You might have an older board and newer chip in it. Does your chip has all the pins, or is one missing?

something is definitely not installed right since when its on map 0 everything works fine but it only starts to give you a code when you select other maps. check all your wires and harnesses. you should email terry for a quick response and solution

absolutely correct because when u r on map 0, the JB3 is bypassed completely and you are totally stock.
... if you installed the CHIP yourself, did you have the small notch in the chip facing the right direction ??

Sounds like a bad install..Should be a simple fix, contact Terry, via email or phone and you should be good to go soon.

If OP had it installed wrong, wouldn't he also get an error on map 0? I know map 0 is stock settings, but everything still goes to bypass through the JB unit, no? I'm not a tech, so I might be wrong...
