Summary of change:
Short description of the project I'm working on. Is it a lucchini prototype chassis with a 3.0L v6 Busso 24v engine V3 ecu bought early 2021 only crank trigger 60-2 with VR sensor no cam sensor 3 injector outputs and 3 ignition output used no ignition drivers, because coils are driven by an amplifier tps sensor air and engine temp sensors very simple. the unit worked perfectly for last month, last week, 5 august 2021 while I was tuning the fuel map on chassis dyno. after a restart, engine flooded and injectors stuck open all the config file of the ecu was blank when I try to upload my file to the ecu, at the end, verify is false same problem if I try to update firmware. it seems that the memory can,t be written anymore. as we had a race 2 days later, I took another V3 ecu from another car so we could go to the race, and the car worked fine all race week end. could I test something on the board by myself ? I need to have both cars running in 3 weeks. thank you for your help
