remote mount TFI

[bax]

I have a direct mount TFI ignition module. it is mounted on my distributor. I am having troubles with the heat ruining the module. I want to change my set up to a remote mount. How do I do this? can I just take the module off the dist and mount it to say the firewall? Then just run 3 new wires from the spade connectors on the module back to the distributor? I have seen a remote mount that the module sits into but I dont know how it is wired. Where are the 3 wires back to the dist?

learn me something please.

here is one way

i used a oem remote mount distributor and a few wiring diagrams to wire it up. I used the gray TFI module and distributor from the same truck.

and

i used those two diagrams and wired the remote mount TFI and distributor into my 89 5.0 mustang harness. works great.

Does the module have to be mounted in that aluminum housing? Like in picture 2. Where do I get that? My module has 3 elect connections on the side of it.

that is a heat sink so i would use it. get it at the pull a part.

The remote TFIs are different modules. It requires a few more wires to the distributor.

Here is a different method using the original distributor and module.

Black and gray are different? If I am using a gray direct mount module and should be using a black one, what will that do?

 

[Viperwolf1]

Gray is push-start and black is computer controlled dwell (CCD). The difference being how the ignition dwell (coil saturation) is determined. The long answer is on page 2 of this pdf: http://capitolautomotive.com/pdf/cccnewsletter.pdf
The short answer is it may work, but not real well.

If you have your wiring diagram you can determine which module you should be using. If the wire going to pin #4 on the EEC-IV computer comes directly from pin #4 of the TFI module, it is a CCD system. If not, it is a Push Start system.

if you are using a 5.0 computer you need the gray one

Here's my diagram for how I wired my RTFI (gray) setup into my 'Stang harness.

nice link, thanks ;D

So, I have an A9P/L computer, I have a dizzy with a grey TFI on the side, those should work OK together even though the TFI articles says in early 90 they went to CCD?

Can I find a "grey" remote mount TFI dizzy and use that, what year/model would those be from?

Color me confused.

this may be why some are having driveability issues...

 

[Bronco_69]

the 87-93 mustang had gray distributor mounted tfi's. the 94-95 had remote mounted gray tfi's. not sure of the years on the trucks.

you can rewire your set up to be a remote set up. read the 1st link to the ranger station

 

[73azbronco]

Bronco69, i like what you did, thats a stock 94-95 dizzy on yours?

 

[Bronco_69]

mine is a 351w. it is the stock distributor from a 94 bronco and the tfi also came from the bronco. i decided to try this because my 351w was a roller motor and i did not want to buy a msd 351w distributor with the steel gear. i am a cheap bastard

 

[bax]

;D You cheap Bastard you!
I read thru all this stuff and it looks like the only way I can do this is 1: first figure out what module I should have. it looks like I will have to trace down the wiring to see how it is wired to see what one I should use. or ask Holley what one ( Commander 950 system)
2: It looks like the mod where you move the moduel onto a heat sink and then add the 3 wires back to the dist. kinda ugly but if it works I am good with it.
3: if I can't get this injection system to work better for me I will pull it off and go to a carb.

 

[Bronco_69]

you could swap for a ford efi system and be good to go

i am way cheap

On my 400 motor? I guess I could work on that.

 

[Bronco_69]

oh, that could be an issue.

in reality all it would take would be a custom distributor. mate the top half of a ford EFI distributor to the stock lower.

or your holley distributor may even work. if it has a TFI i should work.

i bet the rest could be bought off the shelf. they make elbows for putting throttle bodies on carb intakes. they make intakes with injector bungs, etc.

i doubt it would be cheap though


edit

I just looked at your gallery, very nice bronco!!!!!!!!!!!!!!!!!!!!!!

 

[Bronco_69]

after looking at your pics it almost looks like you could plug a ford efi harness into that set up. you have the TFI, 8 injectors, etc.

you would need a ford TPS (it may have one on it), air intake temp sensor, engine coolant sensor, 2 O2 sensors, and a mass air sensor calibrated for your injectors.

connect the mass air meter into a cold air intake tube ment for a carb. place the AIT sensor in the same tube. the coolant sensor is easy.

a speed density set up would allow you to run the carb style breather but i suspect that SD would have a hard tiem with your engine.

i could have a ford efi harness on that truck in a couple hours
