    Thank you very much. I was able to adjust the table and it definitely pops now. I have one question tho, right now it only pop once u get off throttle. Is there anything that could be adjusted that would allow it to pop just on decel like the 19s do. For example if you were to downshift.

    My 17 used to pop and bang real hard on downshifts without adjusting for it. Technically the same thing should work in the areas of downshifting but I haven't tested if it affects drive-ability. You will need to datalog the car when going through the downshifts and see what torque mangement advance is doing and reference against the cells in the areas of the same tables you adjusted. Also, if when you're downshifting the RPM's exceed the areas in the minimum spark table that you've adjusted, you will need to lower them for the higher RPM ranges too.

    I put my entire .12 and lower to 5 degrees once and the car sounded like a machine gun on decel and downshift at any RPM. It was so obnoxious I had to pull over and adjust the tune.
    I've tuned a few things...

    Is there anything like the GenIVs DFCO Delay to define a certain time when all DFCO conditions are met, before it will shut off the fuel?

    Hi together! Im a totaly newby in using HPTuners and I hope you can help me to change my DFCO settings.
    I changed the Base and Long Term tabels in the minimum Spark Tab and now I dont know whats a good way to disable DFCO (disable over high ECT maybe, but I dont know if this is a good way).

    I have a 2017 Camaro V8 SS 1LT 6MT and want more or minimal the same pops and crackels on decel like when the engine is cold.
    Additionally I'd like to have some stronger pops and crackels only when I am in Trackmode, pushing a button / go into the Competition Mode. Is this possible?

    Thanks in advance for your help!

    You need to leave DFCO enabled and at stock values. Also, you cant have factory cats on the car and expect much in the way of pops and crackles. #1) 4 cats will negate much of it. #2) The ceramic based cats cant take the abuse for too long and may fail/shatter etc. IF you want pops and bangs you need to lower the min value to 5 degrees every RPM you want them and then you can blend the values to increase as you dont need 5 degrees at high rpms for pops. I used to have mine scaled from 5 degrees at 1200 RPM to 12 degrees at 5000 RPM. But I also didn't have factory cats. That would have destroyed them.
