Shane Posted August 17, 2020 Report Share Posted August 17, 2020 Hi, Chasing any information about this conversion of a ej207 with single avcs into a 2000 model GC8, I’m sure it’s been done many times just haven’t found the information I’ve been looking for. Im running a Link G4+ pnp wrx v5-6 If anyone has any wiring diagrams or information or a link to where I might find some that would be very helpful. Thanks Shane Quote Link to comment Share on other sites More sharing options...
neil brown Posted August 17, 2020 Report Share Posted August 17, 2020 To run avcs you will need to fit newage timing wheel to crank to suit camshaft timing wheel And set the ecu for newage timing config then move some pins around as camshaft sensors need to be on di 1 and 2 Quote Link to comment Share on other sites More sharing options...
Shane Posted August 17, 2020 Author Report Share Posted August 17, 2020 Thanks for your information but not sure what you mean by new age timing wheel ,what’s wrong with the original ej207 one? Quote Link to comment Share on other sites More sharing options...
neil brown Posted August 17, 2020 Report Share Posted August 17, 2020 Classic timing wheels 92-99 Have different teeth set up think it’s a 6/7 set up newage timing wheels 20000-2006 have 36-2-2-2 teeth set up to suit cam shaft wheel and Avcs set up Quote Link to comment Share on other sites More sharing options...
Shane Posted August 17, 2020 Author Report Share Posted August 17, 2020 But I have the 2002 ej207 front crankshaft timing gear on, not the timing gear from the gc8 engine. Quote Link to comment Share on other sites More sharing options...
neil brown Posted August 17, 2020 Report Share Posted August 17, 2020 Current set is classic gc8 which uses 6/7 timing gears can the current link wrx5/6 ecu run a newage set up as its currently set up for pin out for a classic Quote Link to comment Share on other sites More sharing options...
Shane Posted August 17, 2020 Author Report Share Posted August 17, 2020 Ahh now I think I understand your talking about the ecu, and I’m not sure... where would I look to find that information? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 17, 2020 Report Share Posted August 17, 2020 Yes it can be done but you need to add/change some wiring. You will need 2 expansion looms. The original V5/6 engine has just one cam sensor at the front connected to trigger 2. The EJ207 still has a cam sensor at the front that connects to trigger 2, but also, two new cam sensors at the back for the AVCS. So you need to run new wires to these back to the ECU. Also, the two AVCS solenoids at the front will need switched +12V supply and two wires run back to the ecu. The Cam sensors at the back need to connect to DI1-4 which are already used for other functions. So to free up DI1 & DI2, move the start signal wire from DI1 (pin B135-2) to DI 5 on the expansion connector, then connect the LH back cam sensor to DI1. Move the power steering signal from DI2 (pin B135-1) to DI6 on the expansion loom, connect the RH back cam sensor to DI2. The AVCS solenoids need to connect to Aux 1-4 which are already used for other functions so these need shuffling too. The suggested option is to move the fuel pump wire off Aux 1 and move it to ign 7 on the expansion connector, then connect the LH AVCS solenoid to Aux 1. For the RH solenoid, move the AC clutch wire off Aux 3 to Ign 8 on the expansion connector, then connect the solenoid to Aux 3. If you are using the EJ207 idle valve that doesnt need any new wires but needs a different connector etc. If you are using the EJ207 idle valve then that wiring will need changing a little too.

Shane Posted August 18, 2020 Author Report Share Posted August 18, 2020 That’s just what I needed thank you so much Adam. Yes I will be using the EJ207 idle valve is there much to change there? Quote Link to comment Share on other sites More sharing options...

The original stepper motor has 6 wires, 2 x 12V supplies (yellow I think), then 4 x aux outputs - Aux 5,6,7 & 8. The new valve only has three wires - a 12V, a ground and an aux. So the 12V and Aux are already there, for the ground you can just connect to the block or manifold. Quote Link to comment Share on other sites More sharing options...
Shane Posted August 19, 2020 Author Report Share Posted August 19, 2020 Thanks again Adam , which of the aux wires do I use or doesn’t it matter? One other thing I have done the TGV delete can I use Some of those wires for the extra cam sensors and AVCS solenoids? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 19, 2020 Report Share Posted August 19, 2020 You can use any aux for the idle valve. 10 hours ago, Shane said: One other thing I have done the TGV delete can I use Some of those wires for the extra cam sensors and AVCS solenoids? The V5/6 didnt have TGV so doesnt have any pins assigned to those functions. Im not sure how you would use those wires for anything unless they are long enough to reach from your solenoids all the way back to the ecu plug.

Shane Posted August 22, 2020 Author Report Share Posted August 22, 2020 Just wanted to use the shielded wires that are already run in the harness On the EJ207 and remove them from the two plugs where they terminate Put them in their own deutsch plug and run them through the guard to the ecu . Just thought it would be easier than trying to fit more wires through the fire wall and that wiring in the guard leads straight to the ecu. cheers Shane Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 22, 2020 Report Share Posted August 22, 2020 Ok, should be fine. As long as you confirm the wires you are going to use just go straight through and arent spliced to anything else in the loom on the way through. Quote Link to comment Share on other sites More sharing options...
Shane Posted August 24, 2020 Author Report Share Posted August 24, 2020 Can you tell where the other two wires from the rear cam sensors are wired to? Or is it one wire from each sensor to DI1 and DI2 after I move the others and the other two wires from cam sensors to ground? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 24, 2020 Report Share Posted August 24, 2020 Yes, the positive goes to the DI and the -ve to sensor ground. Quote Link to comment Share on other sites More sharing options...

Shane Posted August 30, 2020 Author Report Share Posted August 30, 2020 Hi, You said (Move the power steering signal from DI2 (pin B135-1) to DI6 on the expansion loom, connect the RH back cam sensor to DI2.) But DI6 isn’t on the expansion looms is there another one I can use? cheers shane Quote Link to comment Share on other sites More sharing options...
Shane Posted August 30, 2020 Author Report Share Posted August 30, 2020 Can I use DI7? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 30, 2020 Report Share Posted August 30, 2020 Sorry, yes, DI 5,7,8 or 9 will do. Quote Link to comment Share on other sites More sharing options...
Shane Posted August 30, 2020 Author Report Share Posted August 30, 2020 Thanks again Adam. One other thing the pressure sensor on the throttle body is there a way to wire it in as I don’t remember the old engine with one? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 30, 2020 Report Share Posted August 30, 2020 I suspect that is the MAP sensor? Im not particularly knowledgeable on the Subaru's, but your original one is probably on the strut tower or firewall. You can either keep your original one or move the wires from the original to the new one. Quote Link to comment Share on other sites More sharing options...
Shane Posted August 30, 2020 Author Report Share Posted August 30, 2020 No worries will look into it thanks. Will I have use the V7-9 start up base map or continue with the V5-6? Quote Link to comment Share on other sites More sharing options...
neil brown Posted August 30, 2020 Report Share Posted August 30, 2020 Are you still running coil pack on inlet or 4 coil on plug What injector sizes are you running V5-6 are side feed 440cc V7-9 sti are top feed 565cc Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 30, 2020 Report Share Posted August 30, 2020 I would stick with the V5-6 map as that will match the bulk of your pinout. Open the V7-9 map up side by side and copy across any of the AVCS stuff. Quote Link to comment Share on other sites More sharing options...
