I collected a few more parts for the speeduino setup like a skidoo trigger wheel and magnetic pickup.

I also printed a small bezel to cover the display

and configured TunerStudio lite to connect to it

the next thing is to collect more sensors. I want to use a Bosch O2 sensor I have left over but I couldn’t believe how much they wanted for a sensor bung. Its just a threaded nut but they want $20. So I Bought some 18MM Spark Plug Non-Foulers for $8 and trimmed them down to size…

Of course its been raining for the last few days so the cart will have to wait….

If it works well enough I may try it on this older Bolens Hydro Tractor I have out back….
