Description

Holley Dominator® EFI Vehicle Management Systems are designed for non-emissions street and racing applications. They offer nearly unlimited capabilities to control power adders, inputs, or outputs, making them suitable for turbocharged, nitrous-injected, or water-methanol injected engines. These systems can also control GM 4L60E and 4L80E transmissions, Ford AODE and 4R70W transmissions, and two drive-by-wire throttle bodies. They feature integrated dual-channel wideband oxygen sensor controls, extensive inputs and outputs for data acquisition, individual cylinder fuel and spark control, and 1-7 Bar MAP sensor capability. Other features include self-tuning fuel table strategy, "Quick Start" strategies, knock control sensor inputs, and the ability to store and select between four calibrations. The ECU is fully potted and can be mounted in the engine compartment or interior. It includes 4 GB of internal data logging memory. The system also offers 8-stage nitrous oxide control, integrated water/methanol injection control, and turbocharger boost control.
