Electronic ignition conversion
Hi Guys
Need some help and advice
On my DC I am rebuilding I want to take the electronic ignition off and put it onto the new SC as I am going to EFI the DC during the rebuild
What do I need to do change over from the points and concencer? IF I take the whole distrubuter out how do i wire it up?
Is there a write up about this allready on the fourm?
here is a pic of the distrubuter i want to use

so you must remove the old coil

Re: Electronic ignition conversion
Have look at my EFi thread, there is a pic of the dizzy. Everthing stripped out and replaced with an optic and notched disc. You can use that setup with the standard igntion coil and a TP100 module.

Re: Electronic ignition conversion
if I don’t have the EFI installed why do I need the TP100 module?
what does it do exactly?
I do have one there that was used for the old gotec system that was fitted

Re: Electronic ignition conversion
As I understand it the TP100 is the interface/driver between the elctronic pickup and the ignition coil. Where you had points (really a switch) to fire the coil you now have the elctronic type pickup and the TP100 if you are using a hall effect sensor on the dizzy. It reads the input from the sensor and use that to fire the coil, in some ways it is much like a relay.
In the thread you listed above I think the oke is referring to the ign coil and module that must be removed. He doesn't say what to replace it with though but mentions that you must connect the new dizzy to the coil, so I'm not 100% sure what he means, unless the new dizzy can fire the coil directly without a module(or ballast) in between.
Look at your ign coil to see what module is bolted onto it (think it is a TP80). That will determine what you can do in the dizzy( i.e what input does it need)
See attachment, that might explain it better

Re: Electronic ignition conversion
okay things are starting to make sense to me
just a few things I need to clear up
1. How to you tell the difference on the +ve & -ve going to the hall sensor and also the coil?
2. In the pic is that a condenser wired before the coil? is it still required
3. The TP100 module has 7 inputs number 6 usually goes to the (ecu unit gotech dictaror...) would this now go to the coil +ve or not used?
TP100 wiring
1. Coil –
2. Earth
3. Hall sensor –
4. Ignition
5. Hall sensor +
6. (coil or redundant)
7. rev output (will be redundant rev counter off alt)
eish me is no sparky :alvarin: :alvarin: :alvarin: :alvarin:

Re: Electronic ignition conversion
Do you want to get the dizzy right for EFI?
I had an electronic dizzy on Mufasa before my EFI conversion (I bought it like that). Before the EFI conversion, I did not have a TP100 installed. The replacement of the old dizzy with the electronic dizzy seemed almost like a plug-and-play installation, except that the guys who did it never removed the coil (the coil was disconnected).

Re: Electronic ignition conversion
No I have two hiluxes the DC I am rebuilding and the new S/C
The distributor in the pic is from the D/C that had an crap EFI gotech system installed I have been told that for the correct distributor for the EFI system must have the duel mag pic up, so am going to redo th whole system on the D/C.
So I want to use that distributor on the S/C and change it to electronic ignition

Re: Electronic ignition conversion
Still not sure about the no. 6 output from the TP100, I drew this diagram up

Re: Electronic ignition conversion
Dean, that's a strange looking electronic dissi in the pic. All the OEM elec dissi's for the 4Y that I've worked with have the firing module(tp100) built in. The fact that yours doesn't makes it a real pain to transfer!

Re: Electronic ignition conversion
Ya maybe I should wait a while and see if a come across a standard electric dissy

More like a challenge...
I think that you could safely connect the output from the sensor that would have gone to the ECU trigger input onto pin 6 of the TP100, but it might be best to just check the signal on a working setup to see what voltage levels etc are like.
But given that the +ve and -ve are coming from the TP100 anyway, I don't thing it should be an issue, the only problem could be the signal form ie square wave, sinusoidal etc. Having played with microcontrollers I'm convinced that the triiger input would be square wave as would the output from the ECU to the TP100. Only reason it goes "through" the ECU is so that it could control the trigger angle.

Re: Electronic ignition conversion
This seems to be the one Bennie used for Bulldog, with the Chinese/Korean electronic dizzie but retrofitted with a Toyota coil and external TP100.
