Can anyone help? I was doing a live data log when i turned on my ac. The diablo screen went dark and the dash beeped with service engine soon and fuel gauge malfunction, almost like it does when writing a tune on it. I unplugged it and shut off car replugged it in and when it prompts me to turn ignition key to on position it doesn't read that its on. I cant look at trouble codes, live data or modify tune now. Did i screw up the tuner by turning the ac on or can it be reset some how or ,ughh, mess up my computer?

Check your ecm fuses. Have that issue sometimes with tech 2. Usually blown fuse not powering up the proper pin.

where are the ecm fuses located? I checked under the steering wheel and under hood on the fender. none are listed as ecm.
