Cranking Idty Duty Resolution

Post by boostedr36mk3 »

Can this table be expanded to 10 temperature points like the other charts? Any reason why this would not benefit? I would like a finer resolution to control how high my car idles up over the 180deg chart during startup.

Yes seconded, I have found 4 points is workable but have often though to myself a few more would be better

If doing this, ought not the crank to run taper have a similar graph? In fact. it'd almost be easier if all of cranking pulsewidth, idle duty, crank to run taper, ase, wue all appearing on the same graph. I'm guessing most people would want a longer crank to run taper when cold than when warm, as a hot restart probably needs very little coaxing of the engine to return to where it had been running.

kind regards
