I'm not sure who was letting us use their phone for the ms3 portion, but thanks for doing that!

Ken

Nope. Not that I know of.

I don't know where all the beta testers live, but I'm pretty sure none of them are over that way.

One of the 1 or 2 ms2extra users that are going would probably be able to help.

I don't think I'll be able to make it or I'd help.

Ken

Just priced it out, and it'll end up costing me close to $1000 all said and done (plane tickets, car rental, hotel)... I'm afraid that means I probably can't make it, although James and I would be glad to put together some slides for MS3 and go over them remotely.

Ken

Heh, if I'd have known about this a couple weeks ago I might've been able to go. I'd have liked to do the MS3 update in any case.

Right now money's tight (buying a house) but I may try to make it anyway if I can find a decently priced plane ticket and hotel room. Anyone want to share?

ahh, so I guess they're doing fixed timer intervals so they "know" they won't have a timer event running into a spark event...

My code at its worst should have around 10-20 usec accuracy... it's only limited to how long an OC timer has to wait when other interrupts run...

So far in my ...

I tried drawing the schematic in ASCII, but these boards don't let you put multiple spaces in or I can't figure out how to do it anyway. With the Zener in there, +5V is on the IGT pin and is grounded when I switch JP1 to ground, where the VB921 will go. +12v (no Zener) didn't work too well for ...

I hope you're not just leaving it ungrounded... in this configuration you'll want to have it grounded all the time until you're ready to dwell the coil, then you'll want to unground it briefly and then ground it again.

Essentially what you're doing when you ground junction point 1 is pulling the ...

like I said before, you're going to need a pullup resistor, which is fine, but if these things are anything like my rx7 ignitors (they probably are, both are denso), then the stock ECU is providing a +5v square wave....

So instead of doing a pullup to +12v, you can do a pullup to +5v.

The ignitor ...

Stupid question for the assembly coders. I code in C on embedded linux systems here at work. Debugging is pretty easy with a BDM tool or just using "printk()'s" but I don't understand how you guys debug the MS code. You can't really output any debug messages and there's no BDM tool or anything like ...

If you're going to be building a lot of megasquirts (for friends for example), you may want to consider a more expensive weller iron or something similar.... Those radioshack iron tips die very quickly.
