I have a 2010 camaro ss E38 ecm.
Whats your take on disabling the compressor at higher engine RPM's?
Does the tables in Systems/AC params G0103/G0104 work?
If so, which pin on J1/J2 would connect to the compressor thru a relay?
I am using a VA a/c system with a trinary switch to control the fans and would add another to control the compressor rpm on/off?
If that works!
Thanks, Chuck
is this on a custom swap?
Yes...It's in a 55 Chevy
E38 will not be able to control AC compressor by itself, it needs can data message to activate it, you need BCM and AC controls, there is a company that sells a module to produce this signal.Quote:

why not use ECM to control Fans?
Yes I am using the ecm for fans. I miss-spoke. I meant using to trinary to control compressor.
It appears the settings in the ecm for ac rpm is non-functional.
I guess I'll have to remember to turn off the ac if I do burnouts.
It may not be critical to be concerned about compressor rpm since my Sanden SD7B10 is 6500 constant and 9300 downshift.
I guess GM quit using that control like the LS1 when they started using control modules to consolidate wiring.
Thanks for helping out.
not sure i understand. will a/c control (g0101-6) work on a 07 ls7 c6z06 or not?
