Hi,

Setting the Start RPM to 0 will have the ECU logging constantly.

Hello,

i try that in very first place but says that There is no logging data to retreive. I try to resend file, turn on and off ECU, restart my PC, assure that I can see my air temperature sensor that I setup. But no logging data to retrive.

Of course have logging, lambda, and many other options on my M800. And was running one engine few days a go with of course logging working. Not sure what I am doing wrong.

Thank you
