It seems to be working fine. I haven't had any CEL or fault codes. I can run the Mode 6 "Test Results" and get some readings, there are 2 sectores that read "not ok" but I don't know what they are, everything seems to be O2 sensors. 90% of the time it syncs and works no poblem, but 1x or 2x it wouldn't connect to ECU, don't know cause, only happened 1x or 2x. But the Adapter will stay on if plugged in unless you flip a small switch next to the chord, kinda of annoying placement. I say that because I fear battery draining and being dead. The chord is exceptionally long, I could probably run it anywhere in the car, would be pointless though.
