Finally got version 1.0 of my alternative F53 dash display done. Well, darn near done. One more thing to look into, but overall it's working well.
First pic is a closeup of the display. The one remaining issue is that Tow/Haul should say off. It was working, not sure why it isn't here. Will have to figure it out.
No, the temp was not 480 degrees. It was 48. The extra 0 was a startup artifact that has since been corrected. And the engine is idling and the display is off by one. There should be 2 ticks lit up. That's been fixed as well.
The display is pretty self-explanatory. It reproduces almost everything on the F53's dash except for the Oil Pressure gauge which isn't available via the OBD2 port. I'm really pleased with the Gear display. In this case, the shift lever is in "D" and the tranny is in 1st gear. I really wanted to know exactly what gear it's actually in, regardless of what the lever says. I've also found that the lever pointer rides between some of the numbers on the display - no confusion with the new version!
As seen in the second picture it's nice and bright and easy to see. Plus, I don't have to take my eyes off the road to read it.
Technology is a Teensy 4.0 microcontroller (Arduino clone), breakout board to make it easy to wire everything up, and a 3.2" TFT LCD. Programming is all my own. The research and hacking to find the necessary PIDs (these are all based on "secret" Ford mode 22 PIDS) took about 40 hours.
I'm quite pleased with it, and looking forward to getting out on the road to see how it performs.
Version 2 is in the planning stages. The first step is more investigation/hacking to get more codes, especially those related to the Cruise Control. I want to be able to see when the CC is on, engaged, and what the set point is. I'll also add trip computer functions. And, to see everything I plan to move up to a 5" or 7" display.
