Low Impedance Injector Driver
and Siemens DEKA Injectors

FJO Racing Products is very pleased to offer a stand-alone low impedance injector driver. This product allows the use of low impedance injectors with ECUs designed for high impedance injectors only.

The LOW IMPEDANCE INJECTOR DRIVER accurately reproduces the ECU’s injector pulses in a PEAK & HOLD format and is compatible with full sequential, phase sequential, and batch fired injector pulses. There are no special set-up requirements and it installs easily between the ECU and injectors. This product can be used singly or in multiples for any number of cylinders or injector channels.

The LOW IMPEDANCE INJECTOR DRIVER is built for the racing environment to withstand heat, vibration, dirt and water. It is designed to operate over the temperature range from -40° to +185° Fahrenheit (-40° to +85° Celsius).

That's right, the best just keeps getter better--and Less Expensive!. The new KID0404 second-generation Low Impedance Injector Driver is smaller (only 4.5" x 1.25" overall), easier to install (half the wires of the old version) and has more advanced microcontroller technology that allows for never-before-seen injector accuracy and precision. All at a price that is LOWER than the first generation. For 4-Cylinder users, the FJO KID0404 Injector Driver is half the price of the nearest competitor (and, in reality, they aren't all that near to start with.) This is the one you need!

• 4 independent injector channels with input preloaded to 200 ohms
• Allows use of low impedance injectors on ECUs designed for high impedance injectors only, no need to replace OEM ECU
• Reproduces ECU injector pulses in PEAK & HOLD format (4A/1A)
• Supports full sequential, phase sequential, and batch fired injector pulses
• No special set-up required
• Can be used in multiples for 6, 8, 10, and 12 cylinder applications

• Easy to install, installs between ECU and Injectors
• Built for the racing environment to withstand heat, vibration, dirt and water
• Free direct technical support

PEAK&HOLD (low impedance) Injector Driver kit

Drives 4 PEAK&HOLD injectors, includes cables
(for upgrading factory ECU which can only drive high impedance injectors)

The Siemens DEKA I fuel injector is a fantastic low-impedance fuel injector modeled after the Bosch EV1-style injector. It has a pencil spray pattern, uses the Bosch EV1 (Minitimer) connector, and has approximately 2.35 ohms of resistance.

The body is 60mm between the top and bottom o-ring surfaces. These can generally be used in any application that can accept or be adapted to 60mm between fuel rail and injector inlet mating surfaces. If your stock injector is shorter or taller than 60mm you may need to either add a spacer or shorten the existing spacer so that a good fit is achieved.

The O-Rings that are included are sized for a hole 14mm in diameter. If your fuel rail hole or the hole where your fuel injector is inserted is either larger or smaller than 14mm you will want to get a suitably-sized o-ring to prevent leaks or o-ring damage. Here is technical drawing of the Siemens DEKA I fuel injector for your consideration:

The modified version of this injector has had the bottom o-ring retainer removed (approximately 10mm OD) so this injector can fit openings down to about 8mm in diameter. This makes it an idea fit for many different Japanese applications that used the older ND (Nippondenso) injectors, including but not limited to Mitsubishi, Mazda, and some Honda engines.

FUEL INJECTOR Sealed Connector Kit

Includes connector, pins, and seal for 18awg wire (extra pin included), fits most injectors with rectangular Bosch EV1-style connector. NOTE! Each kit includes a single injector connector. If you need injector connectors for more than one injector, order the appropriate amount. (One kit per injector.)
