Launch Control Not Working In Gear With Clutch Depressed
I just got my MSPNP installed and tuned with the autotune feature on tunerstudio and decided to set up launch control. Well it works fine in neutral with or without the clutch pedal depressed, but as soon as I put it into first with the clutch pedal still depressed it revs freely. I was thinking the clutch switch is bad, but I would assume that would make the car either 1. not start or 2. start without depressing the clutch pedal. Neither of those is happening.
Any ideas?

which mine originally was. makes sense now. i'm getting off work in about an hour so i'll try to do it then. where exactly is it on the trans, i could spend the time finding it, but i'd like to be able to unplug it before i leave here, and go directly to summer duck drag strip
nevermind i found it on mitchell

it runs pretty good. i'm still tracking down a massive boost leak, so i'm hardly building any boost. So i guess you could say i'm not a good judge right now.
and by the way. the reason LC wasnt working in gear is because the spring in the clutch switch was broken. so i replaced it with a click-pen spring. works just fine now.

Well, I'm having an odd but similar problem... My launch control is on at all times, when activated on the ECU.
I was tuning it with autotune before, so this never happened, but today while cruising I noticed the car won't rev past 2500RPM, and ignition retards to 5º. That's the launch control being active. If I disable it, the car revs just fine.
Should the launch control not work, or do I have to check if my clutch switch is broken? Should the circuit be closed or open, for launch control to be enabled?

do you have a vTPS? since you have a 91, I'm assuming no.
if you watch your throttle input gauge, youll notice it's constantly increasing to 100% i bet.
you need to make sure your throttle % threshold is set really really really high, in fact I wouldn't use launch control without a vTPS.
