LS1 PCM Controls

[LTb1ow]

Just thinking out loud here, is there any way to manipulate a sensor input to use a temp sensor to control a ground/switched hot out?

Was thinking about the pinouts, and there are a few things I am not using anymore, so wiring up and programming the PCM to see trans temp and to command on/off a fan would be fancy.

Aeroforce Interceptor pod gauge will do all of that just by being plugged into the DLC
Basically how I have mine setup actual Coolant temp instead of the crappy dash gauge and Trans temp displayed underneath.
Then if and when I want to manually turn on the high speed fan setting through the Interceptor.

While that would be simple and easy, I do not want to spend more money and I already have to many guages.

What year PCM and harness are you using (if not a custom harness)?

[LTb1ow]

Custom harness, no clue on what year the PCM is, but not a 98

Did you make it or have it made? Does it have the wiring for the egr solenoid?

[LTb1ow]

I made it, its a re-pinned LT1 harness.

So yea, I could wire in an EGR

Ok cool. Let me look through some of my tunes and I'll get back to you. The EGR wires are monitored by the pcm and can be used for "other things".
