Utilize Twin Independent Variable Cam Timing Control in Modern Engine Swaps

Holley EFI has designed a system to control the Ti-VCT function for Ford Coyote engines that have been swapped in non-factory applications. When compared to an engine with the camshafts locked in place, gains of 90 ft.-lbs. of torque at 3700 RPMs can be seen. Main Harnesses come terminated with Ford TPS and IAC connectors, making it easy to convert from a DBW throttle body to a cable throttle body, if desired. High-speed data transfer and diagnostics are possible by the CANBus style communication between a Holley EFI ECU and the Ti-VCT control module.
