excellant link, I was looking at one similar a few months ago but it was hard to get it all, that one was straight forward.
I need to buy the mJ lite controller and then get the rest from you or the pulley and the edis parts from a 4 cyl fomoco, correct. I dont really think it needs to be balanced. I will wait and see how much you develop the prototype
Right. I should probably put together a complete parts list with sources and stuff. I'm starting to think now that I'll have to try using the larger type trigger wheel instead of the smaller one like I used. Because of how wide the sensors are the wheel has to be spaced off the surface of the pulley a little bit, but if it's out too far it will interfere with the PS belt. With the larger diameter wheel the teeth will be out (radially) just past the alt. belt groove, so the wheel can be mounted flush instead of spaced out.
The bad part is that the larger rings are more work to get off the car to begin with. The good part is that they are bolted to their native pulleys instead of press fit, so they won't have to be cut off the Ford pulley like the smaller ones. Another trip to the JY. Yay!
I talked to my machinist buddy yesterday; and as it turns out the machine he normally uses to do this kind of stuff (modifications on existing parts) has a problem with the X axis (meaning it's basically a manual machine at the moment). So I need to see if I can fix it before we do the pulley stuff on it (see * below). Otherwise we have to work out a way to do it on his machining center. He normally only uses that for more complex or multi-part jobs; the stuff that keeps him in business. So he doesn't like to do easier one off kinda stuff on it.
The other issue is that he's moving to another location in roughly 2 weeks. So there will be a short transition time where he won't be able to do any work. It don't think it will be a problem but just something to work around.
Anyway, we'll figure it out.

* Once in the past this machine had a computer problem (it's PC controlled) that I was able to fix, saving him a call to Bridgeport tech support and the cost of a tech coming out to look at it (big $$). So now he always calls me when it has a problem. It's kinda like those people that find out you know something about computers and always want you to fix theirs when they do something stupid like install one of those "Internet Speed Booster" programs that really just hoses their system with spy ware. I swear I need to get one of those shirts that says "No. I will not fix your computer." I guess he's really not that bad though, and he does help me with machine work. So in the end it's cool.
sounds good
I havent been to a JY in months, I need to go see what is up there.. Honda wise... and
Ranger trucks? tempo, escort, any mazdas? I know some of those are inside the timing cover, some on the outside.
i know of some after market ecu's that can run two differant fuel and ignitionOriginally Posted by roodoo2
maps, just so the mechanics cant thrash it when its in for a service
With the flywheel trigger , i'd imagine that if you could tell the ecu or what ever controller you were using how many teeth there were between tdc for each cylinder it should be able to do it.
I mean if you need to mark each cylinders tdc, there would be away of doing it
sink a magnetic plug into the fly wheel at those points or something along those lines.
would be a challenge, but a worthwhile one i'm sure
I don't see any advantage to triggering from the flywheel. Especially since the EDIS system works so well and is so simple.
As for EDIS parts; they're found in lots of models. Once you know what the parts look like you can just rummage around until you find something. Escorts and Tracers are probably the easiest to find since they sold millions of them. Like Civic's.

Im getting mine from you since you volunteered to assemble some.. but I was at the JY yesterday and hell I didnt realize there were so many different engines in the escorts.. I never did see a gear, some were DIS but no gear unless it was inside the cover. I was on my luch break so I didnt have a lot of time to explorer I got distracted by the antique car lines.
I was reading up on EDIS, there are a lot of car collectors going to this. I see where it is easier to get the trigger wheel from taurus and mustang V6 engines, same teeth and not pressed on.
I ran across an IMP forum, wow.. My dad had a Simca back around 1966, I have never seen another one other than the pictures of his...until today. Interesting stuff, that company was bought by Chrysler and that is where the bodys for Cricket and Omni came from. Yes even IMP fans are going EDIS. Now to write Santa for MJ lite jr...
Just a quick update:
The machine shop is about to move to another building (tomorrow!) so will be down for a few days. The Bridgeport is fixed though so it should be ready to go after the move.
I did start on the prototype using my little lathe though. Have a pulley now with the AC groove cut off and a trigger ring ready for mounting. Now just need to get the holes drilled in the right places and bolt together. Then can try test fitting on the car.

what are some well tried methods of mapping the T curve. I am reading various ideas, some using pdr and some other devices that write to the MJLJ?
carbed carbed carbed
For setting the timing map in the MJL you can use any PC with a serial port. If you don't have a serial port you can use a USB to serial adapter. For actually mapping the curve with a stock distributor, that's something I haven't tried yet. I have a map for my Megasquirt that should be pretty close for most A20s. One of these days I am going to try and reverse engineer the curve from a stock distributor though.

