Greetings all:

Ah, heck...Here, then:

I've installed a Ford EDIS ignition system on my 73 TR6. This, of course, results in no distributor=no tach.

I've read of people 'cutting down' the stock tach to provide a tach drive.

Anyone have any more info on this?

Failing that, I suppose there is a way to adapt/replace the stock tach with something electrically driven?

Thanks--

bob I sent you a PM but tell us more about the ford EDIS, where did you get the components? what year, did you have to modify anything besides the distributor?

Better living with a hack saw.
Had a feeling we where going there.

Eeeek. :eeek:

Just....just...just cut it off and weld a cap?

While (I must admit) I was looking for a 'cost effective' (tm) solution, I thought that there might be a bit more to it...

Any reports on the success of that surgery? It looks like the updates stopped after the cut was made.... :shocked:

It's mainly hardware from a 90's era ford V6. Wiki EDIS

I had to make (have made=water jet cut-->I probably have the file and vendor info around somewhere...) a trigger wheel that I mounted to the harmonic balancer, as well as a <simple> bracket to hold the sensor. I can send pix if you're interested.

The Ford parts were scrapyard stuff--though I sourced them all at once from e-bay ( Ebay EDIS6, for instance). The module and a pickup--as well as a trigger wheel that I had no use for :frown: and tail ends of the harness--the right plugs.

It's a whole lot like this <--->. I'm controlling mine with megasquirt--as I'm injected now, too.

Bob, I'm sure you could email Andre and ask him, he is a very friendly chap...
 
Ta-da!

I have to ask, have you noticed very much improvement ( engine smoother or stronger)since the conversion. I like the concept but is it worth the effort.

I've been running Rick Patton's Throttle Body Injection for almost 5 years now and it totally transforms the car in terms of drivability. The big difference between the Ford EDIS system and Rick's TBI system is that the car is now fuel injected and the ECM controls everything..... not just the timing.

These conversions..... be it EDIS or TBI aren't for everyone but the car sure drives better.

What's funny is that Rick's own TR6 is direct injected & supercharged.... of his own design and also has the cut down distributor...........which I've never noticed before!

Don't mean to hijack this thread......from Rick's site

<span style="font-style: italic">"This supercharger installation is on a multiport electronic fuel injection system."</span>

It's not TBI, which won't work with his SC...... maybe direct injected was the wrong term to use....

Now back to our regularly scheduled program.........

Hi Bob,

I am curious as the the reason you needed to have a custom trigger wheel made? I am eventually going to do a simmilar conversion but with full EFI and electronic ignition. (probably megasquirt), and I know that some folks have used the Ford V6 trigger wheel from 80's or 90 econoline vans etc.

Thanks

Todd

Robert I stand corrected.
I just looked at the end of the intake and saw the butterfly and figured TBI. As soon as I read your post I understand what he did with out looking at it
 
Hi Todd:

I wanted a trigger wheel that fit on the <span style="text-decoration: underline">back</span> side of the harmonic balancer--out of the way--like stock fitments do. I couldn't--at the time--find anything that would work the way I wanted, so I drew a few things up, had my friend (with a laser cutter :smile: )cut me out one or two basswood blanks to check fit, and then sent the file off to a waterjet company to have executed in steel.

It still took a little fine tuning around to fit. :frown:

That said, I've got no idea if the trigger wheel for an Econoline would've fit as nicely.

But I'm happy with the way it looks. With the exception that the timing indicator pointer had to be cut--the trigger wheel spins through that space.

FWIW, I've fitted Megasquirt to control the ignition--along with adapters from Patton Machine for the fuel injectors :wink:
 
Bob: I'm late to this topic, but a few of our club members are running the EDIS in their cars with great results. Our club is DCTRA and we have lots of information on the site. I can't take credit for any of the information but it's free just take a look. Once you have the homepage look in the left top corner for Categories, then Articles and Documents. Then scroll down past all the Triumph Bulletins to TR6 Electronic Distributor-less Ignition. Members have had the systems in their cars for years so the information may help.
 
I've been ill for several days and missed this thread so I can only offer are questions, not constructive answers.

1) Apart from cosmetics, why bother to modify/cut down the distributor to retain the tachometer drive? You could remove the points and plug wires and leave the "dummy" distributor there to drive the tach and confuse people looking under the bonnet.

2) The GT6 tach is calibrated for 3.55:1 rotations. I assume the TR6 would have to be the same. The spitfire also uses the 3.55:1 ratio which means they should all have the same distributor drive gears. So... if you have to cut up a distributor for your conversion, why not get a used Spitfire distributor which is bound to be more common and less expensive. That way you could save the TR6 distributor in the event you (or a future owner) want to "change back" later.
