I have reviewed your log [v3.3_u010045-2018.06.25-21.45.36_31.vemslog], you are not getting lambda reading beacause there is still a problem with the heater and pump control as i explained before (but it seems to have gotten worse now, Ri is not measuring at all).

Hello Peter,

I have reviewed your wbo2 warmup log, there is indeed a problem there. Both the Ri and Nerst Dc measurement are oscillating around target not stable like needed and control actuation seems to act in bang-bang fashion.

To rule out any firmware problem (you are running 1.2.33 which is marked internal, not even testing; see GenBoard/UnderDevelopment/FirmwareChanges) i would recommend you upgrade firmware to the latest released which is 1.2.38.

Could you take another log of wbo2 calibration using this firmware ? Thanks! I'll review and provide hints on next steps after.

Best regards,

Dave

Hello Peter,

To get an idea whats going on, could you make a vemslog of wbo2 calibration running (no need to take sensor out of the exhaust, just make sure the sensor is cold when starting the calibration) after starting let the log run for at least 5 minutes.

Please link the log here so i can review, we'll work from there; Thanks!

Best regards, Dave

Problem solved

Serial connection

I replaced max232 and it is now working aging.

Thank you for great support

Need Help: ECU runs but no serial connection (MAX232 problem suspected if wiring has good ground and no intermittent RX/TX problem).

End user had problems connecting to ecu.

We have tested on 5 pc and many usb to serial connectors.

Problem started as a small issue but got worse over the time and now we have total lost any kind of connection.

ECU 17956

The ecu is running nice in the testbench but no communications.

You can measure and check outside connection and disassemble if that does not solve. Do you have a spare ST232D or MAX232 (SOIC16) IC already ?

I really need to get his car up and running so please help.
