Which 19? At first I was using the 19 auto table and it was a bit much. I found the 19 manual table, it had a bit more timing, and it was more mellow, rolling gurgles, no pops

The 2019 file I have is an auto.

This is what I believe to be a 2020 m6

Do you or does someone else have a version of the 2019+ M6 table in a file that I can copy over? Is there somewhere you can download the spark tables by year by model?

Or is everyone just visually looking at it and overwriting hah

The main differences are in the last 4 rows you can see from the previous picture. But you can check out HP Tuner forum and find a stock file someone has posted. U also have to match or adjust the speed at when dfco comes in or it won't change much with the timing alone.

Here is a stock file I believe from a 2019 automatic I found on HP Tuner forum. HP Tuner forum is the place to be, people are great at sharing information as a community and very helpful.

WOW My tables are nowhere near to even look like the 2017 tables.



That makes me wonder if my car didn't have a custom tune before I bought it :confused0068:



I ended up copying the entire 2019 tables :bonk:. I hope it'll work out in the long run. (I don't even have a custom exhaust or air intake).

Have a 2016 SS with stock cat and no muffler with a 3,5 inch exhaust.
In hptuners, I changed everything till row 7 or so. Popping crazy now. Probably a lil too much when driving through cities. I will make it a bit less at certain speeds. But here is a video for those who wonder how it sounds.

Edit: 17.10.23
have the M6, it behaves different than the automatic. M6 revs are dropping faster than on a torque converter I believe.
Anyways, manuals have different values, obviously not that far negative.
In the video above are the values from the newer automatic models, which are to be honest on manual cars way too much.
Now using M6 2020 settings and its perfect, still decent when u want it and u also can drive in peace when u want to

There are hidden tables that take some effort to uncover that affect burbles too. GM changed these values in the 19+ cars and then again in the 22+ cars.

I was wondering why 23's were popping alot more, that makes sense. I had a 17 ss, wanted more bubbles. Got a 19 zl1, still didn't get the burbles I wanted oof
