We're definitely at the limit of AWD traction at this point, likely better rear tires will be the next step to move things forward at the track.

Ok I have a 2019 Stinger GT2 RWD. What would be the proper method of operation using this mod? Is it sport mode TC off or comfort TC off or...? what is the best suggested way people are having success with? Thanks.

Without tires not sure it's really going to be that useful to RWD cars. Launch mode is disabled with the switch active and you brake boost off the line.

My one launch at the track with full throttle and 10+ PSI resulted in a bit of spin followed by a 2 second throttle cut. ECU didn't like something. My car always cuts throttle after 1 second of spinning but this was different. Less spin and longer cut.
Would it benefit AWD users to disable the AWD when using this mod? Would this eliminate the risk of damaging the transfer case? It's as simple as pulling the fuse right?

Would defeat the purpose... RWD = spin city.

Turns out it wasn't the transfer case. RWD guys not off the hook yet. Stay tuned.

Why do that though? If you make the car launch harder then disable awd your just going to loose all your traction.

Sounds his dealer sent him home with the car and said nothing was actually wrong... Probably a broken trans or diff mount IMHO.

Need some help here Terry, Ive done about 25+ launches with the BMS switch on and off the track and ive noticed something peculiar, Switch On to disable the break signal, AWD, car set to sport mode, traction control & stability control off: set to launch and anything over 2500 RPM launches the car with wheel spin out for the rear tires and some front: then the computer cuts in immediately disables throttle, maybe boost aswell to stop the wheel spin for about a second or two then its all good again pulling 106, 107MPH traps @ 13.8 to 14 seconds in the 1/4. (with some pretty horrid 60' times like 2.6, 2.8). Im stumped why the ECU is kicking in more frequent ive been able to repeat this launch behavior 4 times now.

That will not be your ECU. That is the TCU intervening.

Mine cuts throttle if i spin for 1 second in rwd mode just punching it, even at 30 mph.
Break snip it will cut on a hard launch as well with little to no spin.

Has anyone traced the wire that needs to be cut? I'm just looking for a different/more inconspicuous spot to make the cut rather than right next to ecu...

Good to see another GT2 AWD is getting similar results to me. If I launch when the "A" light is flashing on the dash, my full boost mode, the throttle will cut on the track even with little to no wheel spin. (aggressive launch lots of grip that you couldn't replicate on the street)
Right when you flip the switch, do you ever get a less aggressive launch when the "A" light is not flashing? That mode is actually quite useful 1.74 60s and wont spin the tires.
I thought about trying an E0 aggressive mode launch to see if its a fueling issue but do suspect the TCU is likely the cause.

Couldn't tell you. But the switch does what it does. If it's not working for your car then there isn't any other way to achieve the same effect that I'm aware of.
