I get the 0 timing so you know when you hit knock, but its not pleasant when you are driving in traffic or something and it occurs.... copy your primary map and take 4 degrees out or something like that. You can still see you had knock with your logs.

It happens at any RPM when apply throttle. Any load I apply at any RPM causes the AFR to go lean and then back to normal. This is an S13 KA24DE which has the SCV Butterflies removed. Maybe the ECU is programmed to pull Fuel to account for the SCV at partial throttle?

p00t wrote:So here are my suggestions at this point:
[*]Try a different base ROM (an sr20de one if possible).
[*]Try a 300zx n62 MAF
--->there are likely Alpha-N type functions that think the high maf voltage at low-mid RPM is a bad MAF. The bigger MAF has a lower voltage at those points and doesn't trip this logic.
---> Just trying to help because I know from my experience with an n62 MAF I have never encountered this in KA or SR tunes. I have also not encountered this with sr20 map and stock g70 maf

I'm only bugging you about this because the issues fits if it is at least still using the fuel knock map, which you have zeroed (14.7:1 AFR). This would make it lean until knock went away or you went out of the knock cells with TP or RPM.
