i have had the gauge for about a year now but recently when i go to plug the gauge into my obd2 port and than start the car the, gauge goes to start up and than when it goes to scan the ecu the needles on the dash go alll the way to 0 and the car flashes messages such as power steering and low fuel on the die and the car is shut off. it does the same thing if i plug the gauge in when off.
i noticed in a old thread this happend to some one else.
the gauge worked fine about a month ago. i have had it unpligged the majority of the time. so i dont know if bumping into the obd2 plug with my foot may have messed it up.
aeroforce said mail it back and they will check it out.

anyone else experience this problem?
