After making my post this morning, I sat down with a sheet of paper and really tried to wrap my mind around the issue at hand.
I went back through the scope buffer that I recorded and made a table of the Positive Duty Cycle values and the average voltage levels between the rulers.
To whomever may come looking for this information later, let me make a few suggestions before I provide the solution:
-
Data is your friend.
- I would never have found the answer without collecting the actual information I needed to make this calibration. That is because the behavior is not obvious.
-
Do not “phone it in.”
- I pulled the pedal off of the vehicle yesterday when I realized that it would be best for me to verify the pedal behavior independent of the wiring and the EMU. Eliminating the possibility of a wiring fault or voltage issue in the vehicle helped me validate the behavior.
-
Take a freaking break and come back to it. I did not but I am about to. This has been a rigorous test of my skills, patience and resolve.
So, the answer was pretty simple. The values I gave in the first post are all inverted. This goes back to point #2 above. By taking the pedal out and getting situated where I could properly control the input and output of the pedal, I was able to obtain much better information. One of the ways I did that was setting up multiple measurement scenarios in the Pico software.
While I was looking for (and recording) “Positive Duty Cycle” values - the EMUPro was looking for “Negative Duty Cycle” values. So, when I took another look at the EMU Client and noticed that my Duty Cycle actual value was 92.3 - It immediately clicked. It took a minute but I got it and hopefully you will too now.
I am still getting errors in three of my bins. But like I said, I am now taking a break - even though I really need to keep going. Gotta let these well-done brain cells cycle, lol.
