Precise control over throttle actuation

An electronic throttle actuator that offers precise control over throttle actuation to help optimise induction systems has been released by Jenvey Dynamics. The device is highly modular, making it compatible with a large range of aftermarket Independent Throttle Body (ITB) kits for road or race applications.

The benefits of electronic throttle actuation include, packaging, idle control, autoblip with paddleshift transmission, launch and traction control, anti-lag, switchable pedal maps, controllable push-to-pass strategy, pit lane speed control and variable bank-to-bank control. The Jenvey electronic actuator offers the ability to closely monitor pedal position versus throttle position, improve throttle control and ensure active closure or power down to safeguard valuable competition powertrain in the event of any component failure. The device is tested to function in the temperature range of -20 to +140°C, weighs just 500g and has a maximum torque capacity of 3600Nmm, allowing throttle opening times of less than 0.1 seconds from 10% to 90% throttle.

The electronic actuator, which requires standalone ECU control, is compatible with all Jenvey ITB kits, including its downdraft SFD and SFD taper kits for the popular Chevrolet LS3 V8 engine.

“We have identified the need for a highly configurable, fit-and-forget electronic actuator that is good enough to be used in international race series, yet is more attainable than often complicated, cost- or compatibility-prohibitive bespoke fly-by-wire systems,” says Mike Jenvey, Managing Director, Jenvey Dynamics. “The Jenvey actuator is competition-proven having completed its first 24-hour race on a GT car without issue, as part of a rigorous in-house testing procedure. We believe it is a perfect solution at an ideal time for international race teams, smaller scale set-ups or even track day and performance car enthusiasts.”

“The entire design, prototyping, validation and production process of each Jenvey product is handled in-house, which gives us complete control over specification and quality,” continues Jenvey. “This means the electronic actuator is not only entirely configurable for common applications and with a range of fuelling options, but that bespoke work can be undertaken for unique or unusual applications or specific requirements for demanding race series.”
