Car Forum / Nissan / Nissan Z Cars / January 2005'79 260Z dizzy to Wolf 3D EMC
Hello everyone. Now that all that spam has abated I'll pose my question again but slightly modified. I have a '77 260Z that I've installed the EFI system out of a '79 280ZX plus the dizzy from the ZX which has the E12-80 ignition module on the side. Now I have a Wolf 3D version 3 engine management computer and I need to know how to connect the wire from the EMC crank trigger input to the dizzy. I was thinking of taking the 2 wires from the internal dizzy reluctor to the crank trigger input on the EMC and then connecting the EMC ignition coil igniter output to the ignition module (E12-80) input. I have heard that it has been done successfully. Anyone here know the wiring details? Thanks in advance for any help offered. Cheers.

Why would you do this? Just get the right parts. If you really want to make some power, ditch the factory AFM type EFI systems, use a map sensor system like SDS or Haltech and have someone fabricate a new intake manifold for the car. Until you do this, you aren't going to gain much if anything. See: http://atlantaracing.tripod.com/280zmods/280intake.html Follow through the pages and see what I ended up with, what worked and what didn't.

[quoted text clipped - 4 lines] > >Is this the 300ZX based hot wire AFM system? No. The wolf doesn't need or use the AFM. It uses a throttle position sensor, a Oxy sensor, a air temp sensor, a water temp sensor and the manifold vacuum. It controls fuel and ignition too if you have a crank angle trigger. The dizzy can be used as the crank angle trigger if it is modified by welding it locked so there is no mechanical or vacuum advance (which I've done) >> and I need >> to know how to connect the wire from the EMC crank trigger input to [quoted text clipped - 7 lines] > >Why would you do this?

I've been racing this car for years with tripple Webbers very successfully, but now I'm too old and on a pension so I want to de-tune the car to make it safer and more economical to drive for my grand daughter. >See: >http://atlantaracing.tripod.com/280zmods/280intake.html > >Follow through the pages and see what I ended up with, what worked and what >didn't. Nice. I would do it your way if I was younger and had the finances :-( Thanks anyway Steve Cheers No Spam Please rogdon2004@NOSPAM.hotmail.com Remove the obvious spamtrap >>Is this the 300ZX based hot wire AFM system? >> [quoted text clipped - 4 lines] > is modified by welding it locked so there is no mechanical or vacuum > advance (which I've done) OK, I assumed it was the JWT (Jim Wolf Technologies) Z31 hot wire AFM system. > Because of my budget and because I know it can be done. If the system is looking for a mag trigger input, just hook it to the pickup coil and the ignition output from the box to the module. The module is marked positive and negative inside the dizzy and the external 2 connectors just go to the coil hot and ground. > I'm not after more power.

It's going to run better and there isn't going to be much if any power lost over aftermarket EFI using the stock intake manifold as it's the bottleneck.

I should have been a bit more specific I spose. The Wolf 3D is made by "Advanced Engine Management" here in Australia and is very much like the Haltech EMC you mentioned before http://www.wolfems.com.au/home >> Because of my budget and because I know it can be done. > >If the system is looking for a mag trigger input, just hook it to the pickup >coil and the ignition output from the box to the module.

Perhaps I should use this instead of the '79 dizzy setup? If so do you have any experience with the Crane? The optical trigger has three wires. >> I'm not after more power.

I bought the complete EFI system out of a '79 280ZX but the computer was dead. That is why I decided to buy the Wolf 3D from a friend for $400 under new price. He had bought it a couple of years ago but never got around to installing it.

I'm not much of a fan of those crane ignitions. SignatureSteve http://www.atlantaracing.com |
