v3/19769 sent for repair (2021-10-26). ECU communicates reliably, and no issue with inputs or outputs was found.
- "fuel injector activated (not for a short time)"
- injector ouputs and all other outputs activate as they should. Tested with test config.
Most likely the problem is caused by configuration
- however, more details about the engine and harness are needed so we can give tailored advice related to configuration.
See [2021-10-25.vemscfg Config file] (most likely problematic):
ECU communicates without any problem with good USB-RS232 adapter
Most likely cause of any comm-problem is bad USB-RS232 adapter, or windows driver (or cable or USB port or similar) problem
- "sometimes ECU cannot be reached" => with good cable: works 100% reliably
- "some values couldn't be read out or implausible"
- perhaps related to USB problem. Otherwise some example vemslog would be interesting, with exact examples.
Hello Marcell,
i sent you an overview of the wiring with the ECU. When the control unit is supplied with power, the fuel infectors were activated 100% immediately for a short time and there was a real blow to the injection rail. Another problem was that the injection maps could be changed in the software, but the ECU did not accept or process them. This will cause too much fuel to be injected.
Then we tried a ECU from a friend and it worked perfectly.
Is it possible that you still change the mainboard and I will pay for the change?
