Ordered - thanks!!

So, by accident I broke off two of the pins on my MS2 daughterboard - the ones that fit in the socket on the mainboard. Does anyone know where I can get some of those pins? I noticed that they are soldered on in a strip, but they can also be cut to length, so I just need two pins worth. Anyone have ...

Too bad I don't have my logs with me because I could compare yours to mine. What are the specs on your engine? I have an essentially stock 78 2L engine. I'm running fuel and spark with the ms3 and using the v3 board, but I might be able to help compare settings and get things straightened out for yo...

The blade's probably dull and needs sharpening...

Here's a very neat trigger wheel idea:

Right on! I'm working with someone else that is adding the MS to his bus. I'm going to use your wiring diagram for his setup to keep things really clean. If I notice anything out of the ordinary, I will definitely let you know.

Yeah, while I thought my compufire was pretty accurate, it's amazing how rock-steady the timing mark stays!

Also, make sure you leave the mechanical/vacuum advance enabled as it will just help to keep the rotor aligned with the correct post. Uh, is that true? Oh, sorry about that - the vacuum advance makes no difference because it just moves the breaker plate, which obviously isn't being used - Sorry, my...

Interesting to read some different opinions on this subject. Still. I'll think I'll go with a dizzy for spark distribution and the MS/trigger wheel for timing. With a modern distributor I'm using (Mallory or 123 ignition) it should not be such a huge different with an EDIS setup, since the dizzies ...

that's pretty slick. What is the minimum diameter of a wheel? The pulley's OD was about 1/2" or so greater than the ID of the Ford EDIS trigger wheel. I wonder if I could have just mounted the pulley on the indexing wheel and milled out the teeth on the pulley...

It's hard to explain unless you've experienced it yourself. Once EDIS was on, it didn't run like a Volkswagen anymore, it ran like a modern engine. I figured the biggest benefit the EDIS would have would be better adjustability but literally everything about the engine was better. I think a hidden ...

Both set ups have pros / cons, it probably comes down to what a person is most comfortable with and what kinds of spares / tools one like to carry. If it did not offer some substantial advantages (performance / cost / reliability), I doubt Ford would have never put it into their cars. Yeah, I can s...

Why's that? (assuming that the distributor is only distributing spark)

Well, EDIS modules seem to hold up better than caps and rotors from my experience. Some of the other benefits would not apply if you are crank triggering a distributor, though. Yeah, I think from a mechanical standpoint, yes, there is a big advantage. However, to be able to swap back to the stock s...

EDIS has every advantage over a distributor. You eliminate moving parts, get more accurate spark control, infinitely better tunability, more reliability, I picked up some milage. The only advantage I could see is that you don't have moving parts so you might have more reliability. How would you get...

Matt Cramer wrote:Ok, that sounds like a good plan. I was just thinking of the stock TPS, which could have been a problem.

Yeah.. I got one of those in a ziploc in the garage. I wonder if the bosch TPS and that throttle switch use the same connector - wouldn't that be handy!

I'll be installing my VR/trigger just like yours mike, I really like the look of that setup. I'll probably add a connector in my wiring harness so I can unlpug the VR and plug in the coil in case I would need to switch ignition systems on the fly. Just make sure it's shielded! If you don't, you *wi...

If memory serves several of the sand rail guys are using EDIS - that is a pretty harsh environment. EDIS eliminates all moving parts and delivers a strong spark - there is probably a trade off of mechanical distributor failure / rotor / distributor contact wear versus electrical wiring / electronic...

don't know much about L-Jet -- but IIRC the older busses used D-Jet which definetly has a switch type TPS -- which is not compatiable with MS. That is correct, but the throttle body is compatible... well, with the correct TPS sensor :) The nice thing is that bosch looks like a good bolt-on replacem...
