my build date is 10/2012 but my original rom id ZA1JA00C.


Curious how you have an earlier build date but a latter rom id??

But you are also on 00C rom id correct?


I might try porting my tune over to 01C rom file.

I was on 00d until this past June. That's when the updated flashed got sent to everyone with the transient table fix. since then I have been on 01d


Im on a auto that's why its 00d not 00c

Ecutek.

The IAM should default to 0.7 on every startup (or to whatever your tuner has set). Some cars (seems the push start in particular) "remember" the map you were on or the IAM. Not sure the exact reasons. The fine learning however, stays after resets. You'll see it as the learned knock value.

How can fine learning stay if IAM resets? Fine learning works in conjunction with the IAM, otherwise there would be no point. I know for sure my fine learning resets when the IAM does.

I can confirm the same behavior. fine learning resets to 0 on start up.

FWIW, my car, that does not see the IAM reset overnight, is a BRZ limited (push button start).

you know what maybe ill try the trick that makes ecutek remember which map you are on. I think it goes turn the car to on but don't crank it. turn it back off and the quickly back on and it should point to the map that you last left it. during the summer when I was on e85 I could get it to start on map 3 all the time by doing that. however I use mainly map 1 for my pump gas map.

for sure give it a shot, but im not using ecutek and never have so it may solve the issue for you, but not for me.

Well does brzedit have the option of multiple maps like ecutek? if it does.. does it remember which map you were on?

I was going to say maybe some leet haxor can figure it out and send us some code. Oh wait don't want this to get shut down. lols im sorry

lol,
No brzedit does not support map switching. They do chance a few things in the rom in unused space, like adding the customer name, and some other info, i originally thought it may be something to do with the changes ecutek and brzedit make to the rom file... but that does not seem to be the case.

I did notice the other day the IAM Value stuck until I cranked the car. I started to log before I cranked the car and the value was there and then reset to .7 when the car got spark. ill try to find it when im not drinking and playing gta

I didn't do it, I was busy... and slacking a bit. But I think you're on the right track with what moto posted. I think the battery is similar to a cmos battery. Turning the car on before starting it gives it enough juice to keep it in memory while the engine cranks and keeps the settings. If there isn't a software solution, perhaps there is a hardware solution?

Is this really a problem that needs fixing?
