Hi Finn Concur with your thinking and understanding. It was a fixed code option for an earlier code version of the EC2 that you requested from Tracy. I did begin years ago to read the assembler code and gave up. My knowledge of the coding is just not high enough. So I’m in the dark when it comes to whats actually happening with my current code and BUSENSOR. Its all there in hardware from engine to EC2 processors but in the code?

In program it appears to set/reset BUSENSOR bit, but I guess only for engine types that support it of which A8 doesn't. :( > > Steve, do you use Mode 5 to toggle BUSENSOR on the EC2? > > Hardware is definitely there.

It sure will be interesting to find out how it determines if primary sensor has failed. Wonder what happens when backup sensor fails and primary is OK. With no other inputs, I don't see how it can work. >> >> >> >> Finn >> >> >> >> On 10/4/2020 3:20 PM, Bobby J.
