Link’s CAN module allows us to plug a Bosch 4.9 wideband sensor directly into the Evolinks can port. The wideband sensor is used for closed loop operation, and data logging for tuning and for failsafe operation. On a Link ECU, the wideband is controlled directly by the ECU including the sensing element heater control. Proper heater control is critical for sensor life and poor control logic is the leading cause of sensor failure in aftermarket systems. Links OEM like O2 sensor heater control protects the sensor from thermal shock caused by start-up moisture and high-temperature operation just like an OEM ECU would.
The Bosch Motorsports LSU 4.9 wideband O2 sensor is the latest and greatest in wideband sensors. In the upgrade to 4.9 trim, the sensing element’s shrouding has been redesigned so exhaust gases can reach the sensing element faster. This reduces response time. The sensing element itself is much thinner, in fact, twice as thin so it is more responsive to the sensor heater. This also reduces the sensor’s response time. These changes to improve the sensor’s response have also made it more suspectable to thermal shock damage so accurate heater control like what Link offers is even more important than ever.
Link’s Ethanol Content Sensor is critical for flex-fuel operation. In Southern California, E85 at gas stations is still somewhat hard to find so it is important that our car be able to run on pump gas, E85 and any mix of the two. The sensor will tell the ECU the ethanol percentage in the mix. Link’s Modelled Multi-Fuel Equation makes tuning with E85, pump gas and any combination of the two easy as pie. The Modelled Multi-Fuel Equation is an extension of Link’s Modelled Fuel Equation that allows you to easily change things like injectors, fuel pressure, lambda targets at once you have tuned your VE tables. This makes tuning easier.
With Link, we will get everything we always wanted for our Evo, full control of all engine control parameters, clean OEM mimicking installation, keeping the reliable OEM wiring and connectors, and being able to cleanly add features like flex-fuel, water injection control with tuning integration, and data logging all in one.
Stay tuned while we upgrade other parts of the car to make full use of the Link ECUs capability.
