I would I go about hooking up launch control to an on/off switch? I was thinking of combination of a red led to know when its on and the switch by the shifter.

 

So come on what would be the best place? I was thinking of just using the clutch pedal sensor but have that disabled makes me scared. Don't want to have some jerk moving car and smashing it someone else because he left in gear. Is there something i can do with the plug on the side of the ECU. One of the plugs says it is for launch control just not sure if it would turn it off... I got some really nice switches with this red cover so it can't be turned on by mistake etc.. that really looking for a home in my car. Please help!!!

Got some RED LEDS and radio shack today and plan on make my shift lights as well

 

Well, the switch used for the launch control would be a momentary pushbutton and you can use it on the wiring from the UTEC.. But as long as that clutch switch is connected, it will still "Enable" itself when you shift (clutch in) so you have to choose which is more important.

The good news is there will likely be more control over this launch control and flat shift feature in the new firmware (because it was a feature request upgrade that has been requested/complained about by almost everyone)

For the time being, I don't use it, I find I was more consistent without using it.

 

People should know about my setup already

I did exactly that. I have the clutch sensor wire cut and ran it to a momentary switch. When I hold the switch it lets the UTEC know the clutch is in. When I release it, I have no more two-step. That is the ONLY way I could get the car to launch well and still shift when I want.

 

Yeah thats going to be my solution when I finally get around to it.. Until the new firmware is released..

 

Honestly I think it works great. John Shepherd has the same switch in his car (He uses the AEM EMS but same idea on the switch). Obviously it works

 

I guess you hold the button to start the car..

 

Nope, I believe that switch it the other clutch switch.

 

oh good.. I never noticed the two switches under there..

 

Yeah There is a lower switch and an upper switch. It has been awhile since I did anything with that stuff but I am pretty sure the only reason the UTEC sucks at launchcontrol and shifting is because they used the top switch (Which means the clutch needs to be ALL the way out for it to un-engage). If they would have used the bottom switch it would have been much better. I think it would still not perform the way I want it to though, I need a launch RPM and a flat shift RPM. Once they get that it could work, set the launch RPM to 5.8k and the shift RPM at 8k or so, then when it hits the next gear it would still be gaining in power not losing it or holding it.

 

Oh and sorry, to answer the question of HOW you do it... you cut the top clutch sensor wire and then wire the circuit to any switch of your desire (So you could have a momentary, rocker switch or an "air fighter" type switch that has a cover). Its pretty straightforward, one wire goes to one pole and the other wire to the other pole. I would recommend using coil wire so it doesnt look stupid also. And this switch has nothing to do with the car start function, that is controlled by the lower switch.

 

Anyone have a good source for good looking switches, including ones with a cover to prevent accidents (looking for something for my alky kit and maybe this launch control as well)?

Thanks.

 

You should do a write-up in the how-to section

 

www.mouser.com I get most of my stuff from there..

 

Otherwise go to Radio Shack They have very small momentary switches or toggle switches, metal switches, all sorts of crap. It costs alot more than Mouser does but then again.... do you care if it is 0.08 cents a coupler compared to 0.50? For the UTEC it is a MUST if you drag race or ever want launch control. Using the launch control without doing this makes the car stupidly slow and bogs between EVERY shift. Now I can get good launches (Im not that good but the tires light the hell up so it obviously is sending power down) and between shifts it will spin the tires when I hit second so this method works pretty well. The only downside to it is you can only have one rev limiter aside from the launch control. In my case, I go through the traps well past the redline.. Hopefully at high boost I will be around the 8-8.4k when I pass the traps. It kinda sucks to rev the car that high when it is a stock head/motor and EVERY shift will bounce up there if I dont hit the next gear fast enough. But for most people this isnt a problem.. I would think most people using the UTEC will trap under thier red line so they wouldnt have to worry about over-revs during shifts. If i blow the motor going through the trap at least I get my good time but if I blow it shifting to second I would be pissed
