http://code.google.com/p/ecureverse/wiki/LaunchControl Maybe the input frequency to the unit could run from pin 7 (tacho output) on the ecu & activate from a clutch switch or button mounted on the steering wheel? For $37.00 would be fun to play around with
Stopping the spark is better than stopping the fuel I guess. Similiar to the Bee limiter in a way. Interesting device.........
Super cheap n nasty launch control, no adjustment and redneck as can be: Hook up a relay to the clutch switch so when you depress the clutch the relay goes open circuit, place the relay up front near the air flow meter and splice it in to one of the wires for the AFM, the white one will do. Now when you put your foot on the clutch the AFM wont work so the ECU will go to limp mode and wont run past 2500RPM or what ever it is, release the clutch and it will be happy again Redneck as and I accept no responsibility for any damages caused by trying it :rofl:
I was thinking maybe the black wire on a series 2 ptu to cut the spark, from what I read it can be adjusted:
Looking at that circuit, it grounds the coil -ive only like any rev-limiter but its specifically for a single coil/dissie setup. So grounding any ptu wiring will result in a short to ground or just a ground to ground. Six of them for a 6 cylinder COP setup. Mungys ghetto solution is very very cool! E
Yes, but will it give us bulk flames out of the exhaust? That's really what we're after when we pay top dollar for the commercial launch controllers, let's be honest here :rofl:
Lol. And here I am using the jaycar frequency switch to control my air com pump in the suby. Might graft this idea onto the rally car. Nothing better then launch control on an old Datsun 240k. Haha
Only when the car is restarted. I tried it yesterday out of curiousity, stalled as soon as it was disconnected.
Ahhhh FICK! well you need a momentary interrupt to the ECU power then so it has "restarted" at each gear change :rofl:
