19LBS injectors idle rich

Post by jz2518 »

My engine only idle good if i tell megasquirt that i have 40lbs injectors . but i really have 19lbs injectors. If i put that i have 19lbs injectors , megasquirts runs rich at idle but it has good throttle response. But when i tell it it has 40lbs the idle is better but it hesitates on throttle. I have a external fuel pressure regulator set at 40lbs pressure.

Sounds to me like your dead time is set way too high. Are these Hi-Z or Low-Z?
