How does VTEC work in a Honda engine?
As engine speeds rise, a piston inside the rockers is pressurized with oil, locking all three cams together to increase valve lift. This is where that signature “VTEC kicking in” sound comes from. Now next time you “get into VTEC” while driving your Honda, you’ll know exactly what’s happening inside your engine.
Why do I need to Reset my ECU on my Honda Civic?
After you install aftermarket parts, resetting the ECU will help your car’s computer “learn” and accommodate the new parts. Sometimes a faulty check engine light may appear, so resetting the ECU can make it go away. If any of these problems are affecting your Civic or Accord, it is very simple to reset the ECU.
How does Honda variable valve timing system work?
VTEC is a type of variable valve-timing system developed and used by Honda. It stands for V ariable Valve T iming & Lift E lectronic C ontrol. Like most other variable-valve timing systems, VTEC varies oil pressure to shift between different cam profiles.
How does the Honda CRV VTEC oil solenoid work?
The VTEC system increases the amount of intake valve lift for increased power. It accomplishes this by turning a control solenoid ‘ON’ to allow oil pressure into the VTEC control passages to apply pins that will lock the intake rockers. When the oil pressure is present, the pressure switch signal will go high.
Where to set the VTEC on a Hondata?
Set the VTEC point to the intersection of the high speed cam and the low speed cam. Generally if there is a sudden increase in engine output immediately after the cams switch then lower VTEC.

How many camshaft profiles do you need for VTEC?
The camshaft profiles are switched depending on engine rpm and load, usually from 2500 rpm to 6500 rpm. The main effect on tuning of VTEC is that there are usually two copies of every major table – one for the low speed camshaft, one for the high speed camshaft.
