Raising Idle On DSP5 Tune

[SmokeShow]

Can this be done? I'm was thinking of a "back door" way of having a high idle on my truck for faster warm ups on the cold mornings without having the normal high idle function wired into my 02 lb7. Am looking for one tune on the DSP5 to have an elevated idle RPM. I don't see how to do it because the idle parameters are only in the base tuning calibration tables. I suppose maybe the base tune could have the elevated idle RPM and the rest of the dsp tunes would then have what kind of idle? Would they also be elevated?

If this is possible, a brief "how to" would be much appreciated.


Just been thinking.

maybe add a little pulse width in the idle area, I dont think the fuel pressure table would yield very good results, but the PW table just might, its worth a try at least

I know it's done through the throttle based injection quantity tables. Basically you up the 0% throttle portion and it will add fuel to raise the RPM's. Wiring in the factory fast idle isn't hard though, and works pretty good.

yeah, I know it's not hard. Was just thinking.

Larry I dont think that wont work because the ECM will still do whatever it takes to maintain the desired base idle speed.

All adding pulse width will do is make it surge and run like crap.

Changing the idle speed in the base tune will change idle in all tunes. What would have been cool is to see that idle speed table also in a dsp tune or all of them.

How about ramp up B0702, then in the winter time your a/c switch is your high idle switch.....
