Plan on using an Arduino with a MPC SPI board to control the CAN bus? I was looking into this a while back, and have the parts, but abandoned the project as my coding skills really suck. I just opted to do the swap and it was a lot easier than I thought.
With the dials, I don't think there are 25 distinct speeds, think there maybe 6 with 4 clicks between each as I never really hear or feel a difference in speed. Could be wrong though... |
Haha. No worries. That is exactly what I am doing. I can already control the AC over CAN bus via a Windows app I wrote. I got a dial control module and non-navi AC amp from ebay and am reverse engineering the protocol to write the interface. Then I should be able to control the AC from the dial control module.
My guess is you also have 7 fan speeds. The first click after AUTO is speed 1 and the speed increments every 4 clicks making speed 7 the very last click. That will make mapping fan speeds to the navi based AC amp simple.
Now, if I could only understand what those two intermediate positions do!

Oh, wow... that's interesting... so the last position doesn't increase to 100%? Hmmm...
