My name is Ethan. I just purchased a Disco board that should arrive soon, so I can have a play with rusefi.
I have a brief electronics engineering background (EE degree), so I know embedded software and digital electronics.
I spend most of my weekends tinkering on older cars (80s and earlier). I have a some experience with EFI systems, but I have always wanted to convert a carb/dizzy engine to EFI and Electronic spark.
I have looked a lot at the Megasquirt range of stuff, but its either far too complex/expensive for what I have in mind, like the MS3pro modules. Or its been abandoned technically, like the MS2 range.
Ideally what I am after is something that has a feature set similar to the MS2 hardware, but without the downsides.
The issues I have with MS2 is that there are two options the Microsquirt range, which end up being expensive for very limited functionality (2 inj and 2 spark channels, only a few i/o). Or the V3 mainboard/daughter board kits which requires extensive hardware modifications to be useful and means you don't end up using the majority of what you pay for.
My Ideal DIY ecu would have the functionality of the MS2Extra firmware, with hardware that is actually designed to match it.
This would be my ECU wishlist:
- 4 Inj Channel outputs (1 channel can drive a low impedance injector or 2 high impedance)
- 4 Spark Channel outputs (logic level, so would require an igniter module for standard coils)
- 2 Engine Angle sensor inputs (VR/Hall/etc configurable)
- The 6 standard ADC inputs (IAT, CLT, MAF/MAP, TPS, WBO2, BAT)
- 4 Digital/PWM Outputs (used to control relays / boost solenoids / idle solenoids etc)
Nice But not critical: - 2-4 Digital inputs (simple inputs, no knock sensing or speed sensing)
- 2-4 Configurable ADC Channels
