Is a VTEC a turbo?
Honda’ s VTEC TURBO is a technology that efficiently uses every last drop of gasoline, through a combination of turbo charger, direct injection system, and variable valve timing mechanism. Through VTEC TURBO and hybrid systems, Honda strives to combine driving pleasure with environmental performance.
Can VTEC stay on?
Correct. It’s not unsafe – but it isn’t optimal either unless it has been dyno tuned for the best proven VTEC engagement point. It’s also retarded to run a VTEC engine without a proper VTEC ECU.
What does APEXi VAFC do?
APEXi VAFC II – Vtec Controller Modifies manifold pressure signal and alters VTEC engagement point on Honda VTEC engines; Vacuum Fluorescent Display (VFD). APEX introduces the first digital fuel computer that combines fuel computer functions with a VTEC engagement controller.
At what RPM does VTEC kick in?
It engages anywhere between ~2300-3800 rpm, depending on conditions. And the engagement point will generally not be as noticeable as with DOHC VTEC engines. Thag, Generally, at higher rpm, it is more efficient to open the intake and exhaust valves for a longer time, thus the longer duration and different grinds.
What is Apexi AVCR?
The AVCR is a digital boost controller that allows the user to modify the boost pressure level on turbocharged vehicles. This feature allows boost response adjustment for varying turbo sizes.
What happens when VTEC kicks in?
Ever wonder what “VTEC kicking in” actually means? Like most other variable-valve timing systems, VTEC varies oil pressure to shift between different cam profiles. At higher engine speeds, the cam profile allows greater valve lift, which allows more air into the cylinder. This helps generate more horsepower.
What is the purpose of a boost controller?
A boost controller is a device to control the boost level produced in the intake manifold of a turbocharged or supercharged engine by affecting the air pressure delivered to the pneumatic and mechanical wastegate actuator.
What does the VTEC system in a Honda engine do?
Image Gallery: Engines The VTEC system in Honda engines allows the engine to have multiple camshafts. See more car engine pictures . If you have read How Car Engines Work, you know about the valves that let air into the engine and let exhaust out of the engine. You also know about the camshaft that controls the valves.
What can a field of Japan VTEC controller do?
Join Discussion…… Field of Japan has put together a nice little VTEC controller which does everything a VTEC controller should do, plus it adds the powerful capability of allowing the tuner to adjust fuel delivery up to ±30%, in 1% increments. The fuel numbers can be set at eight points on the rpm band (1000, 2000, up to 8000rpms).
Why are VTEC controllers not a good idea?
Lowering of VTEC engagement must be done in combination with a proper remap with at least some mild breathing mods. Otherwise you will lose power. And that’s why the controllers aren’t so usefull; when you’ve got a mappable ECU you can adjust the VTEC point on the ECU and you don’t need the seperate controller.
What does setting VTEC at 3, 000 rpm do?
Since the vtec cam lobe is much taller, it can now provide more air and duration the motor needs to keep making power @ higher RPM. Now think about it. What does setting VTEC at 3,000 rpm do? It makes a cam lobe designed to work well at HIGH rpm to work at LOW rpm.
