You're a bloody wizard, Adam. I swapped the cam types for D1 and D2 and now the AVCS works like a dream. I can't believe it was something so simple. Thank you again for your help!

Thanks for the insight and rapid reply, Adam! I'll give that a go and see how it responds. This is unrelated to the AVCS issue but my ethanol sensor (genuine link), wired to DI7 doesn't want to work. I'm 99% sure that the wiring is correct but it usually shows "ERROR" or that the sensor is "off". Power is wired to the same switched 12v as the VVT solenoids. Ground is spliced into "sensor ground" on the ECU and the signal is wired to DI7. Thank you in advance, EJay

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
