I have one. It is a board based off of the V2.2 board with addition circuitry put into the board layout.

It is actually the only board design that I know of that lets me flash MSQ's without having to unplug the coils.

I didn't design the board, so I dunno why this is possible.

So the other outputs aren't "high speed" enough? Otherwise even something like the LED outs could be used. :-) A friend of mine (who knows a bit more about MS than I) said there's 4ns pulsing on those PWM lines, but I can't see it being better than 40 - am I missing something here? Anyway, its well within what you'd need anyway - and I was just suprised to see a chip that can talk to the outside world at the same rate it runs at (I'm too used to PC's with a "front side bus) a huge step slower (FSB of a couple hundred MHz to the CPU's core of a Ghz or three.

If it's based on V2.xx, does that leave V3.xx people orphaned?

I got that much... but what benefit does sequential injection have? Smoother engine? More power? Better gas mileage? Easier to tune?

Actually, the Sequencer is its own surface mount board that's more closely related to the Microsquirt than anything else. It's possible that there may be an add-on version of it for existing Megasquirts, but there's no promises there.

Sorry, we don't. It's still in early testing stages and sometimes you never know what turns up there.

Read up much? http://www.megamanual.com/MS%20FAQ.htm#sequential

Sequential injection improves low rev mpg, you can run leaner at idle and it smooths the idle out too.

power is negligable to zero in terms of gains, at WOT the injectors spend more time on than off so sequential batch or bank fire it's all pretty much of a muchness.

Again, in reality this is only a gain for smoother idle, but it should allow you to run much bigger injectors, so you don't necessarily be running them for half your cycle (though it's a bit of a waste not to I suppose). Also, if you can control that many injectors at once, you could do a very competent staged injection, again, something that will clean up idle, etc, without making much more power. But if you were in a gas mileage competition or some other esoteric thing there's an advantage.

Also it likely helps on many-cylinder engines, in the same way.

I am after over all quality of the cars' driveablility. Who wouldnt want factory like idle, tip in and transition? The difference in horsepower numbers may be negligible but overall quality of the setup would surely improve. Of course, for somebody who drives at WOT all the time, it wouldn't make much of a difference, would it?

It's what separates man from savage beast, and miatas from dsms. :-) I love that my car seems stock, except it's a whole lot faster.

Low ohm injectors and sequential injection are two big improvements, as are staged injectors. Then again, so are stock cams.

Someday, I'll get biggie cams, you know, when I get biggie pistons and blocks and such.
