I bought the p version that comes with a j2534 toll. Dont like it so i bought the wdi , or wireless diag interface.got a good price on it , when i initialize it to my 908 it works for bout 10 mins then just stops communicating. I only have 1 istalled and paired with my 908. I have to reboot the 908 to get comms back. same on all vehicles. Anyone else drop outs with the wdi?
