    ecu Warmup enrichment

    Which table are you guys using for warmup enrichment? I've tried Ivt open loop tables, but doesnt seem quite right. Afterstart is a little lean. Which table are you guys using with best luck?

    So after a log, it appears the fuel injectors are shutting off for a moment, not the warm up enrichment causing the start and die. In the log you can see the car idle then the injector Pw go down to 0.0 then come back up. Not sure why the injectors are shutting off momentarily and come back on. Have any of you guys seen this, and what could cause it?

    Since you are running ve table only, it probably needs adjusting for idle in the area where it is shutting off.
    Under fuel--transient, you might want to make the fuel delta min .015 and see if that helps. You also have the base gain table zeroed out.
    Have you looked at your boost ve table? Don't do any wot with that table, please.

    Its on 20% m1 meth injection, that is why the boost table looks crazy. I will try the fuel delta min, and try changes to the base gain. But why would injector Pw literally shut off?
