Default Jumpy Idle

Okay, i get a jumpy idle from 900-1000. Is this MS related? All i've done is calibrate my TPS and did the basic timing setting.

I still need to burp my radiator, but i didnt have the problem before MS. Any solutions?

Shoot us a datalog of this occuring to [email protected], along with a description (I'm out of town and it may be Matt that looks at it) and we'll see what we can find...

In our base map the Idle control code is configured to control idle within about a 130rpm range... so it want take steps to 'correct' the idle if it's within 130rpm of 950 when fully warm. You can try tightening that up a bit, but too tight and you can cause it to overcorrect. The idle code is a bit touchy to tune but should work pretty well for you-- My car feels pretty much like stock with the settings in the base map.
