Fuel cut and recovery rpm bin changing?

    Fuel cut and recovery rpm bin changing?

    I have a pocket rommulator on my Z31. I was wondering if anyone eber altered the fuel recovery after fuel cut on their Z31 and could possibly shed some light on the situation. The Z31 fuel cut is laggy and when trying to slide if it spools up too much and hits rev limiter, the recovery is far too slow and all sorts of mayhem occurs. So if anyone has any info regarding the bin location for the fuel recovery and fuel cut rpms id greatly appreciate it!

    your hx35 is whats fucking you up. spool time. i had the stock t3, ecu and fuel on my 86. i never had fuel cut issues bc i had all my boost by 2700…then id shift BEFORE rev limiter. we are talking about drifting right?

    Do as I. Set the fuel cut to 7500rpm (via Nistune, f*ck Romulators anymore)…get spark cut limiter and set to ~6500, or whatever.

    Thats what i was going to do with my bee r last time but it was a little too aggressive. What spark cut do you use?
