When I have the PWM Ford valve at '0' or a bit of duty cycle on cranking when cold it seems to start ok. But when warm/hot operating temp the motor just screams like you have the throttle stuck open then dies down to the regular RPM for the 5sec (or whatever I set it to).....and to the duty cycle at that CLT temp.

This happens when you go into a store or something.......come back to the car and start it up and then it cranks I guess at the low % and then ramps down to the closed or nearly closed postion.

There is no hot setting for having the valve closed. I don't really need it when the motor is hot.

Well I didn't like it :( Either it was my settings or whatever but the motor didn't really seem to idle at a higher RPM like I thought it would have. I think I had like 36 total at cold and that for some reason barley bumped the RPM at all :?

I had 10 over my total and my 100,90,80 and 75 KPA and 800/1100 bins started at 26-28 and scaled down as the map dropped to idle.

MSQ and log are here........
