Re: Uh-oh... What did I kill...

The coilpack is still the same Subaru unit that I pulled off of a junkyard car, together with plug wires and connector pigtail. It came off of an early 90's Legacy, I think. The plugs are NGK's with stock (really small) gap.

It looks like people used ~2.5ms dwell on those coils, but I couldn't tell ...

Re: Uh-oh... What did I kill...

I'm getting there! The diagram is kinda conflicting with the label on the back... According to the label on Microsquirt, my ignition drivers have opposing wiring, such that Ign2 is wired to resistor R38 and Ign1 (the one I had trouble with) had R39 left, which is what I hooked it up to (there's a ...

Re: Uh-oh... What did I kill...

SAVE ME SUPERMAN!!!

I have regained ignition on one of the ignitors by inserting new VB921's and re-flowing the whole thing. The second replacement VB921 (the one further from the connector) landed well, and has ground and output showing fine, but there is no input signal going to it (the pin that ...

Re: Uh-oh... What did I kill...

Ok, I got some very steady signal by drastically shortening the sensor wire. Unfortunately, VB921's are actually dead - they were grounding the ignition at all times, causing the whole thing to overheat as soon as I would connect power to the coil.

I pulled them out, and I'm now trying to replace ...

Re: So, I fried my Microsquirt today.

Awright...

Mine looks exactly like this. I have a stash of VB921's, so replacement is not a problem; my question is, what points would be the best to connect to, given the fact that the original locations are pretty much fried?...The center pins are easy since they have a huge trace going to them ...

Re: Uh-oh... What did I kill...

Ignition trigger is a spare Ford EDIS VR sensor that I had, one wire is routed to signal, and the other one is attached to the shielding. It is triggered by a plastic drum with 7 bolts attached so that the heads form a 8-1 trigger wheel. I did leave the dwell as is, since I have no inductance meter ...

Uh-oh... What did I kill...

I just got my Microsquirt project motorcycle back to my house (if I have to push this thing for 3 miles again, I'll put pedals on it). Now, for the past couple of weekends, we've been trying to get it started, and had a hard time getting a tach signal. So today I take the MS home, and it smells like ...

What's next?

I know this is a little premature, as Micro is not even out yet... But, are there any plans to introduce an even SMALLER... Megasquirt? :) What I'm saying is that a single-cylinder versatile controller with simple wheel-based optical ignition would be great. Something that would fit on large model ...

Thanks for the link! This should help me out with wiring. I got the fuel pump yesterday, so hopefully I'll begin tuning this weekend, if I sort my ignition issues by then.
As for yamaha bits... Suzuki throttle bodies are almost double the price, for some reason...
Plus, those weird slide thingies ...

Well, my GS is aircooled :) But I'll try the cold/hot water trick, if it works I'll try to run my oil line through that, or something of that sort.
