text: Audi RS7 Wideband Electronic Fuel Injection Enhancer MAGNUM O2 Sensor EFIE Adjuster 5-Wire Wideband
  The Magnum Wideband Electronic Fuel Injection Enhancer was developed to modify the exhaust air fuel sensor signal in the H2O converted engines. After installing an H2O cell, more fuel needs to be processed to achieve extreme engine fuel economy cranks up. After we inject H2O gas into the engine, the exhaust gas oxygen sensor reports a change in the consistency of the exhaust gas to the Engine computer, and accordingly the Electronic Control Module tries to compensate the missing fuel by enriching the mix. The lean fuel report will also indicate an MIL code, tripping the MIL light and then initiating the Electronic Control Unit limp mode. The Powertrain Control Module limp mode can dramatically ruin engine economy gains delivered by your H2O system. Wideband Electronic Oxygen Sensor Enhancer is not intended to be a fuel saver by itself, but can warrant a notable improvement if your Audi RS7 runs on Water4gas. In the case of a repetitive service light issue, an oxygen sensor simulator is required on OBD-II vehicles fitted with a multi-exhaust air fuel sensor system. Since the Air Fuel Ratio in up-to-date EFI vehicles are controlled by the ECMs and most factory Power Control Modules are set to maintain a 14.7:1 air/fuel ratio, known as a stoichiometric fuel mixture, you are unable to trim manually or mechanically as you would on carbureted engines. Too much oxygen will make the Power Control Module think that the mixture is too lean. And due to the lean fuel signal, the Powertrain Control Module delivers more gas, and vice versa, if less O2 is sensed, the PCM thinks the mixture is too rich and it will inject less gas to the engine. If you install a HHO generator, then the O2 content in the exhaust will significantly rise. The more powerful water4gas system you buy, the more oxygen will travel in the exhaust gas along with the hydrogen, and this will result in a fuel lean signal. As opposed to your original goals, the Electronic Engine Management will send more fuel to the chambers. We need to overwrite the Electronic Control Module into thinking that the engine is still burning efficiently by fooling the Electronic Engine Management into sensing that there is less O2 in the exhaust than there actually is. Modification of the amount of voltage signal needed to accommodate the different amounts of hydrogen being led to your Audi RS7 engine is simply adjustable through the Magnum EFIE O2 Sensor Adjuster. The Magnum Wideband EFIE Oxygen Sensor Enhancer will modify the exhaust o2 sensor signal in a range of 0 up to 50%, delivering the Powertrain Control Module a fluctuating fuel rich signal. As a result, the Electronic Control Unit will enrich the air to fuel mixture and you can effectively control the amount of standard fuel in order to obtain the big gains in economy.
  The Magnum adjustable Audi RS7 Wideband Electronic O2 Sensor Enhancer wires inline between the exhaust gas oxygen sensor and the Power Control Module. The EFIE Oxygen Sensor Enhancer maximizes the Air Fuel Ratio by mimicking a fuel rich status. While you are injecting H2O gas into the engine, you need to lean the air/fuel mixture if you really want to save gas, otherwise the engine will run on an air/fuel blend of HHO that has too much standard fuel, ruining the engine HP and failing the engine economy enhancement. As a rule of thumb, when you are driving on HHO, you have to feed the engine less regular fuel.
  This Wideband EFIE O2 Sensor Enhancer works on your Audi RS7 if it is fitted with 5- or 6-wire air fuel sensor(s). This HHO chip will not work on titania or 1 up to 4-wire narrowband oxygen sensors.
  Please check the sensor type prior to purchase or feel free to contact our Tech Team . The Magnum Wideband EFIE will help you get out of the closed loop - safe mode on your Audi RS7 by tricking the oxygen sensor signal to the Powertrain Control Module, thus allowing the correct adjustments for various driving conditions to be made. Basically the exhaust gas oxygen sensor informs the ECU on its O2 readings, delivering the Engine computer a fluctuating voltage between 0…1 Volts on narrowband sensors and 0…3 Volts or 0…5 Volts on wideband oxygen sensors. In order to adjust to a higher voltage that refers to a rich mix, the Electronic O2 Sensor Enhancer adds an adjustable voltage to the lambda probe voltage. This extra voltage compensates the variations caused by Water4gas. Adjustments to the trim screw can change the EFIE's voltage correction by 1 mV. This fine tuning will allow you to reach peak MPG and result incredible economy. The Wideband HHO Oxygen Sensor Adjuster is a component of an HHO cell. Magnum Tuning bears responsibility for the functionality, the appropriateness of the cycle of the fluctuating o2 sensor signal and the voltage adjustment but we don't take responsibility for any fuel mileage gain realized or not realized on your Audi RS7. Please be aware, we take responsibility for the appropriate voltage adjustment and the compatibility but do not warrant for fuel saving gains which depend on the overall setup of the particular water4gas system and the adjustments committed by either this EFIE or other enhancers, the volume of hydrogen produced by the water4gas cell, and the electronic pulse modulation of HHO cell. According to the sensitivity of the particular Electronic Control Module, a MAP/MAF sensor adjuster might also be required in conjunction with the EFIE oxygen sensor enhancer.
