I have strange issue with the Black ecu. Pretty much everytime I switch power to the ecu, the logbook states that there has been DBW, MAP and WBO errors. They were not there when I switched the car off last time.
When I reset them and start the car some of the 3 might come again, but if I reset them while the car is running they won’t come up and all of features seem to be working normally.
What could cause this kind of issues? Is there something I could check or test? I know that my battery is not in optimal condition since it reads near or lower than 12V before cranking and looking from the log shortly drops to 9V when cranking the car.
The second issue is the knock control on startup. Might be that I have some wrong settings, but every time I start the car, the knock control picks up knock events even though the Min RPM for knock activation is 2000rpm and the knock engine noise is 5volts for 1000rpm. This can be seen from the log.
I’m running 3.065 ver FW but the issues have been there for a while
