Since VTEC-E is not performance oriented, the VTEC cut-over is much earlier on these engines.

VTEC-E Valve Timing Change Conditions are:
Engine Speed : 2,500 RPM minimum (3,500 RPM typical) - Determined by engine load (MAP sensor output)
Vehicle Speed : 5kph (3mph) minimum
Water Temp : -5.3 C (22 F) minimum
