I've used the Megasquirt EMS computer for years in my Jeep and have a good understanding of it's capabilities. With my Mazda Rotary 20b engine I'll be running 3 rotors, 6 fuel injectors, 6 ignition circuits, fuel pump, water pump, and 12 monitoring channels. I will be able to log and tune all from a raspberry Pi computer located in the dash. I'm currently doing all of this in my Jeep, and have decided to design a custom dashboard with TunerStudio software. Here's a pic of what I have so far.
