So I have a 13B converted from twin turbos to a single turbo.... fully built engine putting out 700rwhp on race gas 30psi. BUT I CAN'T GET THE DAMN A/C TO WORK. I know my fans blow, I know my switches work for the fan and a/c button lights up, AND I KNOW I have zero leak because I paid an arm and a leg to get it charged TWICE. What can I narrow it down to? The dude at the carshop said A/C HEATER CONTROL... does anyone know where I can get one?? I seem to only find JDM ones on EBAY. HELP!! ANY IDEAS?

 

Since you are running a standalone, you will need to program it to accept an A/C request signal from the heater/AC controls and then use an output to trigger the compressor clutch.
