I need help wiring my launch control to a wheel trigger.

Can someone tell me how this is done, I have searched the forum but no details.

Thx.

Wheel trigger?? Not for this style launch control. I think you're confusing traction control with launch control.

With the 034 setup it's just a human controlled momentary switch that you depress when it's time to launch. This will yank the timing way back and lock you in at a preset RPM and with the timing yanked and your foot in the gas you'll be building boost like a mofo off the line.

Just don't get too silly with it, things can heat up really quickly.

Newt... sorry for the confusion, is a trigger on the steering wheel, not the crank wheel.

Who is using one on a IIC where I can use to wire it on my car.

Need the info guys, any help!!!

Arturo, the Tuning manual goes into detail about the installation and use of this feature, have you tried using the resource you have at hand?

Thanks,

I'll make a little diagram so you guys can tell me Im on the right track.

Thx

Here it is, let me know guys.

it is a little vague though, for some of us les technical thinking people. i was trying to help arturo over msn...

basically that diagram posted is how i think it should be wired up according to what the manual says...

that 10k resistor should bring the 12v down to an acceptable voltage for the ecu right?

The +12v should read +5v. You get the power from the sensor power output on the ECU. THE yellow/red wires. The 10k resistor is put to ground so when you open the switch it pulls the voltage down to 0. So, with the switch closed you have +5v feeding the Aux input, open you have 0v feeding the Aux input. Aslo keep in mind you have to program in a good chunk of timing to pull when activated or it may seem like it's not working. Start with 20 degrees. Now, this will make things hot because you're essentially shooting flames through your header so don't get to crazy with it. I ususally try not to use mine for more than 4 or 5 seconds at a time. For drag racing I engage it right after both cars are staged.

Yep, Jim put it nicely, that clear things up?

definately does....

pull 5v from ecu, run to switch, run aux wire to switch, and 10k inline resistor. wiring is fun, i dont know why so many people hate it :p

good point on the timing, things do heat up quick, i was going to start out with more to begin with, 30 or 35 deg. i'll start smaller, thanks

You are close, but the resistor is NOT inline, and you want to use the 3.3v voltage tap (TPS+, CLT+ or MAT+) and the resisitor goes from AUX to ground (TPS-).



[TPS+]>----------[N/O Switch contacts]----------->[AUX]

[TPS-]>-----------------------------[10K 1/4w]----->[AUX]


This help out?

bringing this thread back to see if anybody has tried setting up the circuit this way, using the factory clutch switch to enable/disable the system. I've heard of someone doing this with success, just wanted to check my wiring.

I'm pretty sure if you hit the aux-in with 12v instead of 5 it will just rail the input to the max cell (5v) in the tuning software without doing any damage, correct?

Anyway, here's what I was thinking:



In order for this to work the cruise control module would need to be installed and the cruise switch set to the 'on' position, otherwise you'd have to rewire the circuit to feed the factory input to the clutch switch with whatever voltage.

Thoughts?

If I remember right you want to ground the aux in to activate antilag. So you could make a double pole enable switch that gives 5V's when the antilag is off and goes to the clutch switch when enabled. As for the 12V stuff.... not sure how the ECU will like that. I actually think stuff is 3.3V as well on the 034 controller.

Thanks for the reply Preston. If you read TheArchitect's post above mine it seems to indicate the auxin should be grounded when launch control is off (at least thats what I read when I see he is suggesting the use of a normally open switch and the ground is connected to the aux-in side of the switch)?

Correct me if I am wrong.

I am wiring up Anti Lag and I plan to tap off the TPS+ signal and use a normally open switch to connect that signal to the AUX input when the switch is in the normally closed state.

right, but you need that ressistor in there too. the whole point is to feed the aux with voltage from the tps+, then once you hit the switch it grounds and the aux sees less then 1.67v, activating the anti-lag. (at least i think thats how it works)

zerb, thats correct. you hold auxin "high" with the TPS+ so that rev limit 2 is ignored under normal operation and you can set the rpm in that field to your desired launch rpm. then when auxin is brought low (launch control enabled) revlimit2 is respected again and you use the large max retard field on the same page to cause the turbo to spool on the line (basically burning the mixture at nearly the bottom of the 'combustion' stroke so that the flame burns in the EM...

Off topic but where does one get there hands on this Tuning Manul?
I'm about to install the used 1C wasted spark setup i purchesed recently

It's included with all the software packages on the website, or on any CD you may have recieved.

Sorry to bring this back from the dead.......
and correct me if i'm wrong.....I'm thinking of using the anti lag...as a full throttle flat shift buy using a switch on the clutch peddle.. to ground the aux through a 10k resistor...... and a full throttle switch to activate or complete the circuit from the CLT power source
will the 1c pull enough rpm to make this happen? or am i smoking crack again..this would also function as a launch controll if i'm not mistaken...or am i mistaken

you dont need a switch on the throttle, there is no real hurt in letting the launch control stay enabled over the 1/4 mile for the short duration the clutch is depressed during shifts. you dont want to hit the aux in with 12v. use a 5v pullup from the hall vcc.

Great..that will be the next thing i wire in.....
just got it running again after burning the head gasket between cyl 3&4 and wrecking the head....oops
now to finish up part throttle drivability

The thread that will not die!

I can not figure out how to wire launch control with a momentary push button. I can make sense of it with a single pole, double throw (see attached) but I'd like to use the wheel mounted button I got from 034.

What am I missing?

Are you running the 1.02 firmware?

Wiring can be simpler in this case.
