Esys can't read all FSC files from ECUs (can only read 1 ECU) while engine is running. But it reads 3 ECUs while its in diagnose mode. So in which mode can I read all the ECUs?  |
You can read all the ecus in diagnose mode or while engine is running, fdl coding is also possible while running except for DME. Running the engine also prevents from draining the battery, it's up to you really.
