And while I'm at it, when the trans shifts, after it completes the shift it feels like someone tapped the brakes....like it's pulling timing or something. My torque management and shift times are identical to what they were before. Is there some other setting in the engine parameters that controls torque during the shifts?

It's really ******* frustrating that I've never seen the full potential on this motor. God forbid I could get 27 degrees of timing with no knock

maybe look at the trans abuse stuff. I would Compare the tunes and look for things that would do something like that. But I kinda dont think it will let you since you changed OS....

It's got the 2002 knock sensor settings. Basically the sensitivity is zero'd out from the factory.

It's pretty obvious to me that this isn't false knock. But I cant hear any knock. That's what's so confusing.

Well for starters, your running pretty lean.... Have you done anything to the VE or MAF tables? Did you disable PE, cause at WOT your O2 sensors are switching and your commanding 14.63... That is why your getting alot of KR.

I haven't disabled anything. It's a bone stock 2002 LQ4 tune.

Regarding the trans abuse settings, they are identical between the tunes.

Post up the tune, cause from the look of it your not entering PE... Don't go WOT until you get it fixed or prepare to buy a new motor soon....
