This would be only accessible through hptuners? The last time I used tuning software was with my tactrix cable & ecuflash from the evo days...

Yes HPtuners and EFI live are the only 2 consumer tuning/scanning software platforms worth a shit for GM.

What in the hell is with all this fascination over popping it sounds like XXXX

I want to completely eliminate it, nothing sounds better than a clean snarl on decel.

So i decided to finally disable the dfco to see how it sounded. But my screen looka much different than the one shown, does anyone know why? Im a 17, and dont want to mess with the timing.

Looks like you’re in basic view. Go to edit select view and than select advanced.

Oh good call, that was it, I changed both rpms to 8k and writing the file now. Thankyou for your help, as always. Fingers crossed it works and i didnt mess anything up

You’re welcome! I’d bet 99.9 to 1 that you’ll have no issues.:happy0180:

You are correct, it worked perfectly! Im gonna give it a week, but im not sure if i like it. I thought it would pop more, buts its more of a gurgle.

So, was it worth it? Any feedback?

I’m with you. If anything I want to get it tuned to remove it.

He can certainly help you if you get stuck or are afraid to mess with the tables displayed above.

So I am planning to modify the min spark tables by doing the following: Instead of copying-pasting the whole top 3 rows of the 2019 table, I will reduce the timing in the Minimum Spark Base and Long Term to 5 degrees in the .04, .08 and .12 rows, as this is where I want the pops on decel. If 5 degrees of timing makes the popping rather aggressive, I will increase the timing values from there to fine tune the amount of pops and crackles.

This is what I will do:

Engine>Spark>Minimum Spark> Base and Long Term (Both tables)

First I will change 0.04 to 0.12 airmass rows by 2000 to 3100 columns to 5.00. I will go higher or lower in the RPM to suit my needs and also go lower or higher with the number to make more or less aggressive pops respectively. I 've been told not to go over 0.12 airmass rows.

I will try with DFCO enabled and then disabled, to see how it sounds and if disabling it affects drivability, deceleration and fuel consumption (not that I care). I will disable as geaux_tigerss suggested in post #23.

By the way, does anyone have the file in the first post of this thread? The link is not functional anymore. Thanks!

QFT!!!:happy0180:

What are you guys using to tune? I'm new to this and would love to get into it
Currently running straight through mufflers and a custom fabricated H-pipe and I'm getting wonderful gurgles on a stock tune, but I would love for them to be louder:smiling1:
