Okay,I Have 99 civic coupe just boosted it again and converted obd1 to run my obd1 p72 ecu.I start up the car and couple minutes later I hear a loud whistle like a tea pot when its fully hot and my a/c compressor spits out freon.When I was running NA with a obd2 Si ecu with the same compressor it runs fine doesnt spit out.Im thinking its something electrical related but I dont know what.Im just curious If any one has ever had a problem like this or can give me advice.I dont really want to get rid of all my a/c components cause it is my daily driver and I live in FL.
