Well, I finally got it to log, I must have messed around with the protocol settings for 2 hours before I realized I just needed to increase the number of timeouts... But anyway, now that I have logged, what the hell am I looking at? Specifically, I'm trying to track down a hesitation when accelerating from around 3500 rpms. Feels like it's pulling timing and I think the log shows that but I don't know if what I'm seeing is OK or not. The a/f gauge shows full lean right when I drop the hammer and doesn't go rich until I start to let off. I made my runs on saturday, and this morning the car drove fine. Is the ECU "re-learning? Got rid of my CEL so far though... So many questions, thanks for any help Corbin.

You mentioned "relearning", how long has it been since you cleared the ECU memory. How many driving cycles...miles? I'm still learning my software too.

I reset the CEL on Saturday afternoon. Since then I've driven the car 6 times, about 100 miles and so far no CEL. Usually it comes back within 2 days so who knows. The car does seem to accelerate smoother now, and I haven't felt the flat spot I described earlier since resetting the CEL. It may be coincidence, but it's also hotter than hell out right now, so the car isn't acting normal anyway. I did notice when logging spark advance and tps, that everytime the throttle opens, timing falls. When the throttle closes timing increases. Is this normal??

That sounds right cause your knock count is supposed to go down when you step on the throttle, 0 knock count is where you wanna be at right??? This is what I hear, someone say diffrent if I am wrong..
