Wondering if anyone here running the JB4 on there VN that has AFR issues?
As of lately on initial start up the app gauges will not monitor AFR's, it stays pinned at 14.6. All other gages are working just fine though. Once the car has warmed up a bit i can shut the car off and start it right back up and they work fine. Data logs show everything in working order too.
At one point it through a code P0130 for low voltage upstream O2 sensor. Replaced that and still same issue. Also replaced the fuel harness for the JB4 and still the same issue. Spoke to BMS, they have never ran into this issue before and said to buy a new circuit board problem solved. Well before i throw 200 dollars at a maybe fix. I would like to see if anyone Has run into this issue before or might know how to help out.
I would greatly appreciate it!