How are things going with those pulleys buddy? I have since gathered all the other components for the EDIS system(some brand new and others jk special)...just waiting on those results for the pulleys.
Happy Holidays btwand that goes for all my 3geez buddies !
do you have a picture of the finished product? i just want to compare it to what i did to my pulley during spring
Not 100% relevant, but my modified trigger wheel from electromotive came a while ago. I need to take the trigger wheel off and hit the pulley with a light coat of paint to keep it from rusting, but then I will take some pictures of it. Looks pretty excellent.
My wheel uses a 60-2 wheel for use in the Electromotive TEC-GT system, but you get the idea...
heres my motor with the trigger wheel welded onto the crank pulley itself. i just wanted to see someone elses for comparison and to see if it can be improved in the event i decide to build another motor up

Clarification :you mean paint the pulley and not the trigger wheel ? , Im not sure even that is a great idea, do not want paint inside the pulley or paint making the surface uneven so the wheel wobbles a bit.
yep painting the pulley. the trigger wheel is zinc coated and will not need paint to stay rust free.
light coat of paint.
the stock coating is all gone from when the machine shop balanced and acid dipped it. it will rust badly (already started to rust) if i don't hit it up with some flat black rustoleum. I agree that lots of paint could affect it adversely, but I will be careful not to go overboard. but yeah the mating surface will probably be masked off. it shouldn't rust too bad if i put some oil or something behind it to keep it from oxidizing etc...
Unfortunately progress has pretty much stalled in the last month. Just too much going on during the holidays.How are things going with those pulleys buddy?

Anyway, I just sent my machinist friend a 3D file of a mounting jig for the pulley and trigger wheel. The jig will make it much easier to run multiple parts with repeatable results. I can do everything with manual machines, but it's slow and each one would be different.
So hang in there guys, we'll get it going.

Hrmm, I am wondering if there is a MSD product that is equal to the MJ jr, that would work for this EDIS set up.. I was looking through the Summit catalog and there must be a couple dozen controllers. I have not researched the specs on them yet. It seems like the rest of the world is using the MJ jr with borrowed EDIS parts though. MSD looks to be more expensive I see.
(have summit gift card, and they have no MJ products listed, errrgh)
^^incoherent babbling I guess
There are several brands in Summit that have simiilar capability as MJ jr, but I guess a proven avenue is the way to go without buying stuff that isn't going to work as well.
I can use the gift card on A/F meter or something.
I looked at MSDs web page and I didn't see anything in their ignition products that would help here. And they are quite expensive. I think the MJ + EDIS combo will be hard to beat price wise.

I've been lookin into this type of dizzyless ign as wel and think have a post in this thread.
after some digging thru the old text books etc have found a way i think will work
i plan on using subie inductive pick ups and using the flywheel ring gear as the trigger
all i need to do is fig a way of taking a tooth of the ring gear as a tdc reference or add an extra tooth butted up against one,as to make a tooth twice as long to give same tdc ref point.
also investigating usin subie coils
as in one per cylinder mounted on the plug itself
all this will need an aftermarket ecu to run it but i think will work and be well worth it.
am "borrowing" pickup and coil from a dead subie motor at work
will try and get some pics as i go so to show you'se all my idea
Just a note, I haven't forgotten about this project. In fact I should have a few pulleys done in the next couple weeks. I've been putting up with a lot of crap from my job and haven't had much free time. But I've finally had it with those bozos, so I gave them my 2 week notice. As of April 1st I will be unemployed and will have plenty of free time for fun projects. At least until I find another job.

I wish you well, and thanks for chiming in.. I have taken on a few other projects on the Accords to keep me occupied meanwhile..

Oh wow, this is old! LOL!
I have made a few of these since then, although it's more difficult now since my source for cheap toothed rings (pick n pull) is gone. Need to find another source.
