After alterations are being made to the fuel maps, oxygen sensor senses rich mix that would cause the ECU lean out the mix as opposed to our intent. Smart-Tune-X identifies the sensor type and voltage range automatically. Dual-mode oxygen sensor control system reads constant feedback through fluctuation voltage or resistance signal of stock oxygen sensor.Lambda-Boost mode (applies on emission controlled vehicles only) Smart-Tune-X is intended to conduct this adjustment to achieve maximum performance boost. On new generation fuel injected engines from the early 80's you have been unable to adjust the AFR - in order to add more horsepower to the powertrain - with rejetting, like on carbureted models.

This is known as a stoichiometric fuel mix however this is a lean mix as well because of rigorous emission standards the manufacturers have to comply with. Most factory ECU's are set to maintain a 14.7:1 air/fuel ratio.

The fuel trim on fuel injected up-to-date vehicles is controlled by the Electronic Engine Management, also referred to as ECU, or ECM. If the top end speed is limited by a factory speed governor, or you are about to trick the factory red line RPM limit, then check out our Rev Limiter.

If you can’t find the one applicable to yours, feel free to contact our Tech Support. Smart-Tune-X chip is available for all fuel injected cars controlled by Electronic Engine Management. These car specific remap 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 Nissan Maxima performance chip overrides engine sensor signals being read by the Power Control Module, resulting in an adjustment to the fuel trim which causes the increase in performance as well as ramps up speeding up and throttle sensitivity through the revolution range.Nissan Maxima Smart-Tune-X features new unsurpassed options that allow this remapping chip to far outperform other car chips. The remapper chip works to optimize the fuel trim for max horses and extra throttle response. With Smart-Tune-X Nissan Maxima fuel controller, your fuel trim get an extensive recalibration that delivers power output and torque you will notice instantly. setup doesn’t need special knowledge, you can complete a Do-it-Yourself installation as long as you are slightly mechanical and electrical minded. This Nissan Maxima performance tuner wires inline with the signal wire of the stock Intake Air Temperature sensor, which is a standalone sensor or the part of the compact Mass Air Flow (MAF, MAP, TMAP, etc.) sensor, and wires into the exhaust exhaust gas oxygen sensor harness on emission-controlled engines.

Nissan Pathfinder R52 2.Every high performance power train deserves to perform at its peak and the outstanding Smart-Tune-X controller does just that by tapping into your Nissan Maxima's engine to deliver huge performance, low-end torque and engine response gains.

Infiniti and Nissan ecu remapping supported in OBD2 Thanks to this last K-Suite update, in addition to supporting new hybrid engines, it is possible to read and write the entire contents of the ECU, including the data contained in the EEPROM, via OBD. Thanks to KESSv2, you can gain better performance, maximise the services of the vehicles and facing problems that a standard diagnosis cannot solve. KESSv2, is not only designed for cars, but can also be connected to motorcycles, trucks, tractors and boats to read and write the parameters of the engine or of the transmission. In this you can offer a complete package to your customers! But not only that, these vehicles are also supported by K-TAG. New Petrol vehicles such as Nissan Patrol Y26 V6, Nissan Qashqai, but also hybrids, like as Nissan Maxima V6 and Nissan Elgrand V6, from today are supported by KESSv2, Alientech OBD Programmer to write in a few minutes the original or modified file in the vehicle ECU through the OBD port. From today you can work via OBD on new Infiniti and Nissan models with ECU Hitachi BED431, NEC029 and NEC030, with micro SH72531, SH72533, SH72543.
