So there's no way to increase the total input/output count? say, have 4 spark out, 4 inj out, 18 aux out, bunch of inputs, etc.? Could I do it if I soldered in some more components or something?

Aux outputs and inputs can be had by using the general purpose IO board, but not for spark or injector outputs.

There's also a router board that lets you do sequential fuel/spark control.

Both of the boards are still in beta testing, and both talk to the MS unit via the CAN bus.

Being a programmer myself, I've been working on various stuff of my own. My overall project is a modular ECU, but I've been testing with smaller scale projects. Right now on my desk I have a little computer designed to read two MAP sensors and control four actuator outputs designed to control a sequential turbo setup & electronic wastegate.

I might be in a position to offer aftermarket programmable sequential control soon, but a full ECU is a long way off.

Please keep us posted on this. I don't mind having to write code, but writing machine code is a new territory for me so I may not be in a good position to help in any sorts, but knowing that it is possible to control aux inputs/outputs is good knowledge, as is the ability to do sequential fuel/spark is a big plus to me and may cause me to sway my previous decisions on ecu.
