Exclamation No boost after jb4 install on any map. - 09-17-2021, 04:27 PM

I have a 2018 q60s. I got the new jb4 module with fuel control wires pre installed. I've installed everything and I'm getting codes for turbocharger boost sensor circuit bank 1, supercharging pressure sensor, and turbocharger boost sensor circuit bank 1. Any ideas?

Sounds like a bad connection on bank 1 from JB4 to the sensor. Check them and see if anything is loose. If they feel tight and clicked in place, pull it back off and inspect the pins to make sure they are still straight and lined up (and look for any other signs of damage). If all that is good, Try bypassing the JB4 wires and putting it back to stock and see if the CEL clears and the boost is back. BMS may have to send you a new harness if you can narrow the problem down to the JB4.

I have reverted to stock and everything works as it should. No codes.
