Getting Started

We recommend securing the ground cable to the negative pole on your vehicles battery. Your battery may look different from the picture.

The RJWC EFI Tuner is IP67 Rated and is Water Resistant. We recommend that you disconnect the Tuner from your machine when you wash your vehicle and avoid using a hose pipe, jet washer or pressure washer directly on the tuner.

Before starting installation, find a good location for your tuner. We recommend that you install it as high up on your bike as possible.

Make sure to clean the area with alcohol, then attach the velcro pad.

To get started, you will need to gain access to the Fuel Injectors. To do this, remove the side and front panels.

The first injector can generally be found in the circle area, tucked inside slightly.

To access the second injector, you will need to use a tool similar to a set of long reach pliers. The second injector can be found further in. 

The tuner cables are paired with colors for each injector. Either set of cables can be used for the front or rear injector, however they MUST be paired together for each injector. 

Connect the paired  cables, using the supplied zip ties, route the cables neatly away from any moving parts.

To find the correct settings for your model, click the text below for your model.

All our tunes are dyno tested and AFR tested, but different countries have different fuel qualities, and we recommend that you check your AFR readings. 

When ready to input the settings, open the EFI Tuner User Manual for an introduction on how to use the EFI Tuner and how to increase the Fuel Gain.
