Hey guys, so I'm not sure if any of you guys saw my other thread about my car being fbo with jb4 and it's not even moving and misfiring. Does anyone know if that couple be affected because I have a pkk2? Will the jb4 just override that?? Please let me know, thank you.

That's an interesting question. I know that the 335is has to run special settings since it comes with the PPK tune with overboost. Have you tried shooting Terry an email?

I had asked on N54 and one of the BMS staff replied the JB4 should work with the PPK.

That didn't instill a great deal of confidence, so I'm trying the Cobb AP first

If it is misfiring have you checked your spark plugs? If they are old or not gapped to .022-.028 you will get misfires. Have you taken the jb4 off to confirm that it is causing the problem?
