Can all of our computer controlled distrubutors be upgraded with aftermarket controller?

Can all of our computer controlled distrubutors be upgraded with aftermarket controller?
Has anyone heard of this being done?
As I researched it, our computer controlled carbs control the ignition advance through the EEC-IV system. Our distrubutors send a signal to the EEC-IV system, that EEC-IV system reads various other sensors, and sends a signal back to our distributor.
Has anyone tried to actually work the existing distributor factory installed on our trucks?

I have not found anything for the EEC4 TFI ignition system so far and I been looking for some time too.
There is a aftermarket spark controller that is used for the Ford EDIS system.
Here's that link for the EDIS.... http://www.autosportlabs.net/Megajolt_Lite_Jr.
It may be possable to modify the software to operate a TFI system or design something up along these lines.

What Patrick and I are looking for is to use the TFI ignition system and carb without a ECU controlling the timing and carb(replace feedback carb to non feedback carb). Without a ECU the TFI is locked at base timing. I ran my 84 F250 that way till I found a good ECU at a reasonable price. Also the feedback carb gave me fits so I finaly went to EFI years ago. Now I am going back to the old Dura Spark 2 and Oppy DP intake and carb.
I did find this tonight.....

Yes exactly. I found those links also. I plan to make one and report back results. I even did basic math timing calculations for how fast the signal would have to be..
My thoughts were a purely distributor based system that can produce it's own "SPOUT" after around 1500 rpms.. The module could be really cheap if mass produced, and all it would really need is +keyed ignition 12v , PIP (out to ecu), and intercept "SPOUT" . I am not even sure that the EECIV could pickup on such a disabled "SPOUT"

I'll save my criticism of MSD because it is well known.
The GM module controls dwell so you don't need a ballast resistor in the coil feed and can use your old Ecoil.
I don't know of ANY aftermarket performance EEC-IV computers..
Who in their right mind would use a feedback carb and TFI distributor in that application?

I'm not aware of your criticism/issues with MSD (I've been reading all the posts here for a while now and don't recall seeing anything).
I'm interested in what issues you've had because I run the MSD 6AL with an MSD Pro-Billet Street distributor and Start/Retard box. If there are known issues with these parts I'd like to know before I have an issue. So far everything is working fine.
Could you link me to one of your posts of just send me a quick PM if your issues are related to the parts I am using. Thanks

The Tfi-IV distributor is basicly just a hall effect sensor, the ECM and the ignition module are the brains of the operation. The older TFI modules handle dwell in the module.
This is the only thing I have ever run across that does what you are thinking: http://www.gofastforless.com/ignition/digital.htm
That is complely build and program it yourself though.
You may be able to do it with Megaspark as well(project was circa 02-03, and uses a megasquirt controller) but due to Ford using one window larger than the rest to tell the ECU cylinder position you will always end up with different timing on #1 than the rest.
You will also have to design and program your own timing curve and will not have a provision for vacuum advance.
This is why a Duraspark or HEI conversion is the common thing to do, mechanical and vacuum advance are tuneable and much more user friendly.
As for msd stuff I have run my 460 on a Digital 6 plus with a DS2 dizzy since 07 and have never had an issue.
I have seen a few of my friends have issues with 6a boxes though.
I run the DS2 dizzy as while it is a bit harder to recurve than a MSD unit, I prefer the bigger cap diameter and MSD uses a duraspark pickup and reluctor ring anyhow.

Check out this MegaSquirt link.

Another useful link.

And one more. I believe MegaSpark was the original MegaSquirt project. Looks kind of dated today.

Ya know you can just use one of there Cap-A-Dapts on there MSD dizzy, it's basically the stock DSII bottom cap adapter.
