Juice Boost ECU for Suzuki LT-R450 Review

Two Brothers Racing of Santa Ana, Calif. has announced the release of its new Juice Boost Engine Control Unit, which is available for the 2006-08 Suzuki LT-R450.

This simple plug in ECU bypass changes the ECU “Engine Control Unit” to a secondary engine management map designed for racing by Suzuki and hidden in your stock ECU. This install takes minutes and plugs into the stock wire harness behind the right front headlight. This secondary mapping is designed for an open exhaust and removing the airbox lid. The power increases up to 7 HP and the rev limiter goes up 500 RPM to 10,000 from 9,500. This setting works very good with the Two Brothers Racing exhaust but can be altered even more by adding the “Juice Box” which will plug inline from the ECU to the injector and add even more fuel to better match the Two Brothers Racing exhaust. You can easily add even more fuel if needed after other engine modifications are done and more fuel is necessary for optimum performance.

This Product is designed for closed course competition.

According to Two Brothers Racing, by plugging in the Juice Boost ECU bypass module, the LT-R450 will automatically be programmed to utilize a secondary racing engine map hidden inside the stock Suzuki.

“Just plug it into the stock wiring harness and feel the boost,” Two Brothers Racing says in a release.

This race mapping is designed for use with an aftermarket exhaust and modified air box, adding seven additional horsepower and boosting the rev limiter from 9,500 to 10,000 rpm. According to the company, the Juice Boost ECU is the perfect compliment to Two Brothers Racing’s LT-R450 full-raceexhaust system.

For even more power gains, the Juice Boost ECU is designed to be 100% compatible with Two Brothers Racing’s Juice Box Premium Fuel Controller. The Juice Box installs in-line between the Juice Boost and the injectors and adjusts fuel delivery with the push of a button.

“This allows you to add necessary fuel to the engine after modifications and fine-tunes delivery to maximize power gains across the board,” says Two Brothers Racing.

This Dyno compares a stock LT-R450 to one equipped two seperate Two Brothers Racing exhausts and a Juice Boost ECU.
