E46 323Ci MS42 pops and bangs/crackle help needed

[e46ms42]

Hi guys,

I need some help with a tune ive been trying to do on my E46 323Ci.
I tried to do an exhaust popping mod using the data shown on the MS4x wiki, however the only thing it did was turn on my check engine light :D .
Running stock headers and Magnaflow rear muffler, planning on going catless next year.
Would be nice if someone could help me get some nice pops going with the A/C off. Original file attached down below.
I know some people dont like it, and i also know that its not good for my engine so please refrain from comments of that sort, thanks.

[e46ms42]

Hey man, I have been trying to do the checksum correction with MS4x flasher but its giving me this error: Failed to correct the bootloader checksum.
Do you have any idea what it could be? Im relatively new to flashing.
