Default First time logging, can someone take a look?

Car is a 2005 WRX Stage 2, invidia catless DP with Stage 2 91 octane map.

I reset the ECU approximately a week and a half ago and maybe have done 300 miles of driving since.

This pull was done on a tank of 94 octane fuel but the tank before was 91 octane. I normally run 94.

https://docs.google.com/spreadsheets...it?usp=sharing

Im not seeing any feedback knock, so my understanding is that is good, what i was wondering about is the Fine Knock Learning and the DAM being a value of 9.

Im guessing the DAM is the way it is because I haven't driven the car enough since resetting the ECU?

Any input would be appreciated.

Thanks a lot.

Yeah, I think that might have been from the 91 octane I had to run for a tank.


I just reset the ECU again and went for a 20 minute drive and the DAM started at 12 and is now sitting at 15. Im going to drive around some more tomorrow and do another WOT run and see what it looks like.

Here is some good info from Cobb on what parameters to look at and what each one means. Not sure if you've seen it before:

Your car should get the DAM up to 16 when its running properly. Are you seeing any other parameters out of "normal" range?

Ive read through that a couple times, thanks though! This DAM thing seemed a little weird. The only other thing that seems off to my untrained eye is not hitting target boost, and the fine knock learn being a +1.4 at 4000 ish RPM.

As I said though I reset the ecu again and it seems to be better. We will see what happens over the next few days.

Sounds good. Keep us posted. Dont worry much about the fine knock learn - if a positive number it is actually adding back where there was a previous knock event. the ECU doing what it is supposed to.
