What is CarSpeedForRevLimitWithTBOff used for?

[player1up]

I've gotten my tune pretty well dialed in but I'm having an odd issue with idle as it relates to the A/C being on or off. ( BB flashsable SMEC )


Car runs fine with the A/C on if I turn it on at idle or while at speed, but If I cross 10MPH and then slow down below 10MPH, the idle jumps to 1800 and hunts for a few seconds.
Wideband shows swing between lean / rich until it calms down.

... and CarSpeedForRevLimitWithTBOff is set to 10MPH...

That's a rev limiter setting. Nothing to do with AC or idle.

ah, ok thanks Rob, I'll look elsewhere

There's a rolling AIS setting. That's probably what you're looking for.

ya know, I was looking at those the other day, but they didn't make sense to me so I left them alone. I guess I was trying to correlate the 10mph with something
For example what do the values correlate to? ( what does "4.000 out" mean )

RollingAisDecay -- 4.000 out ( time ?)

RollingAisHighLimit 32.000 out ( number of tabs on the limbo bar ? )

RollingAisLowLimit 4.000 out

RollingAisMaxSpeed is 16.000 out ( MPH, speed sensor ticks per second ? )

RollingAisMinRPM 7.782 out On my car this equates to around 70-90 RPM ( description says it's RPM added to base idle when rolling... makes sense i guess because my rolling RPM is 1020ish and stopped idle is 950ish based on the gauge not MPSCAN. MPSCAN is pretty much dead on with the IdleSpeedParkNeutral FromTemp table ( like 10-20rpm off but it's such a small margin and not something I've even bothered to think about )

During some testing at lunch I realized it's not a sure 10 mph slowdown thing. 99.9% of the time it's at 10mph during slowdown, but I did have it idle normally once all the way to a stop, then it started freaking out once i was stopped.

...my head hurts, good thing it's Friday...

One reason I've been putting this off is due to the ECU learning and the number of times I'm gonna have to flash it to find the issue....

Is there some sure fire way to tell when the ECU has completed it's learning cycle?
