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 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).
How does the SFC part of the VTEC work?
The SFC portion of the SFC-VTEC operates by “spoofing” MAP signals to the ECU, which in turn, causes the computer to either add or subtract fuel. One thing that remains uncertain in my mind is whether the ECU continues to rely upon the MAP signals at WOT (wide open throttle) or not.
Do you lose power when lowering the VTEC?
Yeah, but on a stock engine you will not only lose on mileage but also on power and drive-ability. 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.
Where is the VTEC controller on a inlinefour?
The Spoon vtec controller is a concealed unit that is controlled by the turn of a knob. The knob is located in the dash panel and features an LED light to help distinguish vtec point adjustments. The Spoon vtec controller takes full advantage of the vtec operation, allowing you to adjust the incorporation of the high-cam throughout the rpm range.

Why do you need a VTEC controller for spoon?
The Spoon vtec controller takes full advantage of the vtec operation, allowing you to adjust the incorporation of the high-cam throughout the rpm range. This is very useful for course racing where slow tight cornering is common and the need for a quick vtec engagement is necessary to help pull you out of the turn.

What is the resolution of the field SFC VTEC controller?
So many questions, so few answers… 8-Step Simple Fuel Controller allows ±30% adjustment of fuel delivery (with 1% resolution) at 1000 rpm increments from 1000-8000 rpms. (4.14.98) – The above Excel charts plot the gains/losses of the Field SFC VTEC unit.

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.
