Even if the ECU reacted to the nitrous as you propose, you still wouldn't be at optimal or safe A/F ratio...as the ECU would not be aiming for a calculated or measured sub 13:1 A/F.

hmm what im doing is using an afc to tune the airfuel based on the nitrous shot and using a moates 2timer to change my maps at the time of nitrous injection, retarding the maps by 2 degrees. Once i figure out how much fuel needs to be added i can get a custom chip made with those adjustments, am i going about this the wrong way?
