Been working on some arduino integration into my Z for a little while. I have come with the idea of using an Arduino micro controller to give me a level of calibration to the gauges and give the ability to have warning lights that more modern cars have. I also want to broadcast the values on a sort of CANBUS to interact with other systems.
I purchased a oil and temp gauge on eBay to mess with. I was going to try to repurpose it as a boost and afr gauge, but the bi-metal strips are not near fast enough to keep up with a boost or afr signal.
starting out I have coded warning lights on both the oil and temp gauge. I havent designed a circuit yet for either sensors though. Still just playing around with it for now.
I have ordered a few Arduino Pro Minis to mount on custom printed boards that will run the gauges.
