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.
