We are happy to introduce to all Yamaha 998 Turbo powered snowmobiles Closed Loop Fuel Control

This engine ECU was designed to run on an open loop configuration. In turn, environmental conditions (temperature, humidity…) affect the air/fuel mixture even with a proper tune;
-Hot ambient temperature enriches the fuel mixture (more fuel)
-Cold ambient temperature leans it (less fuel)

The solution
Adding a proper O2 sensor and closed loop algorithm allows the engine ECU to read the air/fuel mixture and adjust it to compensate for the current environmental conditions.
The closed loop air/fuel ratio has targets for both cruising and full throttle situations. Cruising AFR target is leaner to provide better fuel economy while a richer target is used at high or full throttle for maximum power.

Results
-Proper power delivery under hot conditions by preventing the air/fuel mixture from being too rich
-Proper fuelling when it’s very cold
-Automatic compensation relatives the sled intake and exhaust paths configurations
-Maximum engine power delivery in all environmental conditions at high or full throttle
-Better fuel economy while cruising at low or mid throttle. Up to 20% less fuel consumption*.

*Results will vary depending on driving style, environmental conditions and other factors.
Usage of the Turbor Performance AEM Wideband O2 module (pre-wired and plug in) is required.
Failsafe protections have been implemented in the event of a sensor issue.

We have been testing the close loop for more than 2 years now with great success! Close Loop will be available as an upgrade to all existing and up-coming Turbor Performance reflashes very shortly.
