What are you using for an OBDII scanner on your JK?

I have jScan, but also the Appcar DiagFCA for PC. Both are very good. but the Appcar DiagFCA can do more models (can do my wifes KL, but jScan doesn't).

Use the recommended or known good BT dongle for jScan

X4 to the JScan app and VGate reader. Turned off TPMS, changed tire size for speedo, and programmed a new key. Trail Mode is sweet too!
