4worldlovers: Introducing the next generation of Holley EFI Dual Sync Distributors, the new design features an improved shutter wheel, high-quality dual Hall Effect sensors, and an MSD cap and rotor! While these distributors are designed to be used primarily in sequentially injected installations, you can easily use them as a crank trigger for TBI system also. The precision machined shutter wheel design ensures accurate timing, even at very high engine speeds. The Gen 2 Dual Sync also included a QPQ coated shutter wheel for superior corrosion resistance, and the wheel has been pinned and welded to the shaft for increased reliability. These distributors can also be used with other EFI systems that support Hall Effect crank and cam sensor inputs. Do you need to a bronze gear for your billet cam? No problem, these distributors maintain MSD shaft diameters, making it easy to source a bronze gear!

Includes both crank and cam sensors to support sequential EFI operation

Hall Effect sensor design provides precise timing control and noise immunity

Precision machined shutter wheel designed for improved accuracy at extreme engine RPM

Shutter wheel is pinned and welded to distributor shaft for superior reliability

Dominator EFI Vehicle Management Systems are intended for all engine applications, from street to unlimited high-end racing applications. In addition to the transmission control, drive by wire, and dual wideband oxygen sensor options, Dominator systems have nearly unlimited capabilities to control any power adder, input, or output you can throw at them. Need to run a turbocharged, nitrous injected 8 cylinder running water-methanol injection? No problem with Dominator EFI. How about control a 4L60E transmission as well as the fuel and spark on your street rod? No problem. There are also enough inputs and outputs to allow the Dominator VMSs to serve as their own data acquisition and control module. The Dominator VMS will eliminate the need for additional controllers as they are all contained in this one unit. The only thing limiting the Dominator Vehicle Management System is your imagination!

Ignition Plug and Play with GM LS engines (non-VVT), GM HEI, Ford TFI, Coyote (non-VVT), 4.6/5.4 Mod Motor, Late Model HEMI and magnetic and hall effect trigger. Custom settings can be configured to allow for use with many other applications

Integrated electronic transmission control – Operates GM 4L60E and 4L80E transmissions, Ford AODE and 4R70W with more to come in the future

Integrated drive by wire throttle body control – Can control two drive by wire throttle bodies. Compatible with a number of DBW throttle bodies including GM, Chrysler, Ford, and Nissan

Integrated dual channel wide band oxygen sensor controls – For monitoring both engine banks (NTK or Bosch sensors)

Extensive amount of inputs and outputs allow for limitless combination of options. Allows for unit to be used as a complete data acquisition system as well

Twelve sequentially driven 8:2 peak and hold injector drivers, capable of driving up to 24 low or high impedance injectors as a standard feature. Multiple staged injector strategies

Twelve channel Distributorless Ignition (DIS) outputs capable of directly driving “Smart” ignition coils or Holley DIS coils. Will drive 2 wire coils with the addition of PN 554-112 high current coil driver module

Speed density, Alpha-N, Alpha-N Combination, and VE fueling strategies – Tuner has the option to select from a variety of load sensing strategies to meet their engine requirements or tuning preference

Individual cylinder fuel and spark control allows you to unlock your engine’s potential

Unique lb/hr based fueling strategy greatly simplifies and commonizes tuning

Advanced idle, closed loop, and enrichment strategies allow for very stable engine operation

1-7 Bar MAP sensor capability – For naturally aspirated or boosted applications

Fuel Map and Learn Function Smoothing – Helps to smooth rough areas of the maps

Self-tuning fuel table strategy greatly simplifies tuning process – The more you drive it, the more it learns

Allows for use of common OEM sensors as well as custom sensor calibration input

Two channel knock control sensor inputs for both one or two wire knock sensors

3 Rev Limiters – Choose between 4 options for each: Fuel Only, Spark Only, Fuel and Spark, or Soft

Traction Control – Allows power reduction via timing, nitrous percentage or boost (Requires Davis Technologies Holley Module)

Store and select between four calibrations with Multi Map Selector (Part Number 558-407)

ECU is fully potted and can be mounted in the engine compartment or interior – See images for dimensions
