I am having a problem with a car using a motec m880 ecu.
After accidentally changing the firmware to an older version the car doesn’t start anymore.
Somebody an idea of the calibration data is lost ? is it maybe helpful to change the firmware again to its original version ?
Typically a downgrade of the firmware will result in a loss of data as the conversion tools are only designed to work for upgrading. Do you have a copy of the configuration that was on the ECU before the downgrade was done?
Thanks for the information Stephen. No I don’t have a copy of the configuration data
Do you have any old logged data? (maybe from the previous owner?) -- the configuration will be found the .LD file. Use the "View Device Config..." feature in I2.
I have got no logged data, but I think I can get some data from the previous owner.
Thanks for the help.
