Can't get enough fuel at high loads with injectors in sync mode.

I understand that the duty cycle needs to be above 90% for consistent async fueling at high load.

Has anyone devised a method to calculate settings from one to the other without it being a stab in the dark (or basically starting over)?

 

I dont think settings need to be changed. I recall it flips asynch why less fuel is needed (idle) and when more fuel is needed(AE/PE). I dont believe your OL. choke - cool coolant - AE - PE will be affected. and CL is just looking stoich. Do you have room to increase FP(and change BPC) to achieve adequate fueling?

 

Very slow MPH for that time

 

is this with a stock fuel pump? stock injectors?
have you changed the Pulse width. increase the LV8 Accel enrichment multiplier vs Delta.. change your ECM injector flow rate a few points higher.. lower % TPS to enable PE. Increase crank fuel PW Multiplier
