FiTech Dual Quad
I have the Accel Pump and Fast Accel settings at 60 for both at 65F and 170F.
The DFCO Return Fuel is at 130.
With the 4 speed, if I ease into it, it will pull great thru 1st, second until about 3200 rpm (then wants to start to stumble), 3rd is fantastic, and 4th I'm either going too fast or contempt.
The AFR will go high and it will stumble if I hit the throttle hard from the get go, or sometimes when grabbing a lower gear to get back into it. The AFR also goes higher at idle.
I increased the DFCO to add more fuel when getting back into the throttle, but it's not completely solved.
I also decreased the Decel open IAC by 10 to reduce the time it takes to return to idle.
I have not touched the AFR Targets.
My understanding is Fast Accel does not mean full throttle, but beyond the initial Accel Pump setting, or roughly more than 50% throttle.
Should I continue to increase these 3 settings, Accel/Fast/DFCO, or are there other settings to consider?
Should the AFR be higher at idle?
For cold starts, should I continue to increase the Crank Fuel, or should I manually open the throttle a little and keep the throttle open/rpms high during warm up?
I've read a tr can foul plugs on cold starts w/o a higher rpm on warm up.
