No, they do look very bad, especially for E85. -1 from time to time is expected on any fuel -2 or -3 is not, that indicates the ecu had to continue to pull timing over a duration to stop the "knock event"

Fuel trims are a minor concern when your throwing -2 and -3 feedback correction events.

@swe-gt86 - do you have a fuel tester, do you know for sure what blend ratio you are on? Also, you would do well to post an actual log file as well as the screen shot, there is only so much detail you can see from the screen shot.

Yes, many degrees before that.. 40 degrees is surely beyond mbt and could be to the point of hurting the motor.

Never once did the IAM Value drop infact it kept rising. So my theory and I'm still waiting on @FA20Club.com to respond to my logs that it wasn't real knock. It was picking up bumps in the road ect and reporting it but the knock sensor was not seeing enough to pull timing?
I have seen an occasional -1 from bumps etc, unless you have some clearance issues (metal on metal) i would be looking for a tune revision to see if it may clear up those events larger than -1.

Ive driven this car like this since i got this in july. Think my engine need some new spark plugs and coilpacks atleast... Yes the fuel was pure e85, they dont mix e85 on summers.. Thanks for your help guys.

I think your best bet is go to to a local tuner.

Looking on ecuteks website these folks should be able to help you out

JRM Racing AB
Mpart AB
ProMotech AB
Trollspeed AB

I have dealt with TrollSpeed Personally with my Saab(been to trollhattan) and I have heard of JRM so I think maybe if youa re close to any of these people start there. Remote tuning is also very nice with the right people which I know people on this forum will be able to help as well.

Looks like it could be tip-in knock, perhaps? All of your recorded knock correction events (especially towards the end of this log) seem to correlate with what looks like you flooring it. A log showing the throttle input might help confirm or disprove that theory.

I sent logs in. I've been waiting. I'm also waiting on hardware
