I have been trying to find some information on controling the launch control by your a/c button.

This is the only thread I could find.

https://www.homemadeturbo.com/forum/...?topic=32691.0

says something about hooking up the a/c switch to B5 on the ecu?
I dont have a/c hooked up at all, but i still have the harness in the car.

Could someone explain to me exactly what i would need to do to control the launch with the a/c or any other button?

I am running uberdata currently. with a 4000 rpm launch control setting. I dont like it always on, because then i cant do burnouts too easily.

Thanks.

 

The A/C button is connected to the ECU already I believe. I'm pretty sure there's already a script to handle this. Look on pgmfi.org

Although, I'm prolly thinking about Crome...

 

search the ubderdata forum. its there.
