I installed a Scanmaster G and ALDLDROID App. All were running great until today. The App started giving me weird Data readings. The Scanmaster readings appeared to be normal and coincided with my gauges. At idle the ALDLDROID showed RPM anywhere from 2500 to 4300. Most of the other reading were off too. I have reset the App, re installed the App, reset the bluetooth connection with the Scanmaster and everything else that I could think of. The App shows pairing with the Scanmaster but I'm not sure that the ScanMaster is transmitting the data. I noticed that a message flashes periodically on the bottom of the APP screen "no response from the ECU". I'm running out of options that I can think of. Anyone have anything else that I haven't tried? The Apps author is stumped and thinks it may be a faulty Scanmaster unit
