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

That pic only showes one channel hooked up. Remember you will have to build two circuits to control both coils.

Good luck to anyone attempting to build this circuit!

That would've been nice when I had my E-manage Ult. hooked up... have you tested it yet with success?

Yes I have tested everything out and it works fine. Its currently not installed on the car. I just hooked everything up to test it. I need to get an enclosure for the circuit board. I will get some more pics once its installed.

Good job! Always wanted to see this done. You should include this in a wiki with that diagram, so that we never lose that picture.

Ok guys, an update on this ignition system. The motor WILL run with this setup but I kept having a problem of not getting a hot enough spark. The car would run fine until I would get into boost and the spark couldn't ignite the fuel and the car would miss like hell.

I tried to fix the problem and have come to the conclusion that the transistor pack is causing the problems. Not sure if mine isin't working properly or if it wont work with my set up. If anyone wants to continue to try and get this system working I would suggest trying a transistor pack first and if that wont work possible trying a transistor that is used for megasquirt. The VB921 I believe.

vb921 will have the same result. if you read back in the MS issues, you will find that.

I know that people were having some problems with it, but it might have worked better than that transistor pack I used. I would only get a few pounds of boost before it would start to miss. I close the plug gap some and it helped but didn't fix the problem. The vb921 may not work perfect but it may give better results then what I had.
