- Your ECU is in good condition.
-DTV is the same on banks and is characteristic for engine idling but evolution of DTV isn’t performed by ECU at idle… DTV is different parameter than longFT. I still think, that your FT is probably positive. How strongly positive? I don’t know. No data from you...
-You will analyze of FT evolution of your engine or you will wait for others faults from ECU.
-You didn't give me any data from ECU for analysis and you didn’t calculate engine FT. Thus, I can’t help you with this. Sorry.
