Suzuki Servo Buddy 42-1112

The Servo Buddy is THE solution to the common problem of what to do about the factory exhaust valve and servo motor system.

Completely eliminating the servo motor, valve, cables, etc. not only drops weight and frees up valuable space, but utilizing the Servo Buddy improves reliability by eliminating the common FI codes and faults of the factory servo motor.

The Servo Buddy is a must have when switching to an aftermarket exhaust, and even works great with the factory system.

The Servo Buddy®, by SkutrNet, is a small electronic device that replaces the servo motor. By interfacing directly with the engine control unit the servobuddy can emulate a fully functional, stock, exhaust valve and motor system. By doing so the ECU has no idea anything is different from stock and will happily operate as intended without any FI lights or faults being triggered. This is important because if you have retuned your motor it ensures the correct fuel maps are being used and the bike does not go into any sort of “limp home mode”.

The factory motor unit really contains two components inside, the motor that spins the pulley, and a sensor that reports the motor position. The fuel injection system detects faults by monitoring the sensor feedback while sending signals to the motor. When a command is sent from the ECU to spin the motor in the direction that opens the exhaust valve, the sensor is monitored to make sure it spins in the correct direction, and stops in the correct place so that it can confirm the valve is fully open. The system operates similarly when closing the exhaust valve.

The ServoBuddy uses clever electronics to monitor the servo motor control lines, and output the correct sensor feedback to the ECU. The Servo Buddy is unique as it has been intelligently designed to so exactly replicate how the real motors work that the same circuit board can be used for almost every motorcycle manufacture on the market! The differences between models come down to the wiring schemes and connectors used. Additionally, the servo buddy has been carefully designed to be safe for your precious bike with diode protection, feedback protection, ESD protection, motor and sensor side isolation and a completely hardware implemented digital algorithm to make sure it is the most reliable option available. If you don’t understand what that all means, that’s ok. It basically means we’ve designed our circuit to be as safe as possible to your bike’s sensitive electronics, and be reliable for the life of your bike. Our components are automotive or military grade for durability and long life, the connectors are made to OEM specifications, and the wiring systems are automotive quality.
