cut and spliced in a switch

Man...there has to be another way

I think there is. You should be able to de-pin the brake wire from the nearest harness connector - but you'd need to be able to find an OEM equivalent harness pin to attach back into its place in the harness plug. After that you can custom wire up your switch the way you want it. If/when you want to undo your changes, you can bring it all back to stock without any damage.

I don't know where you'd get wiring harness pins, though, other than the junkyard from a stinger or probably some other Hyundai or Kia car. I'm sure there's a place online you can get new ones..

i wish there was another way myself but i feel until someone completely cracks the ecu open this is what we are gonna get

 

[Vortex951]

but at this point this point i might as well get the wmi also lmao

 

[CoconutRob]

well i think i might be the first g70 owner with the burger burnout switch. needless to say i can smoke the tires instantly now going testing with a few buddies this weekend will report back on if this helps get the launch nailed since i can properly warm up the tires now.

So what exactly does the switch do and what are the I'll effects of doing this. I read somewhere about holding up the emergency brake switch and launching , is this the same concept? (Not sure if the brake thing works , too scared to try.

So I’ve tried that e brake idea and got nowhere with it. I haven’t heard of any rwd problems cause once you start spinning the tires that’s all that happens. When you spin the tires on the awd cars I heard they try to transfer power forward and that’s where it goes bad. Only if you hold it to long tho. But my car did build up to about 10psi of boost incredibly fast. Probably less than 1 second is all it took. So it will be a fine line to get this launch down for me since I’m going to want to try and get off the line around 5-6 psi being rwd. After a good burnout and rear tires at about 18 psi I’m hoping I’ll have a chance of it hooking. If it doesn’t I’ll have to run the switch into the cab. Do my burnout. Then flip it back for normal launch control. Time will tell how it’s going to work out

Not exactly what I was hoping for but best stats my car has gotten yet. Had a bit a wheel hop all the way through first gear so I feel a better et is just a matter of time and getting the correct launch figured out. Track was at 2000 ft elevation and da was 3600ish Temp was 55 degrees and tons of cars so not being able to do a burn out hurt a lot when you have to wait almost two hours for a pass

That's a terrible DA. Your car would be really fast near sea level in a cold weather. My DA is under sea level right now. Free power.

Even with a bad DA, you could improve to mid 12s if you get 0-60ft under 2.0

Ya another forum member and myself have talked about making a trip to Cali from Vegas but unfortunately it seems the days we could actually run on a track are mid week so that won’t work for us. I’ll stick to my horrible da for now and hope I can make improvements. I’ll be using my draggy this coming Saturday to hopefully see if the newest mod helps me get off the line quicker and keep traction

That’s like me here in Phoenix. I’m heading to the Oregon coast this summer. I’ll get some runs in and see what I can pull.

I might plan to try and hit the 1/2 mile event in Cali that happens around October. Would be a super cool experience for sure

sea level im for sure he break 11's

past experience from running in California compare to Las Vegas we were hitting times a half sec to a whole sec faster in California.

This is different from the e-brake method...which tricks the car into giving you a bit more RPM at launch.

Here...you are clipping one of the wires at the ECU. This wire is what tells the car you are holding the brake for a launch...thus maxing out the RPM’s at 2,200.

With this snipped...there is no RPM limit!!!! Yeah...fme...crazy. So you can launch at 5k RPM if you want. Experience the car at it’s finest.

Obviously...zero damage control. Don’t over rev...and don’t hold it too long.

With my JB4 on Map 3 with 99 octane...3.6 seconds is probably possible. Probably on par with the AF Gulia Q.

Now all we need is for Todd to make some adapters and sell on the forum. Lol but serious, no just kidding NOT REALLY

 

[Toddasaurus]

No way. Brake snip is too dangerous! I think it would be better to wait for an ECU flash that gives a little more boost during LC and leave it at that.

Also, Terry said that he might be able to let the car build some boost during LC now that he has the EWG figured out. Even so, when I was playing around with launch control a few days ago my JB4 said that the wastegates were closed during launch mode anyway, so.... I don't know if it would make any difference.... Maybe it's the diverter valves, staying open when powerbraking...

 

[Beefer]

^ I agree it's too dangerous. May be a lot of fun and crazy fast...but than that one time...you F up the car big time.

All we need is to be able to launch at 3k RPM...instead of 2,200 RPM. That would be the sweet spot I think without ruining anything. At least somewhere under 3,500 RPM anyway.

I haven't used LC in like 6 months...does nothing for me.

looks like off the brake switch if. We could find the right connectors.
Would appear the number 2 pin to the IBU (integrated body unit which I see Genesis calls the ECM as it’s all one unit now. This may be the same wire. Worth a look.

Agreed, definitely worth a look. If it's the same wire, it could be easier to de-pin and wire up a switch, all while also being easier to undo things without any trace.

Not sure if there is a connector in-between this and the ECU harness. If not, the wire color should be the same. In Terry's Stinger it's a green/black wire, apparently...

I’m thinking the green / black wire is the IBU wire on the brake switch. If it is would be great if we could find the right connectors and make a jumper connector like we did with the 02 sensors.
