I’m having a nightmare with my JB4 and can’t seem to get any answers or replies.
basically I have the Bluetooth kit but the only gauges that display on my phone are the boost and current map.
i can’t scan for error codes either.
so basically my JB4 isn’t getting any info off the obd2 port.
Ive no damage to the obd cable and continuity on each wire.
yes I have got the small 4 pin plug in the right way around
ive tried the latest software and tried some older stuff
ive tried iPhone and iPad and still nothing.
Surely im not the first person to ever have this issue.
any ideas please guys?
