MHD Flasher "Cannoct reach ECU"

ChadwickBost · 08-04-2015, 06:38 PM

Car is cranking, but wont start. Cannot reach ECU.

I started a flash and it shortly said that it could not erase memory.
Now it wont find my ECU so I can flash to stock or anything.

Anyone have a clue?

Did you use a charger with a flash mode that supplies a constant voltage?

Wasn't on a charger, I had just connected

Useing a JB4 in conjunction? You need to got to Map 0 on JB4 in order to detect cable and load maps.

I got it. Finicky cord? maybe. I unplugged and plugged, made sure my ignition was all of the way on before plugging in device. Loading new tune now.
