Thanks for the advise guys. I am going to try the aux 7 settings tomorrow. Should I set aux 1 back to not inverted? And although I think this may help with cooling I am not sure what to do with the high idle with AC on.

I went for a drive today and after warmed up and driving, idle went up to 2000rpms and that was with ac off.
Also I noticed my fans were on before even warmed up. Aren't they only supposed to come on at 93c.
I adjusted the throttle bypass screw all the way closed and it only brought the rpms down 100rpms. Please help I dont want to have to go back to the e420c to control idle.

I got my idle back down to 1000 with the ac off by inverting aux 1. Why does the initial post recommend not inverting aux 1 but jeff-man and my idle work better with it inverted?
Also my rpms still rise at idle with AC on or when I move my steering wheel back forth.

Just as an update and for future reference Andy had me change a couple things that helped with everything. This is what he had me do.
[QUOTE]Your digital in 4 is configured as Active High, it should be Active Low - sorry I didn't see that screenshot earlier.
Aux output 8 is actually the aircon clutch, aux outputs 6 and 7 are the two fans, so Aux 8 should be set to Air Conditioner. You don't want it to come on under any other condition, otherwise you could hold the aircon compressor on and dump your refrigerant and that would be bad.
So please change:
Dig in 4 to active low
Aux out 8 to air conditioner
I would suggest leave aux output 6 as it as in the picture, and change aux output 7 to OR 9/10, so that both fans come on with the aircon.

Could you post your revised map? I think my digital outputs are screwed up and my AC compressor took a dump. Could be something to do with this. Thanks.

aux 6 water temp 90-93
aux 7 water temp 93-96 (never used ac however if you do use it make aux 7 to be "or 10/11" and make aux 10 to be 93-96)
aux 9 water temp 89-91
aux 10 water temp 92-94
aux 11 ac
Since i was using the 420 to control idle my digital inputs were as follows to boost rpm a a sec before the fans turn on (only way i've ever found to keep the motor running when the fans initially would hit).
digital inputs 6,7, as none (act low)
digital input 9 electrical load 2 act hi
digital input 10 electric load 3 act hi
digital input 11 electric load 3 act hi
Since u have a vvt model i dont know what aux your vvt control is at.
aux 7 water temp 93-96 (never used ac however if you do use it make aux 7 to be "or 10/11" and make aux 10 to be 93-96)

From a different post with a different problem dealing the stock idle.
Question: is this a black sticker ECU or a red sticker ECU?
Is this a new installation?
The black sticker ECUs have a pull-up resistor (to 12V) on aux output 1, so that people can use it as a 4th ignition channel without external components, which were confusing a lot of people and making a lot of business for people selling ignition coils and ignitors.
The plugin board is supposed to work so that when the output from the Adaptronic is off, it's a high value resistor so the factory ECU thinks that it's cold, and then when the output is on, it connects another resistor in parallel so the factory ECU sees a lower resistance value.
If we have a black sticker ECU and we set it up in the way above, then this won't work. The factory ECU sees an incorrect voltage on the coolant temp input and aborts its charging process.
The easiest way around this is to swap aux outputs 1 and 2 in the e420c settings, and then swap the brown and red wires in the 6pin plug where it goes into the ECU.
I'm sorry about this limitation, it comes from trying to make the ECU do more things to more people; hence why we went to the vehicle specific units for the Select line.
