It's an update to the CCM.

Does anybody know of a way to get this without bringing my car to the dealership. Can I for a lack of a better word Thumbdrive the data and the through the obd port? I have not a clue about this. I prepare to go back to my car and Thailand (provided it's still there) in April.

I understand it's another one of those dealer-only installs. That is, unless HPT has cracked the lock on the CCM.

I sold my car in October. But I still remember the pucker factor attached to this wiggle. The tires on my car were MPS4s, always properly inflated and I still had the wiggle.
My car was a 1LE so I already had the solid suspension components in the back.

I don’t miss that wiggle one bit !!

Funny. Mine on 4S wiggles often but I've grown used to it. I'm chasing the eLSD update for drag strip purposes.

DangerZL1 · 01-31-2022, 01:34 PM

Does the eLSD update apply to 21 or 22s?

It appears to apply to 2019 and later, https://gm-techlink.com/?p=11978

It appears to only work if you turn off traction control and ESC.

I’ve been in the camp that most of these cars need a proper alignment, those TTY bolts replaced or the rear toe arms swapped along with a carrier bushing set.

IneedAZ did the update. It’s talked about in this thread.

Here's some info and a link to dealers who can supposedly perform this update https://www.lsxmag.com/news/make-you...d-calibration/

Interesting, its not the drag update? Would love to know a part number for flash number since I attempted to call our local dealer and attempted to explain this and they 0 clue what i was talking about. Shame I'm willing to try it to see if it removed some of the wiggle. Nobody likes the damn wiggle

Hello everyone. I haven't been here at this forum for some time now, due to many life changing circumstances.
Unfortunately I also have had that wiggle problem from day one with my 2019 zl1.
Mps4s all around. Its quite scary when I just want to have a little fun on the highway. It really sucks actually for the bucks$ spent on a performance ride im proud to show. Many times that wiggle made me let off the gas.
It takes away that fun part of driving it!
Embarrassing?
Hope you all stay safe!

Have you done the cradle lock outs yet? If not I would, can't believe they made that big of a different but they did. If I would to do again I'd purchase the solids and spend the time needed to drop the whole subframe down and do it since I beat they help even more so.

No,I have not.
I think it's ridiculous that you have to buy aftermarket parts and make changes just to have stability and feel safe in a factory built HP automobile. Especially with today's advanced technologies. And for the $ spent on purchasing it,should at least not have this problem. Or a written solution, OR explaining that you cannot do
the WOT, pertaining to this problem. IMHO ,
Im not saying im correct. I just don't get it.I am smart enough to know what not to do. I still have fun with my Zl1.
