Anyone converted a non TS 4 banger to ignition control using MS2?
I am thinking of using a MSD 6A controlled by MS2 and using the mechanical points with locked advance mechanism as the input.
Anyone have any comments before I commit.

I would be interested to hear from anyone who has done this and what settings etc they used.

Hey, Brett:

I'm looking at doing the same thing (although you'll probably get to it a lot qucker than me). I've used the MSD6A with points and with breakerless. Although the points should be just a switch and really not make much difference, I found that the breakerless set up seemed to work better; the motor just seemed overall a but more crisp. Imagination? Maybe. I used a MarelliPlex breakerless set up. It uses the GM style amplifer which made it plug compatable with MSD. It's really a sweet set-up and, with breakerless, the whole thing is **** near bulletproof. Pertronix makes adapters for various Bosch dizzys and, now I think, for Marelli.

I am a VEMS guy so I do not know to much abut the MS trigger but if it is at al programable I woud trigger off the crank. there are a few kits out there.(even wes has one). I would use a spica pully and grind off one of the teeth. That is what I am doing now but I use the spica wheel side as I am controling the spica. and have the spica mounted. I use a ford type wasted coil. I got a acell very cheap but the ford plug cost almost as much as the coil. I think I will use the GM type from now on. as the connectors seem easy to get. also the ford takes funky sparkplug wires.
I tossed the dizzy. The dizzy bounces all over the place and triggering off the crank is the #1 thing to improve the feel of the car.
I use a grear hall to pick up the spica teeth. I started out with one I got at digikey(round threaded). then made my own, a block that made mounting easy.

if you want to use a single coil you can still use the dizzy to point to the right spark plug. but I would never trigger off it. trigger off the crank.
some of the spiders has some sort of trigger on the fly wheel. if you have that that might also work.

Sly, could you describe in a little more detail how you set up your ignition?
Using the Spica pully and grinding a tooth off sounds like it would be pretty easy signal device, easy to access, etc. I did a search and could find any references to setting up crank fired ignitions.

Maybe not. I believe that the multispark function does not work when you switch the MSD with points.
However with megasquirt the points only act as an input to the ECU and it is the ECU that sends a pulse output to the MSD so maybe multispark will work.

Nice job there sly. Problem I have is that spica was never supplied on alfas over here in Oz.
What do you reckon is the main advantage of wasted spark? Does it actually give a better spark over a CDI system or is it just that it can be more accurately controlled.

Thanx for the replies so far fellas.

there is none. the MSD will be better. but having timming off the crank it the biggy.
see of you can get spica pully and cover from somewhere like APE.

some one here on the BB took a spider pully and had the notches cut into the outside. you could also just drill 4 holes and mount magnets.
there are amy may wasy to do this. I would say even if just need to buy a kit do it.

Thanks, Sly. The photos helped. But if you're using the M/Squirt, especially with a European block, wouldn't it make sense to use engine pully as the reference? That way you'd have easier access to the trigger in case of failure. For the first time I don't regret have 2L blocks with Spica castings! They make a great place to mount the trigger. :)

Brett. From your post I couldn't tell whether you'd used an MSD or not. For the record I think they're the best thing since sliced bread. The multi-firing cd design will solve a multitude of sins and with open chambered heads (got this from a Vizzard book) you'll see some additional hp to boot.

A story. My friend's shop had a Maserati Bora come with with serious plug fouling problems. In did not like stop and go traffic. Two MSD6A's later and it was a totally different car. However, during the install my friend made the mistake of rotating the dizzy while holding on to the coil wire. The MSD fired and almost welded his wedding ring to the finder. He said his arm was numb all afternoon.

I'm still on points and coil at the moment and just using MS for fuel.

Looks to me like the MSD with either a toothed wheel or MarelliPlex would be the go.

Ouch :eek:

yes use the pully. I used the spica side as I wanted to see how well I could trigger off it as I am thinking if I put the trigger inside the spica. I wanted to see if the spica bounced and it did not. But for just triggering it, point the hall the other way and use the teeth on the crank pully(remove one tooth). if not in the US look for a motronic I think thay had the trigger wheel on them from the get go. you could get the whole set up. I think they were common in the 75 as well as others after they stoped shipping to the USA.
