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 boats 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 boats is controlled by the Electronic Engine Management, also referred to as ECU, or ECM. Smart-Tune-X Suzuki DF60A fuel tuner spoofs engine sensor signals being read by the Engine management, resulting in an adjustment to the fuel trim settings which causes the increase in power as well as improves speeding up and throttle sensitivity through the revolution range.Suzuki DF60A Smart-Tune-X features new unsurpassed options that allow this remapping chip to far outperform other boat tuners. The ECU chip works to optimize the fuel curve settings for maximum power output and extra throttle response. With Smart-Tune-X Suzuki DF60A fuel controller, your fuel programming get an extensive recalibration that delivers pony and torque you will notice instantly. It also incorporates the outstanding In-built Auto Temp Compensation (ATC) system. 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 on high-power marine engines. Smart-Tune-X Suzuki DF60A 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.
