Status update: I just got the digital readout working on my DIY speedometer/tachometer combination. The tachometer has been working for a week and I just got the speedometer part up and running this evening. Using the Parallax Propeller multi-core-micro-controller I have 50% of the project working in the car, on the road with a breadboard version. When I get this complete Yaris owners that have altered their tire/wheel diameters will be able to correct the readout on the extra instrumentation to GPS accuracy with just a laptop.
Two parts still have to be programmed: 1) the 33 lite LED analog tach. 2) the outdoor temperature and humidity sensor for the in dash display.
