I don't know why I didn't see this earlier but I think this question has been asked a few times on here.

As you found out, the only reprogramming a ZL1 can get is the drag calibration for the eLSD. The ZL1 nor ZL1 1LE gets a autocross calibration. The tune you're probably hearing about is the one for the SS 1LE. It's a more refined calibration that the SS 1LE already has.

I read a thread about someone who did a comparison on an SS with and without the calibration. It was noticeable but times were the same and it's something that most drivers won't notice.

There was another user that swore that a GM engineer told him, personally, that the ZL1 can get an autocross tune. Never heard anymore from him about this.

Current document says 2019+ on the bottom of it, however it also says camaro SS 1LE

I'm going to try to do it on mine later this week.

Sometime in September of 2020.

I picked up a eLSD chasis control module from a totaled out ZL1 1LE M6 and will see if there is any difference from my ZL1 A10. Does anyone know if there is a difference between a ZL1 1LE M6 and a ZL1 A10?

I don’t know but this should be interesting. Hopefully it works in your favour.
