idle issues with A/C
 
2 Attachment(s)
I'm just getting off the ground with my MS setup. Driveability is great, but idle could be a lot better. Idle without the AC is not terrible, but with AC is a mess. Oscillates and eventually dies out unless I play with the throttle.

I read through this: http://www.msextra.com/doc/ms3/tmp/2Idle_Control.html

Using that as a guide, I tried playing with the proportional and integral controls but didn't make any headway.

Any tips? I've attached a short log of idle with AC.

Try adding more duty through the A/C idle up duty menu. Also post your msq.

I have not yet played with the idle outputs, so I have never done what you're asking about. But one thing jumps out at me:
In the chart you posted things start happening as of approx. 130*C. You should rarely get to that temperature at all. I believe our stock thermostats are set at 190F, that's 88*C.
Maybe the chart has *F and *C confused?

That is an interesting comment. I'll have to go and look at settings, but I just pulled that picture when the computer was not hooked up to the car. I don't know if that has any effect on that readout?
