here is a small project that I installed VEMS on to. This car had a WAR chip installed with a air mass meter conversion but I guess it never ran correctly.
It came to me with no ECU so I installed a VEMS 3.6.
This car is running 42lb injectors with stock ignition and a custom turbo kit that the owner installed himself. I only added a M54 idle control valve, m50 TPS and IAT sensor from the webshop that is an open element.

The only problem I ran into with this car was the A/C engaging. It was a much larger load on the engine than normal, and i'm not sure why. I changed the PID values and ref table but it wasn't enough.
Since this compressor on signal is a 12v and I couldn't use that as a input to the VEMS I installed a relay.
pin 85: 12v from compressor on
pin 86: body ground
Pin 30: ground from sensors EC36 pin 26
Pin 87: to EC18 pin 2 analog channel 5 (pull up 5v)
Now every time the A/C is switched on used the same config as before but raised the idle by 100rpm and raised the IAC ref table up about 10 points across the board. This made a big difference in the way the car drives, before when driving at low rpm you could feel the compressor cycling on and off, now its nice and smooth.

Well executed solution .
I´ll be in Vegas tomorrow!!. Only in the airport going to San Fran though. Otherwise I would have looked you up!
Are you coming back through Vegas? Delay your flight for a day. You have my email.
We will take you out for a night!
I wish I could have known that, car didn´t arrive on time so weekend was mostly as waste.
I´ll be flying out of San Fran rathern Vegas. I´ll try next time around !
