Never figured it out, ended up trading the car in just because I needed something more practical for a daily driver.

The knock would show more times than others for no apparent reason, it might...

I just would like to know if I'm headed on the right path here with correcting my LTFTs. Do these numbers seem like they could be are correct?

12.07 x 1.035 = 12.49AFR

12.07AFR on E10 is equivalent to about 12.49AFR on E0 (regular fuel).

Alright I'll work on that first, thanks.

Edit: After reading a thread on E10 Fuel, I agree and think this is having some impact on my LTFTs.

I'm thinking I will change the PE value from .80 to .89. Do you think that would be good once I verify that the commanded AF is near the actual AF?

Thanks for explaining that to me. Do you have any idea what could be causing the injector duty cycle to be at 85-90% in these log files?

I am in the north east where we all have 10% ethanol at every pump, it sucks.

How much will having 10% ethanol in the gas change the tuning process? What things should I look out for because of...

Completely stock tune and that log was not altered in anyway. Stock tunes are pretty bad commanded AF is 11.7!



Thats good to know, looks like I'm going to have to do a lot more reading and...

I'm just starting to log data and I noticed I'm getting some KR at WOT. Also injector duty cycle shows 86% that seems high for a car with only intake manifold, throttle body, and cat-back exhaust...

Thanks, that fixed it!

Hi, I'm really new to this and trying to just get logging down first. I ran into this problem does anyone know what could be causing it? I attached the log file that I'm having trouble with.
