ls1 DBW swap w/0411 ecm elecctric fan and a/C question
im swapping a ls1w/4l80e into my 98 gmc truck and I want to run electric fans and use the ecm ability to control the A/C system. I have a p01 ecm out of a 02 chevy avalanche. the ecm has all the options for electric fans and looks like all the stuff for the a/c control. can I use the settings from a corvette and turn all that stuff on? and would I use the corvette pinouts to wire in the sensor, and use the corvette pressure sensor?green truck ecm original 5.3 avelanche (do not write).hpt
For the Electric fans, yes just use this diagram to connect them to the PCM.
The AC, your going to want to use Trinary AC Pressure sensor from a Fbody i believe. But it will control the fans from the sensor information.
Dont use a truck stock tune to go off of if you want to wire in the AC Pressure sensor. The corvette or camaro tune would work.
I'd use the 01-02 F-body calibration if you're planning on running a DBC throttle body. It'll be easy to do a segment swap on that OS.
You can use the trinary pressure switch for the AC as RDF1 said.
