oh when i depin, should i acutally take it out or can i just cut it?

 

If all else fails you can just buy a stutter box that does ignition cut launch control and install it, not ideal I know, but it would get you launch control...

 

those guys are Speedfactory are pretty smart. Have you asked them for help with your issue yet?

 

Make sure your TPS is properly calibrated, you can check raw voltages with Freelog if you don't have a voltmeter.
Otherwise, use a new ROM. Using the custom TPS plugin in a P30 base can jack up the file, so if you have abnormal TPS voltages then your best option is a gold file or an OEM TPS.

 

still to this day i have tried everything there is besides switching out the bar harness and dash harness, this will still not work. i just recently got a new throttle body for this car and recalibrated tps and still nothing. talk about bringing a thread back from the dead but damn i wish this would work
