ZL1 1LE full throttle after apex

nighttowl · 09-20-2020, 01:01 PM

When the car first came out I rememmber that GM advertised the car can be tracked in a manner where you could mash the pedal to the floor after the apex and the computer would dole out power to come out of corners faster.

Has anyone done this?

Race mode, dry or sport 1

PTM does a pretty good job of managing the power delivery, but I’m not convinced it’s faster. I’m heading back to the track next week, and plan to turn everything off to see how it compares with Race and S2. I was too chicken to try it last time, but I have more confidence in the car now after a few more days on track.

Tried this in PTM Sport 1 at 0.5 mile track up at Lime Rock. It works, it makes crazy noises, I don't need to do it again

It will also heat up your brakes, because it will apply them as part of the stabiltrack system, so be aware of that also

As I understand it, stability control is turned off in Sport 2 and Race PTM modes. Throttle and e-diff control only. I’ve done 5 track days so far with no brake rear brake issues.

M3bs that is my understanding also

I’ve done mostly Sport 1 on the track and you can definitely feel it limiting the power on exit, as you try to push the car harder.

You can do it easily, doesnt mean its faster.

Yeah, while it does work as advertised, the noise the exhaust makes and the sound of the fuel cut-off just makes the car sound sick, and not in a good way.

Reminds me a car with a fuel injection issue and a need to make a trip to the dealer, lol.

I wish they could make the system not sound so terrible, however it does work.

I never noticed unusual sound in S2 or R, just felt loss of power. Of course, I was usually pretty busy at the time....

I think it sounds kinda neat. I really admire the tech that creates it.

OP, if the engine had a tongue to roll and it could roll it, that would be the sound it makes.

I still don't have the guts to try it... ...there's this little voice in my head saying "what if it doesn't work?"

Find a big, empty parking lot or do an autox. Probably the safest ways to try it.
