test your Foxwell on another OBD port, or with extra supplied power

I already used my warranty, so I don't want to risk it, know I'm paranoid, but the scanner wasn't cheap and was a gift for my dad.

I have yet to check the pins, but if the other scanner connects, should I even bother? Regardless were most likely changing the ECU.
Have you tried your Foxwell on another car? Even if your Foxwell's software doesn't cover that car, the generic OBD should work.

Another thing, if the supplied voltage on your BMW's OBD port is too low, then the Foxwell might act up...my NT510 Elite really doesn't like low voltage (under 12.2v), so I never use mine unless I'm running the engine, or have a charger/maintainer hooked up.

I prefer using my Solar/Pro Logix 2320 (20 amp) that has a "stable power supply" feature, that maintains a constant 20 amps so my Foxwell never acts up, anymore. Of course, the 20 amps wouldn't be enough for coding later model X's, with more modules than my early E53, but I won't be coding anyway.
