Default NLS & 2 Step Problem - 09-13-2019, 08:35 PM

Finally got my JB4 and backend flash running somewhat smooth. Was super excited for 2 step and NLS but can't seem to get it to work. For the 2 step it does do ignition cut and limit the revs to whatever I set it too. It does seem to bounce slower then what I see in the videos and also limits it a few hundred rpms higher then what I set it too. It sounds like it cuts ignition and smells like it's dumping fuel in. JB4 tells me I'm making about 2lbs of boost only and also the loud backfired and bangs does not happen no matter how long I 2 step for. I've tried all the rev ranges from 2k to 6k and every single time I don't backfire, build much boost and also bog every launch. I've made sure to have the lastest mhd bef and jb4 firmware update. Wiring seems all good. Also, with no lift shift it doesn't work and cut ignition with the clutch in. Every time I test it, I just end up clutch kicking.

Not sure if I log of 2 step would help but I can post that. Amy help would be much appreciated!

Did you double check wiring?

Usually when it doesn’t work at all it’s either a wiring issue or something is loose
