Fuel cut w/ low injector d/c??

[Earley]

Can you hit fuel cut while your injectors are not at full duty cycle??

Today, on the way home from work, we did a couple hard pulls, and I hit fuel cut, but the injectors were only at 77% and the 02 was at .71 at WOT.

Thanks...

Stock ECU will cut fuel at a certain airflow/rev amount.

Yeah, fuel-cut is caused by air flow and has absolutely nothing to do with fuel flow. That's one of the tricky things about understanding it.
