Gammae jumps to 55% from 92

During hard acceleration I get jumps in the Gammae value and it surges pretty bad. Its pretty constant at 92%, but jumps to 55% for an instant, causeing the pulse width to drop to almost half.

Looking at the datalog, when it happens, it shows that decel occurs after the jump in gammae. Decel ...

Re: Odd readings from NB02.

What are you using for your warmup enrichments and cranking pulsewidths? I have a motor that is very similar to yours, and a base setting for these values would help me alot.

At idle, the NB02 reads about .62 volts. As the engine gains RPM, the voltage reading drops, indicating a leanout, even ...
