2015+ pops/bangs

[Alex14SS]

Hello all!
So I?m more familiar with ford & GM & Infiniti when it comes to getting pops & bangs but it seems like these like to buck up & down when you go and add the same settings. Is there something that I?m missing that?s making the car buck up & down rather than just drop the rpm?s down?


Car: Hellcat
disabled DFCO
Disabled cot
Min spark -30
First 2 lines of spark tables from 2,500k to 5k are at -25

Any help will be appreciated!

Post the tune, it will be easier.

Part throttle and MBT should be the same in the range.

Pass the file, maybe you're missing tables to move

Hopefully you guys can tell me where I'm missing but I think I found it while taking these SS... but it bucks when you pull timing & it wont drop the RPMs down, it'll flutter

Update: tried to remove timing from most tables and still bucks up & down. Any suggestions? Need the rpms to fall down not stay stuck when I pull timing.

Test the file, you've already done all this apparently but try it and in case everything you've done doesn't work for you, you might have problems with the cam sensor

This worked!!

So the problem was that you need to have ALL tables exactly the same, you can't be off even by a little bit as the ECU will fight against itself and start bucking really hard. I know on GM you can go by octane and by other timing differences per octane but on this platform, it seems like it all needs to be exactly the same so -15 for example needs to reflect everywhere or it won't get the results you want, it'll start bucking hard. Hope that helps someone & thanks for the help Josue!
