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
