It worked out really well!

Drew up a mount for the 858 coils, then had it laser cut.

Then bent it and did some final fitment.

Then installed everything. SUPER excited about how it turned out.

One more.

That's slick as shit, do you use software for sheet metal fab or just wing it?

I did a couple practice bends, to see what the take up would be, then made a flat pattern in AutoCaad. Then got lucky.

Super short MagnaCore.

Well poo, It didn't start. ms3x, I don't see any tach movement or fuel injector signal.

If I screwed up the wiring on the crank sensor, would that prevent me from getting injector signal?

Yes. You need both cam crank sensors and they need to sync. Take a composite log and post it.

made a composite log, although I have no idea what I am looking at. How do you guys learn to use this thing? Where do I find instructions for this thing. the website explains how easy it is and what it can do, but I just dont get it. I have three unlabelled lines..Again, I am a computer illiterate fuckstick. Why do I look at other peoples logs and see much much more than an unlabeled squiggly line?

I re checked my wiring and don't see anything wrong. yet..

Green is cam. 2 then 1. 2 then 1.

Blue should be a crank signal. There should be 4 crank teeth for every cam. It should look like this:

You are missing the crank signal.

ok cool. investigating now. How did you learn to use this?do you have a copy of the manual? The EFI site lists it, but just keeps rerouting me to the home page.

Just read other peoples threads until I kinda figured it out a bit.

There are forums for the megasquirt, actually two IIRC. Lots of people who have problems making the thing work post about their problems there for help. I read a lot there trying to find answers for my own problems with my MS2 years back, and learned a lot just reading the post from others who had various problems. After a while you see common issues and common solutions.

OK, I am going to go through the wiring again tomorrow. Thanks guys.

Grab a multimeter and check continuity from the connector that plugs into the crank sensor to the connector that plugs into the ECU. Also check each pin for continuity to ground in case one of them is shorted to ground. That's where I would start.

Wiring checks out. Ground is good, signal line is continuous as is the power. Neither ground out from either end. No crank signal.

In a desperate attempt I have changed a few setting from my last ms2 settings when it did run. Not sure if I need to be on wasted cop..I did not wire for sequential spark, but on ms2 the car ran on just wasted spark (not wasted cop) although I did have the ls coils . Not sure about the edge / going hi or low stuff either.

I can't open that msq, what firmware and ecu are you running?

Ms3x, latest ware I think. I mean I just connected it and it is set to update.

looks like 1.3.4
Its crazy, of this entire build, this little black box was by far, the most intimidating part. I was reluctant to ditch the ms2 because I had such a rough time with it as well.

the fact that you cant open it makes me think that It is a firmware issue. Don't I just plug it in and say detect?

EDIT: maybe its this.... MS3 format 0435.16

I googled ms3 latest firmware and it looks like 1.4.0 is the latest release firmware. First step should be to upgrade that just in case your issue is firmware related. I'm on the one right before this (1.3.4 I think...) so I need to upgrade too.
