Electronic Distributor Adapter

[90TurboVan]

Pretty sure its just the world engine that has COP. I have the code done for NGC to TD. Uses cam and crank sensor to simulate an HEP to the stock computer and directs the computer's spark requests to the right coil. Timing is fixed at 10 degrees advance, you'll have to change your spark curves anyway for the 2.4. COP is supported. I also modified the hybrid adapter for COP, it now uses a different mcu (pic16f690) if you want COP, same one as the NGC adapter. I'll get the hybrid COP and NGC adapter code and schematics up this week. I also got my non-NGC car back today, so I'll start investigating those waveforms for the old 2.4 swap people.

You rock man!

I was playing at the yard today and looked at the COP setup from a V6 intrepid. They have half off Wednesdays so I stashed some things and need to go back then. I might grab 4 COP units then to play around with depending on the price. I can play around with it after that. I think we might be able to use the 2.4 plug boots with the COP units since they just have a spring that connects the coil to the plug. The main problem is that they are supposed to bolt to the valve cover to hold them steady (and on) and that would require some valve cover mods or an adapter to hold them in place...

Overall I think I am pleanty happy with the wasted spark setup so it isn't a high priority for me.

The COP setup is still wasted spark. It just has four coils to waste them over

[90TurboVan]

COP is not wasted spark. It fires only the coil that is on the compression stroke, hence, no wasted sparking.

I have my 1999 2.4 with an SRT turbo installed in an 86 L-body ready to field test your first lost spark module using the 2.0/2.4 coil that is already hooked up when you are ready to ship the first test sample.

I was just about to make up custom length wires and hook my dist up to the side of the head, but this changes everything if it field tests out. Not needing a distributor frees up lots of precious L-body engine bay space.

It also looks a lot better without that stupid distributor sticking off the side of the head. PM me with your info and we'll work something out.

Anyone got an SRT swap or new 2.4 swap for testing?

I'm in exactly the same place as you, so if there's is a need for another test car, let me know! I have a 1998 2.4, SRT turbo installed in a 1989 Daytona.

How right you are. Man this is just awesome. Way to make that distributor obsolete. A significant contribution to the TD community. Looking forward to the finished product.

I've got an SRT engine going into my Omni, bit it won't be ready to start up for a couple of months. I'm sure there's someone else that will speak up though. If not, I'll try/buy it when I can.

Me too, but it could be more than a couple months before mine is ready to start.

I'm scoping the non-NGC stuff tonight and I'll put up the timing diagram.

Definitely looking forward to this. I was going to say if you didn't have a chance, I could pull the data from my mother's 02 Stratus.

Question... would the cam sensor even be part of this whole scheme of things?? All the diagrams in this thread only include crank sensor data.

We have to use the cam sensor on NGC cars because the TD computers fire injectors in batches (1+2 and 3+4) from what I can tell. In order for the computer to fire the right injectors as well as the right coil, it has to know exact position in the firing order. Cam sensor will also be used on non NGC engines for the same reason.

i also got a srt motor going in my omni (well actually a pt motor) i will be a little while for me to i'm still working on the body restro. got the motor still collecting parts. but i also am int. in this

[90TurboVan]

Changed the NGC timing diagram on page 4 to include what I've found for the cam sensor. The cam line is the top one, and may not be completely accurate. It may need to be shifted one crank tooth to the right, not sure, but it doesn't change the synch method. I could have it tell you if your cam timing is off

[jonnymopar]

Another question: would this circuitry require a need to be clocked somehow? Maybe by tach signal?
