Port Injection Issues

[Idratherbesurfing]

Yo guys heres a list of things im running. Jb4/mhd stack, Full Fuelit system, bms jb4 pi controller.

My issue is port injection not flowing at all. The wiring is set up correct so it seems as though it's a menu setup issue. I bought this jb4 used so the previous owner may have something messed up in the settings. Menu 8 is set to zero, meth trigger is set to 1, and the car doesn't have a two step relay. Any suggestions?

Am I only installing the chip or the wire as well?

Just the chip to fix the PI issue, hopefully.

Did you ever got this resolved?? I went through the exact same issue. Meth signal was returning 0. My JB4 was a ver1 so I bought the chip but same deal... then ordered a brand new JB4 board ver5, but still having the issue. I rechecked all the wires, power and grounds with a multimeter and also made sure both yellow and white cables are hooked into the DB connector. Stuck in here.
