Why Fit a Throttle Controller to Your Haval H9?

The Haval H9 uses electronic (drive-by-wire) throttle control, which builds a factory-programmed delay into the time between pressing the accelerator and the engine responding. This throttle lag is most noticeable when pulling away, merging, overtaking, towing or driving off-road.

The Roar 4X4 Throttle Controller remaps the pedal signal so your engine's existing power arrives sooner. It does not add horsepower or torque; it removes the delay. Sport and Race modes give sharper response for touring, towing and off-road driving, while Economy mode softens delivery for relaxed highway driving.

Frequently Asked Questions — Haval H9 Throttle Controller

How do I know plug type 151 is correct for my H9?

The factory fitment list shows plug type 151 for the Haval H9 (2014 onwards), all engines. Always compare your pedal connector with the plug picture above before installing. If you're unsure, contact our team with a photo of your plug.

Does it increase power or just throttle response?

It changes how quickly your H9's existing power is delivered. It does not increase horsepower or torque; it removes the factory throttle delay so you feel the power sooner.

Can I use it while towing with my H9?

Yes. Many owners use Sport or Race mode while towing for better response when merging, overtaking or climbing hills, and Economy mode on long touring legs.

Is it compatible with aftermarket ECU tunes or chips?

Yes. The throttle controller works independently of ECU tunes, performance chips and exhaust upgrades.

What does Anti-Theft Mode do?

Anti-Theft Mode greatly reduces throttle input, making the vehicle very difficult to drive and adding a layer of security against unauthorised use.
