Throttle cut when braking.

370Zociety_ · 04-29-2022, 10:38 PM

So I see a lot of different posts for how to fix this but non seem to work for my 2019 Z, I don't know if it being a 6M or heritage edition changes anything or if its cause of the year, but most simple tricks wont work. To explain better, every time I put my foot on the brake, I lose all throttle, the throttle wont open while brakes are applied. Has anyone with a newer 370 found a work around for this?

We can fix it with an Uprev tune

ive heard of the uprev tune any specifics to it or just as simple as plug it in?

Its a custom tune for your ECU, you can either get tuned in person at a shop with a dyno or remotely over email based on datalogs you record while driving. Makes a big difference

All you need to do is cut the brake signal wire going into the ECU.

Easiest solution is to pull the STOP LAMP fuse in the driver (LH) footwell. Just don't do it on the street because you won't have any brake lights with the fuse out.

Yeah that trick doesn’t work for either anything above 2015 or 2017, but I’ve tried that and doesn’t change anything

+1 you'd have some serious liability issues if you got in an accident after doing this on the street
