Thanks Adamw.

Hoping to get some help from the guys that are very familiar with link g4X V8 subaru Impreza. info: own a fully build engine blok 2.1 stroker. had a V6 subaru before with almost the same setup, that was tuned on a dyno. No i m having the same engine in a V8 subaru with bigger cams 272 and new series Garret G-turbo, convert the V6 map to a V8 map. the issue when starting the car was idle properly, this turbo is smaller then my last one, but flows simmular when driving and with the bigger cams it was way off at idle. Also the idle is different on these models. V6 uses a steppermotor and a V7 a idle solenoid. same intention as last time running the engine in for 1000km and had 20 min breakin for the cams at 2000rpm. after that it is going on the dyno again. Got it so far that the it idle ok for now exept the needle is not stable enough in my opinion... maiby it is the cams but that's where i want the help/sollution if possible. The other thing is when the engine is hot 80/90 deg and i'm starting the engine it runs very lean.. after a while it wil stable itself or if i push the trottle a few times it will come back at around 14.7 AFR ealier. Who can point me in the right direction, or suggest which figurs to change? -More stable Idle, and the lean part on re-start a hot engine. I made a log to identify the wrong setting? thanks for the help. Regards Rens PC Datalog - 2024-01-13 6;36;27 pm.llgx

Ok... thanks guys.

i put complete v7 spec c jdm heads on my V6 engine full build. Trigger 1 crank original V6 toothwheel, trigger 2 cam toothwheel is v7 jdm. This is not a match Anymore between the triggers i found out a little bit later..... Is there a way to solve this within the Ecu or do i need to change the crankshaft toothwheel to v7 jdm? thanks in advance

Thanks ADAMW

Hi, hope you can help me find an answer. i am having a subaru V6 MY00 with v7 spec c heads. VVT inlet only. Bought a wiring kit for the sensors and oil control valve’s. Put the wires from the oil control direct to aux ports on the Ecu the other wires going 12v. some Ecu require skottky diodes. These are supplied in the kit but do i have to use these diodes with the G4X ecu? thanks in advance.
