Working Theory Improve the performance level potential of your quad and say adios to sluggish stock fuel trim with the next generation Smart-Tune-X power control chip module. Smart-Tune is a fully adjustable fuel controller, also referred to as fuel tuner, designed for fuel injected ATV’s. It is intended to remap the lean factory fuel map settings restricted by the manufacturers. This performance tuner simply wires in-line with the signal wire of factory Air Temp sensor, which is a standalone probe or a part of the integrated Mass Air Flow sensor, and wires into the exhaust air fuel sensor harness on emission-controlled quads in order to recalibrate fuel maps for maximum performance potential. Smart-Tune-X fuel controller is designed to trick the Engine computer into thinking that the intake air is much cooler, and then the ECU will send more fuel for a richer mix. Besides this it inhibits restrictions implied by the ECU on engines, and the exhaust gas consistency is monitored by emissions-control through an exhaust oxygen sensor. It also incorporates the outstanding In-built Auto Temp Compensation (ATC) system. With this fuel controller, your fuel injection settings get an extensive recalibration that delivers HP and torque you will notice instantly. The remapping chip works to optimize the fuel injection timing for max performance potential and more throttle sensitivity. Smart-Tune-X fuel management chip overrides engine sensor signals being read by the Engine computer, resulting in an adjustment to the fuel map settings which causes the increase in power capability as well as cranks up acceleration and engine response through the rotational speed range. Smart-Tune-X features new unsurpassed options that allow this power tuner to far outperform other ATV chips. These specific ECU chips are sorted into numerous categories according to the operating range and type of IAT / MAF / MAP and oxygen (if any) sensor. Smart-Tune-X chip is available for all EFI ATV’s controlled by Engine management. Tech Training On new generation fuel injected engines you are not able to adjust the AFR in order to add more horsepower with re-jetting, like on carbureted models. Smart-Tune-X chip’s primary intent is to make this adjustment to max out the engine power. Smart-Tune-X performance chip neither affects engine reliability nor durability. This fuel tuner is designed to fool the ECU thinking the intake air much more cooler, then the ECU will send more fuel for a richer mix, besides on those engines, exhaust gas consistency is monitored by emissions-control system, through the exhaust oxygen sensor, the chip unlocks the restrictions developed by the Electronic Control Unit. These ECU chips are known to deliver unbridled horsepower to fuel injected ATV’s. Ramp up the performance potential of your quad. Some riders pay much attention to the exterior of their ATV while others prefer getting more horsepower and efficiency from the engine. The owners in general pick the second option rather than the first one. Magnum Tuning offers you an assortment of top-notch performance chips designed to optimize the engine, driveline, electronics, and other systems of the ATV. So if you are searching for stuff like that, the Smart-Tune-X performance chip is the best option. Smart-Tune-X ECU chip has been proven to be a great asset for boosting engine performance. It is unequivocally the upgrade your ATV is starving for. This fuel controller works in conjunction with your ATV’s engine management and does not affect engine reliability or durability. Worldwide popular Smart-Tune-X performance Chip can even quickly be switched on the fly, removed or re-installed at any time. Carbureted engines are not subject to being chipped hence nonexistent Electronic Engine Management referred to as ECU or ECM. On oxygen sensor models fitted with aftermarket exhaust or header, Check Engine Light (CEL, MIL, FI) is triggered until you wire up an oxygen sensor simulator in order to abolish ECU safe / limp mode. Signals fooled by Smart-Tune-X will be restored to factory by the ECU, until CEL issue is resolved completely. If top end speed is limited by factory speed governor, RPM is restricted by rev limiter, or you are about to override the factory red line RPM limit, then check out our REV Limiter. Claims correlate to factory condition engine. Defects or extensive wear and tear of related parts or systems such as oxygen sensor, sparkplug, fuel filter, injectors, injection or ignition system can result in no or minimum effect. Please get the vehicle checked by a certified mechanic prior to installation to avoid undesired inefficiency.

You don’t have to get your hands dirty installing the Smart-Tune-X tuner. Setup and adjustment doesn’t require special talent of installer. Our easy to follow, step-by-step instructions will guide you, how to install your performance chip in an hour or less, if you are lil electronically inclined. Our certified mechanics who are actively involved in racing and high performance tuning are eager to assist you. Locate the IAT (Intake Air Temperature), which is a standalone sensor or the part of the integrated MAF (Mass Air Flow)/ MAP (Manifold Absolute Pressure) sensor on the intake. Cut the IAT signal wire and contact the purple wires to the two ends. Polarity is not critical. Find the Oxygen sensor (if any) in the exhaust. Cut the downstream O2 sensor’s signal wire between the O2 sensor head and the O2 sensor plug. Connect the black wire to the wire coming out of the oxygen sensor head. Connect the blue wire to the oxygen sensor wire coming out of the ECU harness. Fix the temperature sensor with any applicable method within or at the inlet of the air filter box where air flow enters the intake. Tip: Drill a 1/4 – 6mm diameter hole in the inlet side of air filter box to drive in the sensor. Seal the hole with silicon or putty. Contact the red hot wire of the red/black dual cable to the ignition feed +12V, and ground the black to the engine frame or battery negative. Leave the black and blue wire pairs disconnected if the factory oxygen sensor is not fitted or eliminated physically or electronically. For connections crimp with bullet connectors or solder the wires in place. For soldering the O2 sensor plated wires employ muriatic acid. Never power up the tuner on constant battery feed. Please find an appropriate ignition feed DC12V on either the consumer like the radio, wiper, or fuel pump activated by the ignition key, or tap into the main fuse box. In Lambda-Boost mode (emission-controlled ATV’s with oxygen sensor only) the Dual emission control system reads constant feedback through the fluctuation voltage of the stock oxygen sensor. Smart-Tune automatically identifies the sensor type and voltage range. The in-built oxygen sensor control unit helps to override that restriction that would be implied by the factory ECU programming, as long as other sensors’ signals are being tricked. When do you use this option? In the instance of street racing, hauling, or if other upgrades require you to do so. Depending on the engine management type or performance parts preinstalled, an oxygen sensor related trouble code check engine light (CEL) might be triggered by Lambda-Boost mode. If so, test the O2 sensor to see if it works in full fluctuation range. If the O2 sensor doesn’t work in full range, it is recommended to abandon this function. Turn on the ignition key. The 499-scale LED display lights up. Crank the engine and wait until it reaches operating temperature. Start the adjustment with quarter turns clockwise. After each turn test the throttle response, power and acceleration on the fly. Conduct comparative tests like 0 up to 15 MPH, 10 up to 50 MPH or 2000 up to 5000 RPM, etc, while riding your ATV.. Settings for your specific engine unfortunately cannot be predicted. Reset and restart: Dial the knob fully counterclockwise. When Smart-Tune is unpowered or the knob is turned fully counterclockwise, the engine runs in factory mode as if the wires were not cut. In this case, factory signal readings are delivered the ECU. On Oxygen sensor models if the exhaust was modified (header or free flow exhaust) and the check engine light is triggered, a Magnum oxygen sensor simulator should be wired up in conjunction with the Smart-Tune in order to remedy the ECU safe / limp mode. Claims correlate to factory condition engines. Malfunctions of either related engine component, can result in no or minimum effect. Please get the engine checked by a certified mechanic prior to installation to avoid undesired inefficiency. It is highly recommended that you perform a signal range scan on the O2 sensor (if any), the slightest defect might prevent the tuner from working efficiently.
