z31 no fuel cut on deceleration

[gardner86zx]

Fuel cut on deceleration worked before I had my z31 tuned. I checked nistune and the tps switch is working when the throttle Is closed. Any idea what could have caused it in the tune?

Check TTPmin and the the Fuel cut/recover tables

I loaded my old tune just to make sure I wasn't nuts and fuel cut worked on it. I will check tomorrow thanks

also check injector latency value,if its too high,it will disable decel. fuel cut.
