EMS-Pro Showing High Voltage
Hi, new to this. I bought a EMS-Pro (MS1/Extra rev 029w) a few years ago and just getting around to playing with it now. I have been bench testing it and when hooked up to a regular 12v battery it displays a voltage reading of 22volts in TunerStudio. The Fuel Pump light also flashes in the unit. After one Burn to ECU it was working, reading a normal voltage, no light flashing, able to calibrate TPS, temperature senders reading correct, but when I unhooked the battery to the ECU and reconnected it, I was back to the same problems. Any suggestions as to what could be causing this? Hardware or Tune? Any help is greatly appreciated. Thanks.
