FJO Wideband Air/Fuel Ratio Analysis System |
When you're building performance , proper tuning is critical for maximum reliable power and torque. Formerly, EGT (Exhaust Gas Temp) gauges, narrow band O2 sensors, and spark plug reading were the only means to get information about what AFR (Air Fuel Ratio) the engine was actually running.
Thankfully today no one needs to rely on any of these primitive and inaccurate methods. With the development of wideband oxygen sensors and modern electronics it is now possible to accurately measure AFRs over a wide range from very lean (20:1) to very rich (10:1) in just a fraction of a second - consistently and reliably.
Features & Benefits
Choose this one if you just want to drive a gauge or if you need to provide AFR readings to an ECU or datalogger. Includes mini wideband AFR controller (single channel), wiring harness, and oxygen sensor bung and plug. Dual analog outputs provide "FJO legacy" and 0.5-4.5 volt linear output curves. Order SO20003 or SO20004 sensors, sensor cables and other options separately.
Choose this one if you want to datalog and analyze your AFR on your laptop. Includes mini wideband AFR controller (single channel, with RPM input), wiring harness, oxygen sensor bung and plug, a PC serial cable, and software CD. Dual analog outputs provide "FJO legacy" and user configurable output curves. Order SO20003 or SO20004 sensors, sensor cables and other options separately.
Choose this sensor if you plan on running any racing gas at all. In general wideband oxygen sensors tend to fail in the presence of racing gasoline, but we've run this sensor with nothing but racing gas and it has lived for several racing seasons. More expensive, but these will last.
Choose this sensor only if you will never be running it in the presence of racing gas. Must less expensive than the NTK version, but it will die almost immediately if you run it in racing fuel. If you don't run any racing fuel then this is the sensor for you.
Round 3-digit LED display with a 40 led dot bar graph sweep. Ultrabright LEDs for daytime visibility.
The Bosch sensor has roughly an 18 inch (.5 meter) pigtail. The NTK sensor has only about 6 inches of pigtail (15 cm.) If you need to mount your controller further away from the sensor then you will need one of these extension cables. All sensors from FJO have their own custom connector, so these cables will fit either of NTK or Bosch sensor from FJO (but not those available elsewhere. Available in the following lengths:
A 6 foot long cable harness which directly connects the WBAFR controller to supported products such as the FJO Water Injectino System or the Progressive Nitrous Mini-Controller.

FJO Water Injection System |
The use of water and methanol to control detonation in high compression or boosted engines is a time-proven technology. This advanced product is engineered to deliver a fine mist that can be precisely metered based on MAP PSI, TPS, RPM, and Fuel injector duty-cycle. With the use of 1 and 2 dimensional maps, it is possible to program the controller to deliver exactly the correct amount of spray without the risk of flooding the combustion hamber. Their unique nozzle-solenoid design allows for instant control and delivers a mist so fine that complete evaporation is almost instantaneous. This results in a more effective use of the spray without risk of condensation in the intake. The FJO Water Injection system is constructed using materials which are engineered for and unaffected by water and methanol. To avoid compromising the performance of the system, materials such as brass, raw or anodized aluminum, raw or plated steel, natural rubber, and silicone should not be used as they are not suitable for use with water and/or methanol.
Built to the same rugged specifications as all of FJO's products, this system sets a new standard in water injection.

FJO Progressive Nitrous Mini-Controllers |
The Progressive Nitrous Mini-Controller combines the functions of their 2-STAGE TPS AND RPM WINDOW SWITCH and their HIGH CURRENT SOLENOID DRIVER all into one very compact module. It can progressively drive two channels, each with a 40 amp load capacity (continuous duty). The device also supports low-voltage OEM, V10 or 3 cylinder TACH signals without the need for additional adapters. It works with most OEM throttle position sensors including most drive-by-wire vehicles. This device also includes FJO's "real curve" ramp which allows you to create a progressive curve instead of just a ramp, and the ramp can be either time based or RPM based. All this and only the size of a spark plug box.
The Progressive Nitrous Mini-Controller 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 degrees Fahrenheit (-40 to +85 degrees Celsius).

FJO Peak and Hold (Low Impedance) Injector Driver |
Finally! You have the ability to reprogram your ECU, allowing you to adjust your vehicle's air/fuel and timing curve without having to rewire the car, buy a new ECU, or lose the factory functionality provided by the stock ECU. Great! Now what happens if you need bigger high-impedance (saturation-style) injectors? Suddenly the proposition gets expensive. High flow, high-impedance injectors are far more costly than low-impedance injectors - if you can even find the right ones. And for the additional cost, what do you get? Slower response at high-RPM (resulting in a loss of fueling accuracy) and less stability at low-RPM (resulting in idling problems). When you use a PEAK&HOLD driver, low impedance injectors initially get driven with more current (called the "peak current"), which results in a stronger magnetic field to open them. More force means faster opening response. The reverse holds true when they close. Because they have a lower current holding them open (called the "hold current"), it takes less time for the magnetic field to collapse and allow the injector to close. In simple terms, a peak-and-hold driven low-impedance injector just works better. Sure, you can add a ballast resistor and use the low-impedance injectors, but in many cases this will perform WORSE than the original high impedance injector - and performance is what it's all about.
The FJO LOW IMPEDANCE INJECTOR DRIVER is NOT a ballast resistor. It actually converts the high-impedance (saturated-type) driver signal to a low-impedance (peak and hold) driver signal. This means that you get the full performance from your low-impedance injectors without needing to replace your existing ECU. The FJO LOW IMPEDANCE INJECTOR DRIVER is simple to install and is built for the demands of the racing environment.
Drives 4 PEAK&HOLD injectors with 4 amp peak and 1 amp hold currents. Kit includes cables. Designed for upgrading a factory ECU which can only drive high impedance injectors. Splicing into factory harness is required.
