This guide provides a straightforward walkthrough for installing a Burger Tuning JB4 on an Audi RS3 8V FL. While Burger Tuning is developing a comprehensive guide, this aims to bridge the gap and get you started. The process is surprisingly easy, focusing on connecting the JB4 to your car’s OBD2 port and splicing two existing engine connections.
Locating the Firewall Grommet and OBD2 Connection
The first step involves running the JB4’s OBD2 connector wire through the firewall. On the driver’s side, locate the grommet above the dead pedal. You’ll need to create a small hole in this grommet to feed the wire through. Using a ballpoint pen is recommended for this task to avoid damaging existing wires.
From the engine bay, locate the pen, likely near the positive jump terminal. Once found, feed the OBD2 connector wire from inside the cabin through the hole you created.
Connecting the JB4 to Engine Connectors
Next, remove the engine cover to access the necessary connectors. You’ll be working with two specific connectors, easily identifiable with the photos provided.
The first connector is near the intake filter box. Disconnect it and splice in the purple wire from the JB4 harness.
The second connector is located towards the top of the engine. Disconnect this connector and splice in the multi-colored wire from the JB4 harness (not the green one). The connectors are keyed, so you can’t connect them incorrectly.
Finalizing the JB4 OBD2 Install
After making the connections, neatly route the wires and plug the OBD2 connector into the JB4 unit. Secure any loose wires with zip ties, ensuring they don’t interfere with any moving engine parts. Replace the engine cover.
Your JB4 installation is now complete. You may experience a traction control or check engine light initially, or the car might not immediately reach full boost. This is usually temporary. Consult Burger Tuning’s documentation for specific map settings and troubleshooting. This simple Jb4 Obd2 Install process allows for significant performance enhancements to your Audi RS3.
