[Xtreme pinout for evo 4+]

Yep, you wont need ecu hold power.  You will probably still need to use that ign switch wire to trigger the main relay though.  

I'm assuming ecu hold is pin 80 labeled back up supply , would that be correct

FYI, you will find more complete pinouts in the G4X manual or G4X PC Link.

 

Yes, Ign 4 is used for 2 different fans.  Evo 4/5/6 has one of the fans on different pins to Evo 7/8, so the 3 pins cover all models.

 

Ign switch is on pin 82.  The G4X manual will probably show that.  But be aware, if using a wire-in ecu and keeping the stepper motor idle valve you will need to incorperate the proper ECU hold power circuit into your wiring as per the manual.  Our plug-in ecu's have this circuit on the adapter board.  

 

Thanks Adam. 

Have converted to DBW so I won't need to worry about ecu hold power circuit is that correct

Just been looking over these pinout guides and noticed a couple of odd things. 

1st pic is 3x Ign 4 pins lined in orange is this correct 

2nd pic is ignition switch D1 lined in orange I can't find it on pin location in pic 1 

Is some one able to clarify please

Dan, did you manage to get this setup working with the subaru PWM controller?  I've done a bit digging and apparatly the PWM signal they use is 5v not 12v.  Anyone know how you can reduce the ecu's 12v aux outputs down to 5v?  Electronics baffle me,  I'm assuming the plug in G4X units for impreza's must have some sort of circuitry built in to do this.

I've gone with the jag controller insteed 

[Fuel pump & coils, injector switch (kill switch)]

If I have a switch between the relay and aux output as pictured, mainly used to immobilise fuel pump & coils/injectors using a factory unused dash switch with duel input/output

will I need to enable a pull up resistor due to lowside switching, if available on aux channel. Or will I need to use a digital channel insteed.. Xtreme+

On a G4+ Xtreme, the ABS rings will probably have too many teeth to give you working value at higher speeds.

What you may be able to do, though, is pick up on the back of the brake disc/hub on the wheel studs, for example.

This is the little bracket I made for my front wheel to pick up on the back of the wheel studs:

Do you think it would be posable to shave every second or second and third tooth off to have half or a third of the original amount remaining

Replace the subaru controller with a Jag XJ controller.

That's what I ran on my subaru before I went brushless. I also ran it with and without a cheap amazon voltage booster/regulator up to 16V for more flow.

They're easy to get under $100 and I can get you connectors if you're in the US.

Cheers for the jag controller info.. Do you have a link to the voltage booster you used handy 

[Fuel pump PWM controller]

I think you are correct, my understanding from the article is the f/p controler has a voltage step down at full load from memory I think it said aprox 10.9v supply, 

The article said the use of the relay was to take a direct feed from the battery to the fuel pump pulsing the relay via ground. 

Would a solid state relay do the same thing with out the use of the f/p controller?

[Fuel pump PWM controller]

Quick question.. In regards to a subaru PWM controller is any one able to tell me where the 2 wires labeled ecm/ecu pin 9-8 in the attached picture should be run to. 

Or would a hella solid state 20amp relay do the same job a lot easyer

Simplest way is to set up one of the Aux outputs (or a spare Ign/Fuel output) as Tacho.

Cheers mate.. You accepted my FB friend request do you mind if I directly message you for querys etc.. (clicked to who you are legnum appreciation, owners etc FB)

Had Some success today removed that wire and from the crank trigger signal and scoped the triggers again and looked normal without any odd spikes and managed to make it run. Thanks for your help Adam was greatly appreciated.  

Currently wiring up a link xtreme In my legnum. I have also removed IFS and spliced off the crank signal wire to retrieve a tach signal, apon reading this which I'm glad I did I see I'm also going to have to remove the white wire of the crank signal.. My question is how did you go about getting another signal input for the tacho

Keen to know how you went as Ive just started the same process on my vr4
