Hi all, I hope everyone is enjoying their weekend. I'm experiencing some issues getting the AVCS on my motor to function correctly. I've fitted a V8 EJ207 motor into my 1999 WRX that is being powered by a Link G4+ V5-6 WRX ECU. With both solenoids set to 300hz, only the RH side works but will surpass its target greatly, causing the engine to misfire. However, if I tinker with the solenoid frequencies, I can get the LH side to work but same deal, it will surpass its target and the RH side will cease to operate. I've tested each solenoid using the "test pwm" function and both solenoids are audibly clicking. I've carried out a cam angle test on each side and here are the numbers I received: LH cam angle 1 - 4: (378.4, 557.3, 18.3, 199.1) RH cam angle 1-4: (195.8, 375.2, 556.7, 16.5) Attached is my tune file, a log of the fault during operation (at 300hz on each solenoid), 2x logs for each cam angle test and a trigger scope during engine operation above the RPM lockout for the VVT. I do have both solenoids wired to the same 12v switched ignition source, I don't know if this could be the cause but I think it is strange that the solenoids both work with different frequency settings and never at the same time. Thank you and kind regards, EJay Proper Tune 3.1.pclr LH cam test.llg Log during fault.llg RH cam test.llg Trigger Scope 3ishk rpm.llg

Hello everyone, I am having some troubles with getting my v9 EJ207 to run on the modeled fuel strategy. I can get it to run on the stock ECU and I have run the car on the traditional mode as well. The car is basically stock aside from Injector Dynamics 1000cc injectors and a walbro 255lph pump. I am using the "spec-c" intake mounted IAT, factory ECT and factory V9 MAP sensor. I have a PLX SM-AFR wideband (not yet hooked up to the ECU, I have lambda corrections turned off so I assumed this will not affect the ability to run the car). As far as the map goes I have left everything as it comes from LINK aside from adjusting the PS voltage code, Tacho fix, switched to modeled in the "Fuel Main" tab added injector size info, latency and injector short PW adder tables. Number of cylinders is correct, engine size is correct, VE table is the LINK factory table, I'm running 91oct fuel, so I left the fuel density as from the factory as well. Fuel pressure is 43.5 as well. I can only get the car to run when I size the injectors at ~400cc, as I raise the injector size, the lamda leans out. Alternately I can lower the fuel pressure to ~20psi and it will let me raise the injector size closer to the true size, but my factory fuel pressure regulator is not a 20psi regulator. Does anyone have any pointers? I have included the map I am working on. I'm much more familiar with megasquirt and I'm sure I am overlooking something easy, any help is appreciated! 1000cc Modeled WRX V9 G4+ Xtreme Plugin.pclr
