How to launch on boost

[brancky3]

Tried this today but it pulls through after some heavy throttle.




I think this is worth a try. If it works it will solve the burnout and launch problem.

Any idea were to look first for the wire?

There's a fuse for the brake light in the driver's side fuse panel

I think the real win will be interrupting the brake pedal wire with a simple switch.

And another switch for interrupting the "4wd" 20A fuse under the hood for drift/hoonigan mode for us AWDers, eh?

Just sayin'...

i need more detail. This isn’t detailed enough.

I'd actually try to do a bit differently to allow for leaving the fuse panel cover in place. But basically:

• Fuse is removed and replaced by connections to wires (in this diag, a bypass).
• Those wires connect to a switch, placed wherever in the cabin.
  
• On one wire is a housing for the fuse you removed.
  
  
• When the switch is closed, the circuit is complete and you have behavior as normal.
• When open, the circuit is not complete and the AWD is, as I understand it, off. So, time to misbehave.

I'm no expert, however, someone please correct me if I've wandered into the muck.

I am sure he was joking.

It looks good to me! Can't get any more simplistic - if you do, then that person should have a technician do the job.

My apologies if so. My work tends to make me sententious.

Ok guys, im happy to report that this will work. I disconnected the brake pedal switch just to see if it works before doing the switch bypass and it worked. I still wasnt able to get more than 5psi but it would hold forever and i was able to do a burnout as well.

If you want to test it, you need to have the car in drive and pull the ebrake and then disconnect the connector. If you ever leave drive you wont be able to go back until you connect it back because the car needs to see the brake pressed to go into drive or reverse.

Connector is quite easy to reach and disconnect.

It's worth mentioning that pulling the AWD fuse does a LOT.

Disables: "IBU, ECS Unit, AWD (All Wheel Drive) ECM (Electronic Control Module), Smart Cruise Control Module, Auto Transmission Shift Lever Indicator, Console Switch (Front/Upper), Blind-Spot Collision Warning Unit Left Handle side/Right Handle side, Steering Angle Sensor, Steering Tilt & Telescopic Module, MultiFunction Camera Unit, Crash Pad Switch"

:O

Uh... Never mind.

so basically, your telling me to wire a switch through the fuse box to disable AWD, and another one to let me do a burnout... Man i might have to try this.......

I know. There went Saturday...

But!
Does simply pulling the brake light fuse disable brake signal to ECU (versus "cutting a switch in" to the brake pedal switch wire)?
Or would cutting in a switch simply be easier?

Either way I would want a spring-loaded momentary switch (have to "hold" switch open/interrupt the circuit) to prevent me from inadvertently forgetting and not having brake lights :O

I think tapping the brake pedal connector is better. It will be easier to route the switch to the driver and will not affect other systems in the car. We just need to figure out the correct wire that is going to the ECU and add a switch there.

There are five wires. Blue, orange, black and two green.

Anybody have any idea which to tap?

How would that be easier? The brake light fuse should be all you need to disconnect (at least from past experiences)

Blue because is my favorite color.

Depends were the fuse is and if the fuse is only for the lamp or other systems that you dont want to turn off.

Possibly relevant fuses, additional circuits affected.

Time to start pulling!

I hope its the Stop Lamp fuse not the Module 3.

What does IBU stand for? All I could find online is IBU = International Bitterness Unit for the Beer Association
