#3528, "Emanage Blue Ignition FIX" Nov-28-07 10:51 AM by SilvrEclips
Ok guys, I know most of you perfer to use megasquirt now but for those of you who still like the emanage unit. We now have ignition control. I searched around for days/weeks trying to figure out how to get control over ignition timing on a 2gnt. I found not one person who has been successful. I started researching how our cars ignition works and compared it to the 4g63 ignition. Both systems are a wasted spark ignition, the only difference is that our ecu grounds the coils to make them fire, where as the 4g63 sends a 12v signal to the transistor pack which grounds the coils making them fire.
We are basically making our ignition system work like theirs. With some help I have designed a circuit so that when the ECU grounds the coil to send spark this circuit sends out a 12v pulse. We take this pulse and run it through emanage then out to a transistor pack stolen from a 4g63 motor. The transistor pack then grounds the coil making the plugs fire.
PARTS:
Predrilled circuit board Four 10K resistors Four 1K resistors Two 2N3906 transistor Wire Soldering gun Case for circuit
Emanage Ignition harness 4g63 Transistor Pack
Mitsubishi has used several different transistor packs. I used the J722T 7-pin. Not sure if other transistor pack could be used, you would have to try them. Here is how to hook the pack up:
Pins: Oc1 - Output to coil pack ch.1 IB1 - Input from Emanage ch.1 Vb - 12v source Tac - Not used Gnd - Ground IB2 - Input from Emanage ch.2 Oc2 - Output to coil pack ch.2
These are the jumper settings you will need to use: Jp1 - 1&2 Jp2 - 1&2
