The LCD multi gauge system is finally complete. The page documenting how to make it is done: Multi-gauge LCD Display. It’s a very long page that chronicles the development process. Scroll to the bottom to see the source code.
It’s great driving with more knowledge about the state of the engine. Oil temp takes a lot longer than water temp to rise for one. The intercooler is very effective as the probe before the throttle reports about ambient 90% of the time. I think I would like to add a cheap map sensor to graph boost on the display at some stage in the future.
My old one was out of date, so today I purchased a new helmet ready for a return to drag racing in early January. I’ll look up what drift is available too since I have the oil cooler and winged sump in place. Fun times ahead.
