Suits: Nissan Patrol GQ & GU and a wide range of vehicles
This unit will need to be wired into your vehicle and comes as pictured with instructions. Colour instructions can also be downloaded from Marks 4wd adaptors online.
We recommend using a GPS to check your speedometer once your speedometer correction unit has been set.
This kit MFK1000 uses the SGI-100BT Universal Signal Interface Unit & can handle nearly all of your electric speedometer signal conversion and calibration issues. The SGI-100BT can recalibrate a 2,000 pulse per mile (ppm) through 250,000ppm electronic speedometer pulse rates, either up or down. The SGI-100BT is great for adjusting aftermarket and OEM electric speedometers on vehicles after changing rear end gears, tire sizes, or drive train changes affecting the speedometer.
The SGI-100BT is used as either a signal multiplier or signal divider (25%-400%), making this unit extremely flexible for almost any application. While the SGI-100BT is intended to correct only the signal feeding the electronic speedometer, in many cases where a speed signal is shared or on a databus, the SGI-100BT can instead correct the signal feeding the engine and transmission computers. For even greater flexibility, the SGI-100BT allows multiplication up to 16x, taking an 8,000ppm signal and converting to a 128,000ppm output, and includes a regulated 5V sensor output, allowing use of the Dakota Digital SEN-01-5 speed sensor. A built-in LED display and push-button switches simplify set-up and calibration.
Note: If your vehicle is equipped with an anti-lock braking system (ABS), it is advised to ensure the signal reaching the ABS controller is not altered to eliminate any potential problems affecting control algorithms within the system. Some vehicles also utilize the output shaft speed to calculate transmission slip and lock-up. When a signal feeding the PCM is altered, this may cause the PCM to detect a constant slip. Consulting a service manual may be of assistance in determining the signal routing within the vehicle if the SGI-5 is decided to be used in a situation such as this.
Unit measures 4" x 2" x 1" and is designed to be mounted inside a vehicle.
Note: If your speedometer is not perfectly accurate though the entire range, our unit cannot fix this.
Note: If your vehicle is a 2012 model or newer please check if it has a speed sensor located on the transfer case - if it does have the sensor this unit will work in your vehicle
