VARIABLE VALVE CONTROL (VVC)
The AEM Infinity system supports Nissan’s 2 cam variable valve timing equipped engines (VQ35DE) and
4 cam variable valve timing equipped engines (VQ35DE-RU). The base calibration is configured with base
VVC settings that may need adjustment.
VVC Enable
To the right is the “VVC” page of the setup wizard configured for a 4 cam VVC equipped engine
(VQ35DE-RU). Two cam VVC equipped engines will only use “VVC1A” and “VVC1B”.
VVC Cam Sync
Cam sync is similar to ignition sync on an engine. Before setting cam sync, be sure VVC cam
assignments are set properly. With all VVC channels disabled (VVC enable boxes unchecked), start the
engine. The intake cam(s) should be at a parked retard position and the exhaust cam(s) should be at a
parked advance position. These points will serve as 0 timing reference for the VVC system. Adjust cam
sync values now until each cam timing registers as close to “0” as possible. The provided VQ35DE-RU
values should only require minimal adjustment.
Lowside Setup:
The lowside outputs should be configured as follows for
proper VVC operation:
VVC1A = Lowside 3
VVC1B = Lowside 5
VVC2A = Lowside 6
VVC2B = Lowside 8
VVC 1 Frequency = 300 Hz
VVC 2 Frequency = 1000 Hz
