throttle tip in Hey guys. The last time I logged I had my car at 94% ifr and 94% pe with 02s reading about 945. I know this is prob. rich, but that's not the problem. I punched from about a 25 mph roll in second and shifted at about 5000 rpm, and as soon as i hit third i had an instant 4 deg. of kr. This kr gradually dim. until i let off at about 5000 rpm in third. The kr happened in cell 15 with one 02 dipping down to 840. Is this what caused it? It was only in cell 15 for one frame after i shifted and then it went to cell 22. My question is why would i reduce the timing in this area if it didn't do it in second gear with the practically the same gms/cyl. It seem like it was a fueling problem to me. Is this an area where my ve table needs to be adjusted? What do you think? thanks for your help!! Oh yeah, my mods are LT's, ORY, lid, and free mods on a 98 TA M6. I'm using hptuners to tune.

When I see KR it's always about the same conditions (4K rpm, and right after shifting I think). Maybe (just a guess) it's because it momentarily goes out of PE mode when you let up on the throttle to shift. So for an instant it's using the fuel trims, if they're negative it's suddenly lean(er).
