Hi. I'm a newbie in Tunercat and programming GM ECM's.
I have a 1995 Corvette LT1 with 4LL60E, that I've put in a 53 Suburban, and I would appreciate some help. I bought a standalone wiring from PCI conversion.
I had to remove the V.A.T.S before I could start the engine.
The fan came on after I started the engine, and stayed on. And I have some problems to start also. It needs som cranking before it starts.
I tried to change the setting for the fans, but now I get DTM on the fan control. ( MALF 77: Fan 1 Fault, and MALF 78: Fan 2 Fault)
I've tried to reprogram the ECM to the first file I read out from the ECM, but I still get this Fan fault.

Any ideas anyone?
