MS-II Sequencer
Who is getting ready to switch to MS-II sequencer? Ive started my homework on it and I'm discovering some neat features about it. I think I am going to order it as soon as it comes out.

There are so few of us that are MS-II even that I can't imagine many people jumping on board, but if you do, please report back as we need people to pioneer (cough...cough....guinea pig
) stuff like that. Hell, there was a time when going emanage was a big deal and MS-I wasn't even on the radar.

So this must be what became of the router board. My big attraction for the original router board concept was the ion sensing. That got dropped because there was trouble getting the crank angle measured accurately enough to do any good. Last spring (I think) I remember reading a post by either Bruce or Al that they may have solved that problem and there was some hope we might see ion sensing again. I didn't see any mention in the link that RDSnake posted, though.
For anyone that doesn't know, ion sensing has the potential to do for spark what wide bands have done for fuel. Perfect ignition timing without a dyno.
Other random bits of info: We would also need a capacitive discharge ignition (CDI) system to make use of it. I think, but cold be completely talking out my ***, that GM used a system like this around 2000 for mis-fire detection (no crank angle calculations).
On a completely separate note, I'm a little concerned that more and more MS parts are coming in SMT. I hope us DIY'er aren't forgotten.

Oh, your ion spark talk stuff sound really interesting. I'm gonna have to do some research on that. Let me know if you got any good links on it.

This is a direct quote from the megamanual website:
"The price for the MS-II Sequencer has not been set yet. Initial estimates are that it will be a 35 - 40% increase over the cost of MicroSquirt, since there are roughly 35% more components, and the added harness assembly, Ampseal connectors, assembly cost, and enclosure, plus the extra cost for the aluminum and panel cutout for the second connector. Since MicroSquirt retails for about $400, the estimated price is likely between $520 and $580. This could change somewhat, but is a reasonable ball-park figure. When pricing is finalized, it will be posted here."
How much is a MSPNP and what kind of MS would you get if you bought one?

Yeah - I was pretty excited about it, but I'm not sure about the mechanism they are going to use - it really seemed a lot more aimed at V-8s. I was a little worried about the accuracy of the whole thing. Like, do they really need to scale a factor of ten? And, what keeps MS limited to two channels, anyway? That doesn't make sense to me.
SMT isn't so bad, and you can still mod it. Sure, it's a little more of a pain, but not a lot more. Getting a board built then swaping a few things out is still possible. I almost did it on this one.
I, too, and really curious about this ion sensing. A lot of stuff gets done for emissions than have no benefit to power output... And generally mask problems (think MSD folks).
I guess you could technically build your own sequencer external box, but I wouldn't. :-)
