two weeks and they would start by updating the ECU.
I presume they knew a new version was available but didn't know the existence of the Service Bulletin (dated April 2nd).

I'll try to go for the update this week.

Pump is in, dropping the car off tomorrow in the morning. Asked how long it will take, service said they have never done one before. I am alittle worried....hehe... Oh well...

 

[wisniaPl]

they told me around 45 min

 

[knowledge007]

Thats nice...maybe I'll just come in a little late tomorrow to work then.

 

[wisniaPl]

so should i get it on my 08??
