Checked what map I was in and the JB4 said "invalid nap selection" and it magically ended up on Map 1. But when I checked the logs while this was happening it says I was still in Map 6. I had to pull over, restart the car, clear the codes, and switch back to Map 6.

Anyone got any thoughts on this?

Terry any help with this?

Happened again on Friday. This time I was in 5th at 80mph part throttle. Tried to pass someone and got Drivetrain Malfunction, gas pedal did nothing, and JB4 went from Map 6 to Map 1. Why is the JB4 switching to Map 1? Attached are two logs after the map switch.
