Improve Throttle Response. Eliminate your 4Runner's sluggish throttle response with a C&L Throttle Controller. All modern vehicles use a drive-by-wire system that controls the throttle body electronically, similar to a dimmer switch. While innovative, this design causes an irritating delay that is most noticeable when trying to speed up to merge with fast moving traffic or when passing a slower moving car. The C&L Throttle Controller actually boost this signal to eliminate the delay for quicker, snappier throttle response, making it a must have for all drive-by-wire vehicles. Eight Modes. The C&L Throttle Controller comes with (8) preset control modes for Comfort, Sport, Race, ECO, Normal, Anti-Skid, Intelligent, and Anti-Theft applications. Each mode can further be adjusted with nine levels of sensitivity. This allows you to select the mode that works the best for your own personal driving style and needs.

·H1 - Comfort. Balances performance and fuel economy.

·H2 - Sport. Improves engine response for better performance during daily commuting.

·H3 - Race. Maximum performance with immediate throttle response.

·EC - Fuel-Efficient. Designed for fuel economy.

·NOR - Normal. Acceleration is set to factory defaults.

·SNO - Anti-Skid. Suitable for slippery conditions. Reduces tire spin by delaying the throttle response at initial acceleration.

·OOO - Intelligent. Matches the acceleration automatically according to normal driving habits.

·LOC - Anti-Theft. Throttle pedal will have no response.

Easy Plug & Play Installation. The C&L Throttle Controller connects directly into the stock throttle position sensor found on the drive-by-wire gas pedal using an OEM style plug and play connector with no permanent modifications required. The Throttle Controller is 100% reversible and will not leave residual codes on the factory PCM making it warranty friendly.
