Is the eec mailing list still active? I was on it for a while and some of the adaptations being made were far more complex than adapting to a slant. Would be worth searching for those guys as there were several who could tell you about just about any nuance of the eec ECU's.

I would be careful with welding on the cast dizzy body. That can produce unexpected warpage due to internal stress' left over from the casting process. I have a GTAW and this is a project where I wouldn't use it. I'd do a proper prep job of the body (clean & give it some 'tooth'), then use Devcon Aluminum Putty to build up where needed. I have used it to repair and modify small AL engine castings with great success. It is fully machinable once cured and while it cuts differently than AL you can use the same speeds, feeds, & depths of cut as you would with AL.

Thanks for posting this! I learned a few things I didn't know. I think I am running the wrong TFI module on my van.

I don't see ignition advance described at all in the article. What I see if that the dwell control moved from the gray TFI module to the computer on later installations with the black TFI module. Both modules will run at base timing in the absence of the SPOUT signal from the computer.

That is my understanding as well Josh. The TFI module functions the same as an HEI module- spark trigger and dwell control only, no timing control. Timing advance is controlled by the mechanical and vacuum advance systems on the distributor OR by the computer on EFI applications.

Can't say for certain that this one (NAPA Echlin VSS-232, Standard SC-82) is a Hall effect item, but I would be shocked to learn it uses some other technology. HOWEVER it looks as though it's no longer available from Echlin or Standard and probably not from anyone else, in the aftermarket either. Apparently it is still available from GM at a nice price.

If that's a no-go for some reason, look at Echlin VSS-315, which is a Ford item along similar lines, Ford p/n E8BZ 9E731 A).

Alternatively, looks as if Cyberdyne sells a GPS-based speed sensor that puts out pulses which may be compatible with your setup.

Too many people who were born on third base actually believe they've hit a triple.

Cyberdyne makes good stuff, but sometimes it's not available...I tryed to order one of their digital speedos a few years back and it was back ordered for 60 days from summit before they had to drop it due to cyberdyne no longer making the product. Jeg's couldn't get it either.
For a while they made a very nice 'all in one' digital dash cluster that fit nicely in a mid-60's dart dashboard...but after 2 years they discontinued it as well...

Make sure to find an alternate in case you aren't able to get the Cyberdyne item.

Thanks for straightening me out On the dwell issue, Josh.

ntsqd,
Devcon looks like its good to have around. Here is a funny product review from Amazon

I dunno what they did wrong, but the Devcon epoxy putties are a good product to have around. I first learned of it when researching "glass bedding" rifle actions.

That's an accurate description of TFI.- In my neck of the country mechanical advance TFI cars or trucks were pretty rare (a few carburated Escorts & F-trucks in the mid-80's)- most all were some form of EFI so the ECM controlled timing exclusively thru the SPOUT circuit.

The distributor mounted (gray) TFI were terrible- modules failed more often than Chrysler MAP sensors- & that's saying alot. I did fewer of the later black units- but the remote mounted module versions were fairly robust.
Similarly, the older TFI had black Hall effect sensors that went bad often- the newer brown sensors lasted much longer ( but still failed- usually intermittantly)

Something to keep in mind, I've run across a few variations of TFI that were similar to some of the Duraspark ignitions- the module would ground the coil primary until it was "signaled" to switch off. So it was possible to cook the coil by leaving the ignition on with the engine off- like a points system.
