EFI Hardware Hall Effect Distributors
About
EFI Hardware sell a number of single and dual Hall Effect distributors to suit a number of applications. The dual sensor versions are a good way to update an old engine to have a trigger system that supports sequential injection.
The design appears to be based on the Holden Commodore VT V8 distributor.
Wiring
For the models listed in the below image.
Distributor Wiring | Function | Haltech Wiring |
Red | 12V+ | Red in Trigger 4-core |
Black | Signal Ground | Blue in Trigger 4-core |
| Green | 8x signal (Trigger +) | Yellow in Trigger 4-core |
Blue | 1x signal (Home +) | Yellow in Home 4-core |
In the Trigger 4-core the Trigger -ve green wire on pin B5 is not used. We can instead move this pin over to the Home + (B2) ECU pin. This then allows all 4 required connections to be available in the single Trigger 4-core cable.
Follow these steps to perform the pin swap:
1. Unlock the smaller 26-pin (B) connector by pushing in the white tab until it clicks. Two smaller white tabs will pop up on the other side.
2. Remove Pin 2 (yellow) and insulate this pin. It will not be used.
3. Remove Pin 5 (green) and insert it into Pin 2.
4. Push the 2x white lock tabs in until they click.
5. Now wire as follows
| Distributor Wiring | Function | Haltech Wiring |
| Red | 12V+ | Red in Trigger 4-core |
| Black | Signal Ground | Blue in Trigger 4-core |
| Green | 8x signal (Trigger +) | Yellow in Trigger 4-core |
| Blue | 1x signal (Home +) | Green in Trigger 4-core |
Configuration
Clockwise Rotation Distributor Models
Because the Sync Pulse occurs after the Trigger Pulse for cylinder#1 rather than before it means the TDC Offset will need to be moved by 7-cylinders worth of crank rotation. The sheet tells us the Falling edge occurs at 60 deg BTDC. Now we need to use a little math to figure out the correct offset.
2x crank rotations = 720 deg
720 deg divide by 8 cylinder = 90 deg per cylinder.
90 deg x 7 cylinders = 630 deg
Add the original 60 deg angle and we get 690 deg BTDC.
So the following configuration should be used.
Counter-Clockwise Rotation Distributor Models
This version has the Trigger at an appropriate angle on the Rising edge at 75 deg BTDC. Using the same process as above we get a TDC Offset of 705 and the following configuration should be used.
