Megasquirt V3 ?, Just a few questions for the MS crowd Options

[alpha434]

Does it support direct port injection yet?

That's the first one on my list.

There's some information on the megasquirt.info site on the Router board. It uses the very processor you mentioned, jsteele, the MC9S12DT128. It gets injector and ignition timing hints from the main processor (which has to be MS2) via CAN, and handles the crank and cam signals entirely on its own, providing 8 injector and 8 ignition signals, so you can do full sequential on a V8 with COP.

The one downside to this is there's no way to have per-cylinder control of injection or ignition, so no fancy stuff like ION-sensing ignition. All cylinders will get the same injection and ignition timing. Given suitable injectors and the rest of the mechanical stuff to back it up, however, you could do direct injection on a V8 with this. Think of it basically as a user-programmable EDIS controller that can also do injector control.

The boards can be slaved (this is a feature of CAN), so you could have two of them to handle up to a V16, if you just happened to have one of those lying around. And if you're planning on injecting some old aircraft radial, you can put in a third to get 24-cylinder control. MS at the Reno Air Races...

I suspect the really advanced stuff like ION-sensing they're either thinking of hacking onto the router board at a later time, or waiting until they get to UltraMS.
