This tab contains parameters for setting the VTEC point & window.
VTEC Window
The VTEC window is a variable VTEC switch point based on engine speed and engine load. Usually you want the VTEC point to move higher with lighter engine load. The above screen shot shows VTEC switching at 5000 rpm when the manifold pressure is 89 kPa or above (which is close to full throttle), reducing in a linear fashion to 5800 rpm at 25 kPa manifold pressure.
Do not set the VTEC switch point too low as there will be insufficient oil pressure for the rest of the engine. As a guide do not go below 2000 rpm.
Do not set the VTEC switch point too high as the high speed rocker arm will float on the lost motion spring and damage the valve train. As a guide do not set the VTEC point higher than 6500 rpm.
VTEC Options
VTEC oil pressure For JDM engines and JDM ECUs disable the VTEC oil pressure sensor.
VTC Disable VTC for engines with locked camshafts.
P0341 This error is generated if the phase difference between the intake and exhaust cams is more than about 5 degrees. Some after market camshafts will generate this error.
Minimum Speed - is the minimum vehicle speed before the cams switch to the high speed lobe.
Secondary Intake Runner Options
The option is only available for engines with secondary intake runners. Disable the secondary intake runners if the intake manifold is replaced with a single path manifold (e.g. a supercharger manifold).
