PWM idle control - closed loop

Hi All

Got my PWM idle control valve working now using warmup only mode, however I CANNOT seem to get closed loop to do anything at all!

I've switched on the idleDC gauge, and it just sits at the 'closed' value permenantly.

Can't figure it out... Whatever temperatures or thresholds I set I just can't get it to move at all. Warmup is fine though.

Out of interest, I started the car using warmup mode, then made the change over to closed loop, hit 'burn to ECU' and haven't restarted it yet - does the swap between warmup only and closed loop require a total restart?

Thanks

Right - sorted it.

It was the TPS threshhold value in the idle control setup - was set to a value of '2' that is way below my closed TPS ADC value of 12, set this value to 70 (i.e. way above 12) and it now works fantastically - car idles perfectly at all engine temps I can curretly expose it to (in our UK heatwave!)

Thanks

Will.
