PS1000 IAC, wheres the settings?

So, I wired this in but I am not sure where in the software I go to turn it on or change the settings.

I am using the haltech IAC with 4 wires, I wired it in using the dedicated green wires.

You need to enable stepper motor control. The settings are on that page.

Found it, its on the outputs page on the bottom. Do you have a good baseline for the haltech IAC or should I just play around with it?

Start with the default settings. They'll be close. You'll need to play with it from there. Every engine is different. Since the air bleed and throttle stop settings come into play, what works for one engine won't work for another.

Okay I have it working pretty well but ran into one problem last night after driving around for a bit. The idle started to target 2000rpm instead of 1000 rpm. When I powered off the car and restarted it would target 1000rpm for about 3 seconds and then jump to 2000rpm. It seemed like no matter what I adjusted would help. Any ideas?

When I revvved the car and let it fall it would try to idle at 2000rpm as if that was its setting. Oil and Coolant temps were around 180.

Cold Temperature 95
Cold Target RPM 1400
Cold Start Duty 75
Cold minimum Duty 15
Cold Post Start Offset 50

Warm Temperature 165
Warm Target RPM 1000
Warm Start Duty 15
Warm Minimum Duty 0.5
Warm Post Start Offset 5.0


----

After some more investigation

The Stepper value was 100, I just saw the On Throttle Position box that is at 50% for both boost and vacuum. (mine is a n/a car with a recent rebuild) and this seems like it could be the problem. I don't see where I can change the value of the 'zero throttle value' like the page mentions though.

I bet ^ setting is just in the TPS settings isn't it?

The 0% throttle value is a combination of the min position, start position, and your PID settings. What position is the valve actually running at when it's idling warm?

It was at 100 out of 200 max. However I adjusted the zero TPS setting in the TPS section to 2% and it seems to be a lot better. I am thinking that taking the vacuum number down will help the flywheel come down quicker though, I have a LWFW and right now I think the 50% at vacuum holds it up when I shift. Its actually kinda nice but I think it can be better.
