Linear Magnetic Magic.

A Throttle Position Sensor or TPS system provides information to the ECU for a variety of purposes including:

  • 3D ignition mapping in Yamaha YZ250 and other Japanese 2-stroke dirt bikes
  • Variable oiling rate in Beta 2-stroke dirt bikes equipped with oil injection systems
  • Real-time ignition modulation in aftermarket ECUs like the PowerCDI

SmartCarb’s proprietary MagVolt™ TPS comprises a linear-magnetic position sensor and a magnet mounted in the throttle slide. The sensor reads throttle position through the wall of the carburetor and relays information to the ECU. Unlike conventional piezoelectric resistance type sensors requiring additional moving parts and calibration, MagVolt™ TPS bolts onto any 36-40mm SC2 model SmartCarb, uses no moving parts, and creates no potential for air leaks.

Note: There is no need to purchase this product with a new 36-40mm SC2 model SmartCarb. If ordering a new SC2 for your TPS-equipped application, simply select the TPS option when purchasing and we will provide the correct connector style for you.
