ashesman Posted January 15, 2008 Report Share Posted January 15, 2008 You may be able to find a base setup for your engine, but I think you will have to configure it. G1 ECU's were usually sold setup ready to go for a particualr engine (still need tuning), so you should already be pretty close.

ashesman Posted January 17, 2008 Report Share Posted January 17, 2008 Subaru firing order is 1,3,2,4. Wire it how the diagrams show and all should be OK... You will have to look into why your FP doesn't work. The FP should run for a few seconds at key on then run while the engine is running.

ashesman Posted January 17, 2008 Report Share Posted January 17, 2008 You should not join your ignition wires together on a LinkPLus G3. If you have a four coil engine then refer to the diagram labelled "WRX/RS Four Coil - LinkPlus". The coils are wired in the firing order but not necessarily with ig 1 - cyl1. Refer to the manual about this. Wire your injectors exactly the same as the ignition. Until you get it running, don't worry about the wiring of your injectors as it will not stop the engine from starting. Check in PCLink that the "Sync/Cyl Err" is not counting up while the engine is cranking and that a stable RPM value is shown. You will need to make sure your ECU has the correct sub-board fitted for your engines triggering. Does it have the same crank angle sensor arrangement as a V1-6 Subaru or V7-9?

ashesman Posted January 20, 2008 Report Share Posted January 20, 2008 Are you using the correct version of PCLink? You will need to use V2.5 for an older ECU, not PCLink 3. You should be able to see all adjustments that would be available with a tuning module...

ashesman Posted January 21, 2008 Report Share Posted January 21, 2008 To be honest I am out of ideas for you to try. Those diagrams I sent have been used for years now to wire those ECU's to Subaru's so there are no mistakes there. Wire it how the diagram says and it should be OK. IF not, start doing some diagnostic work with a timing light to see when the cylinders are firing. Your ECU is set up for V1 to 6 crank/cam sensors, not V7-9 sensors, so make sure you are not using a V7-9 engine. I believe that V7 started in about 2000. If you are completely stuck you may have to get your car to one of our dealers or a specialist for some help.

ashesman Posted January 22, 2008 Report Share Posted January 22, 2008 Its not actually the sensors, but the locations of the teeth on the crank and cam pulleys. You should know if your engine came out of a car that was before or after about 2000.

ashesman Posted January 23, 2008 Report Share Posted January 23, 2008 So it would have Subaru V1-6 triggering. When you get your new G3, just select Subaru V1-6 triggering and enter the correct firing order. Wire coils Ign1 - cyl 1, 2 to 2, 3 to 3 4 to 4 and it will all just go!!!
