Some of the adapters can be a bit hit-or-miss. 1.4.58/59 was a bad couple of versions which had an issue with headers (the bits I was working on for trying to get your KR working, which is a little difficult without a vehicle to test on

)
1.4.60 should be good though, and an easy way to tell if your adapter has 'issues' is to let it connect and show data for a short time (a couple of minutes) and then go to the adapter information screen. If you are on the latest version, and "Error Count" reading is above 0, then your adapter has issues and may be intermittent in operation. (The entire point of the Adapter Error Count is to help users identify when they have a faulty unit, there are a lot of clone adapters which have issues!)
Here's a list of current faults with the clone adapters:
* Some adapters don't talk reliably between their internal bluetooth module and OBD2 chip, this usually results in unknown command responses (which are picked up by the adapter error rate display in the info screen)
* Sometimes the bluetooth module in the clone adapter can die. It will just go 'deaf' so Torque/the phone won't be able to find it over bluetooth again. Dead adapter (even though the lights light up)
* Some adapters wont work on slightly older Fords because the J1850-PWM protocol on them has a fault (most likely at hardware) but they will work on any other vehicle not using that protocol (CAN, ISO, VPW, etc) perfectly fine.
Those are the main ones that people hit (then unfortunately blame the app, which is a bit fustrating

)
I've had some KR debugs back, thank you.
A little progress has been made on this and the ECU is responding to the PID instead of ignoring the request, though it is responding with an 'invalid subcommand' (on a '98 GP's) which means that 2211A6 is unsupported on that year, or that KR is on another PID for that age of vehicle.
Do you know of anyone which had KR working on any other scanner type for this year of GP as I'm not sure if the PID (at least for this year of GP) is correct. Still haven't had a KR debug from anyone with a newer GP yet though which should be interesting!
Thanks,
Ian
