Stalling problem after cold start
My GoStreet 400 starts fine when cold, but wants to stall. If I rev the engine just after starting, the engine speed rises then drops below the set idle speed, but recovers just before it stalls. I have increased the after start and warm up fuel settings with little effect.
Try adjusting one of these:
Fast Decay 20F= A larger decay will shorten the amount of time that the injectors are adding fuel during a transient. A smaller decay will extend the time. 0 will use the default values that are in the default calibration.
Looks like you would go smaller.
Also found this:
Tipout -20F = “Tipout” is the term used to describe when the throttle is closing. The MAP drops rapidly, which means vacuum increases rapidly, and the fuel suddenly vaporizes off of the wall, and the injected fuel quantity is less. The wall film of fuel will decrease greatly, and thus if the injection rate is kept the same, the engine will be very rich. The software compensates this using a default calibration for the wall film, but the adjustments provided here can allow more precise adjustment for the varying engine configurations.
Tipout 0F = same
Tipout 40F = same
Tipout 70F = same
Tipout 120F = same
Tipout 150F = same
Tipout 185F = same
Tipout 215F = same
