So, i just ran my A/C lines further away from the turbo for better cooling.
Now my A/C is not runnung.
I found a setting for A/C in the AEM program.
When I checked out it said (switch always off)
I changed it to (switch always on) the A/C ran just fine but it wouldn't switched off.
There was other settings.
The question is:
The AEM unit runs the A/C?
and if it does what setting are you guys using?
Any help would be appreciated

i dont think ems runs ac. im sure ur suppose 2 keep the stock ecu to do that.if u hav ethe harnes its suppose 2 connect the ems stock ecu to run ac and the wireharness together.

I have it plug in that way.
It's just weird that I can activate the compressor with my lap top.
there is a setting for high pressure and low pressure activation.
Also there is an RPM compensation for it.
Thing that would off come in handy cause I had my cat at 1400rpm at itle to compensate for the A/C .

AEM EMS is setup that way cause on most cars you do not use the stock ecu with it.

A/C Min 500rpm
A/C off above 90%
A/C on delay .52 S
Idle A/C 3.91%
A/C Switch #3 Grd=On
A/C Clutch LS6

Use these settings and all should be fine.

Thank you
I'll try that will get back to you
What about the parameter settings?

 
Rep Power: 329

tried the settings with no avail
I got it to run on A/C switch 3 ground = off
but it stays on at all times no regular manual control
I got booth fans on delay
I change the rad fan to LS6 and it did the same on always

Do the fans come on at all? Or is just not operating under the default switch?

fans work under the default setting.

I did all the changes as you suggested.
Compresor still won't engage.
I experimented under different setting and the compressor works, the whole system works fine but it won't shut off manually.

I called AEM they sugested that I change the A/C parameters from
A/C to switch #3

I tried your settings in combination with the parameter settings and I get the same issues on all the time or off all the time.

This is very stange!
i got to get to the bottom of this.

I do appreciate all your help.

AEM tech support can't figure it out.
I took it to an electrician and he jumped a wire from the ECU to the main A/C switch.
It all was going good, I drove the car home with a cold *** interior.
Right?
So it started to rain and ,I turned the headlights on, and the compresor stoped working WTF
So I have to go back and tried to figure that out.
