HUMMER H2 Crackle, Pops
Hello everyone,
I have read a lot of threads on how to do pops and bangs but not sure what to do exactly.
I have 04 H2 LQ4 6.0 Cats removed with Borla Exhaust
Below is the Engine->Fuel Tab in my VCM editor:
Engine-Spark-Advance.png
Where exactly shall I click and what values I have to change in order to get moderate pops?
I know I shall change spark timing but I don't want to mess up with incorrect values in incorrect locations.
Thanks in advance.

Crackles and pops don't come from your fuel table, they come from reduced timing in the high rpm/low load tables (The first 3 rows from say 2000 up to around 4000 to 4500 rpm)..... Reduce the timing in that area down to around 10 degrees. It will probably pop a lot there. Add timing for less pops

I will send you the tune so I can compare it with the one I have in order to tell the differences.
