Background:
For the stock D-Jet, the ECU gets the signal to fire the injectors from a set of mechanical breaker points inside the base of the distributor. There is nothing wrong with the factory method except for the fact that if you want to run the D-Jet injection, you have to keep the factory distributor...not anymore (IMG:http://www.914world.com/bbs2/html/emoticons/smile.gif) I have successfully been able to electronicly trigger the ECU from a pair of optical sensors inside of the billet Mallory distributor....so far I have only put a few miles onto the car with this setup and I don't know how it'll work when the temperature is much higher (currently it is 45° outside.....) it's ugly right now, but give me some time to clean it up... (IMG:http://www.914world.com/bbs2/html/emoticons/smash.gif) (IMG:http://www.914world.com/bbs2/uploads/post-2-1106100569.jpg) So for my ignition, I have the Mallory distributor, accel coil and new 8.5mm plug wires....starts right up and idles fine, but I might install a CDI box anyways... |

the wheel on the shaft is just a bronze flanged bushing that I filed down.... no seperate PCB board, it's just a few resistors and a transistor....the transistor acts like an electronic valve...when the wheel blocks the light from one side of the sensor, the transistor gets "turned" on which allows a ground path to flow from ground to the ECU, triggering the ECU to fire the injector...the transistor is sorta like a relay, but it's done with no moving parts inside of it.. the red Unilite sensor is just as simple in operation.....only 3 wires and about $2 in electronic parts (thing costs from $90 to $120 at the stores) these are very simple as well brown wire ground, red is power (+ on the coil), green goes to the (-) coil...when the car is turned on, the green wire has 12 volts as does the red wire..the coil is "even" and happy .....when the rotor goes past the "lights" and has an open window, the 12volts going to the green wire is turned off, the coil is no longer even and the windings freak out releasing the energy within producing spark......sorry for the simple simon description, LOL |
