Launch control not working !

[martroy]

Hi,

I'm trying to use launch control but doesnt seems to work as expected. Heres the situation;

MS 2/Extra and the latest firmware.

I want to use it with ground input. I was looking to make a jumper between JS11 and SPR4 and ground pin 6 to make it work.

Without the jumper, by selecting JS4,5 or 11 in Tunerstudio, launch control active himself like if something is grounding.

What should I look at? Thanks everyone.

Hi,

I've build low input circuit and have 4,91v on JS5 clutch out and 0v with clutch in. When engine is running, clutch in, clutch out or wire disconnected from Pin 6 makes launch active when RPM and TPS condition are met.

I dont know what should I look at.

Thanks for helping me.
