I have a 1988 C1500 with 1227747 ECU. I have a Red Devil River ALDL bluetooth device and ALDLDroid installed on my tablet. The bluetooth device powers up and I am able to connect to it with ALDLDroid but all I get is a msg that says Connected/waiting for ECU data. The bluetooth device blinks about every second like it is sending data, I just don't get any. I used the Tunerpro ADX file that was provided by Red Devil River. So what am I missing??? Any help would be appreciated.
