Frequently asked questions

Does the ECU control the original VVT?
Yes. The intake and exhaust timing are fully adjustable.

Can an ECU be used in an engine that has been installed in another car?
Yes. In this case, the vehicle-specific wiring (12 V, fuel pump, accelerator pedal, etc.) is done separately.

Does the ECU support anti-lag?
Yes. Syvecs ECU is used by several top level rally teams.

Is the launch RPM adjustable?
Yes.

Is Flex Fuel supported?
Yes, and the ethanol content is displayed on the instrument cluster.

Can AWD operation be adjusted?
The reported torque of the engine affects AWD, but for full control, a separate AWD controller is recommended.

How do I change maps?
With OEM cruise control buttons. Cruise Cancel also acts as a rolling antilag activation.

Which OEM features are not available?
Pre-Collision System and Lane Assist are not supported.

Can the original BOV be replaced?
Yes, you can use any blow-off valve.
