I've searched a lot. What does the ECU Periphery00 (F9A) Bits Do? I've even posted in ECUFlash questions. I think questions in there get buried.

I've seen numerous ROMs have 1's in different areas and was curious if there is a thread or does someone know what each bit does.

I would try each one, but a little nervous about it. Just my luck it could be the lean out by 3.0 AFR and increase timing by 10* at peak timing.

 

did you look in here

Actually, that was the first thread I found when looking for answers. I went to http://evoecu.logic.net/wiki/Periphery_Configuration, but it just reiterates what's on the thread.

I think I'll post a comment on there to get the attention of the disassemblers.

 

bump I'm curious also..

 

I'm curious as to the answer to this as well....

 

I don't think anybody knows. I'll have to find someone who's a lot smarter than me to figure it out. Bummer...

 

This was posted today in another thread regarding the F9A.
