Dual Throttle Body EFI Systems

Dual Throttle Body EFI is here, and it's been made as simple as possible!
Based on Holley Terminator X electronics, Jenvey throttle bodies, CB Performance intake, linkage, and air filters, a high pressure compact fuel system and our many years of air-cooled VW fuel injection experience!

TERMINATOR X AND X MAX FEATURES AND BENEFITS
- Plug and play engine control for most domestic V8 Engines
- Genuine Bosch LSU 4.9 Wideband Control (Will not work with LSU 4.2 Oxygen Sensors)
- On-Board Diagnostic LEDS for: ECU Power – Engine Run – Wideband Status – TPS Calibration – Crank Signal – Cam Signal. Allow you to identify any Critical engine issues at a glance
- Built in 1bar MAP Sensor, vacuum hose adapters included (1/8th – ¼ and 3/16ths) - or for Boosted applications, you can disable the internal MAP sensor, and utilize an external MAP Sensor, the harness comes with the connector terminated, making the installation a snap.
- Plug and plug ignition capability with Dual Sync and HyperSpark Distributors, adapter 558-323 required for HyperSpark Distributors.
- 4 Inputs – 12v, Ground, 5v, and Frequency, for things such as additional pressure sensors, or activation triggers for nitrous activation, or a trans brake (Fuel and Oil Pressure Inputs are pre-terminated)
- 4 Outputs – Ground, PWM - , for accessories such as; fans, boost control, nitrous control, IAC Kit, and More
- Boost Control – Boost vs Time, Boost vs Gear, Boost vs RPM, Boost vs Speed, Boost Safeties
- Boost Control – Boost vs Time, Boost vs Gear, Boost vs RPM, Boost vs Speed, Boost Safeties
- Nitrous Control – Single Channel of Wet or Dry, Progressive or Non-Progressive, Rich/Lean Safeties, and target Closed Loop AFR
- Advanced Tables – 4x 1D Tables, 1x 1D per Gear Table, 4x 2D Tables, 1x 2D per Gear Table
- Integrated Datalogging to the 3.5” Handheld SD Card
- Free EFI Tuning Software for complete control of your Terminator X power plant
DIAGNOSTIC LED'S
- 8 Built-in multi-color diagnostic LED's allow you to quickly identify a variety of potential system issues, such as a failed TPS Autoset - faulty crank or cam sensors, or potential oxygen sensor issues!
- 1. ECU Power - Green = ON
- 2. Engine Running - Green = Running - Yellow = No RPM
- 3. Wideband Status - Blue = Too Hot, Too Cold, Slow Warmup, or Uncalibrated, Green = OK!, Red = Sensor Failure, Yellow = Sensor Heating, Off = Sensor Disabled.
- 4. TPS Calibration - Green - Calibrated, Red = Calibration Error, Cyan = DBW Pedal Calibration Error, Purple = DBW TB Calibration Error.
- 5. Undefined - Future Use!
- 6. Crank Signal - Green = Tooth Detected, below crank to run RPM (400RPM), Blue = Gap Detected, below crank to run RPM (400RPM), Red = Crank Error Detected, Off - Synced Properly.
- 7. Cam Signal - Green = Tooth Detected, below crank to run RPM (400RPM), Blue = Gap Detected, below crank to run RPM (400RPM), Red = Cam Error Detected, Off - Synced Properly.
8. Undefined - Future Use!

IDF and IDA pattern throttle bodies, with a DIFFERENCE!

What makes the throttle bodies we use so different? We use the best throttle bodies we could find, Jenvey!
When it came to throttle bodies, we went with the best. The best looking, and the best fitting/clearing! Jenvey throttle bodies place the injector inside between the barrels! This means no fuel rails to fit in the engine bay, nothing to bump and start leaking, etc. These throttle bodies fit in the engine bay exactly the same as a set of Weber IDA's or IDF's! Built in Throttle Position Sensor, and extensions on the injectors! Keep that old school look in your engine bay, with the performance of EFI!
Everything you need, in one package!
We've assembled everything you need to install EFI onto your engine. Electronics, throttle bodies, intakes, air filters, linkage, idle control valve, fuel system, etc. We modify the Holley harness for VW's, for a simple plug and play system. The only wires you need to connect that don't plug right in, are a two negative battery terminals, two positive battery terminals, negative coil (or tach output depending on your system), key-on ignition power, and the output for the fuel pump that is already wired with a relay ready to go! Since these are built to order, we can also modify the harness and EFI tune as needed, for example we can add what's needed for crank trigger ignition for a full ignition map controlled onboard by the ECU, etc! We load three different tunes into the color touchscreen handheld for you to pick which idle air mixture works best for your application (12.5:1, 13.5:1, and 14.5:1). After that, it's a matter of driving it around! The idle air control valve, once adjusted with the carburetor sync, will help maintain a target idle speed for your engine. Higher when cold, normal when up to operating temp, and a bit higher again when temps are high (hot summer day getting off the freeway) to help aid in cooling and keep the oil light out at idle. It is really the most user friendly EFI system we've found and have years of Holley Sniper (virtually same software) experience to back up our tunes and knowledge!
