When I say "should" I realize there's a bunch of stuff that determines when PE turns on that depends on more than just 1 variable but I don't know how complex the calculation actually is. Suffice it to say, I did a scan recently and noticed knock that shouldn't be happening. The O2 readings didn't rail like they should have under some fairly heavy throttle. Have a look in the attached log to see what I mean. I did a bunch of excel analysis and I believe this is fuel related but I can't figure out why it's happening. Anyone have any insight?
