El hardo, are you disableing the fidle port before choosing idle control? It sounds like yours is acting like mine acted on the stim before I figured out you had to disable the port before choosing pwm warmup? I may not have any idea what I am talking about though. It seemed to me that if I enabled the fidle port, that it listened to whatever was in that table instead of the pwm warmup table.

I got the same problem going.

0% duty cycle and Stim idle LED is on full, 100% duty cycle is off.

95% I can see is dim and down to about 65% I can see the LED is not full on. Any lower than that and it appears to be full on. This part I think is normal. But the dutycyle numbers seem to be reversed. This will work as far as I can see if I just reverse the values, but it seems something is wrong.

It seems that at 100% there should be full current to the idle valve and that should have max idle RPM with full opening of the idle valve. At 0% one would guess you should have no opening of the idle valve and have base idle settings. Is this logical?
