so i wired up most everything from my SEM, and now there are two wires for launch control, one is for launch ground, and the other is input, where does the computer get the signal from for launch control?

 

44 views and still no answer...........

 

signal to activate launch control?

 

yea! what?

this a fuel cut or ign cut that you're setting up?

 

wow.. come on people..


Generally features like this get the input from an unused pin on an ecu.
which pin you can use

Obd1 pins you can generally use... if i miss one feel free to comment in the correct
ok for instance in neptune RTP

You have to look in your manual to see how to activate the inputs/outputs
