i replaced the busted ass tape player for a busted ass cd player.

So, I connected 12 & 13, unplugged the two white connectors next to the trans, and turned launch control on in megatune. Nothing. The little box at the bottom of the megatune window still says launch off too. WTF?

I wish my Link ECU had launch control. I’m jealous.

needs more tps....i guess.

booo @ that hypothesis...

The safety switch is grounded when in neutral, not in gear. You can have both plugged in - and no TPS - and have the launch control still work.

hrmm.. I wonder what's up with mine then.. I suppose I'll go try a few configurations.

what settings do you have for launch control?

im thinking maybe the rpm or tps settings may be off so its not activating right

i could never get mine to work without TPS, which is why I went and got it done. but again is this not with the MSPNP. It's quite possible that the TP input needs some sort of voltage, just so it know it has a signal, and you can easily then use the tps calibrate button to make your throttle 100% all the time....i dunno, fishing. talk to mr cramer, he's smarter than i.
