How It Works

At BJT.nu, we make it easy to boost the performance of your Mercury outboard with our advanced ECU tuning. Whether you want to tune remotely or send in your ECU, we have flexible options to suit your needs.


Step 1: Choose Your Tuning Option

Remote Tuning (Recommended)

With remote tuning, there’s no need to send in your ECU. You can perform the tuning yourself with a few simple steps:

  1. Requirements: All you need is a Windows PC with an internet connection and our USB Tuning Interface.
  2. Purchase the USB Interface: This tool connects your ECU to our tuning software and can be used across multiple engines. If you no longer need it after tuning, you can return it for a full refund.
  3. ECU License: You’ll need a separate ECU license for each engine you tune, ensuring optimal calibration for each setup.

Why Choose Remote Tuning? It’s fast, convenient, and lets you avoid the shipping time associated with sending in your ECU. Plus, you have the flexibility to tune other engines by purchasing additional licenses.

Send-In Tuning Option

Prefer to have us handle the tuning? You can send your ECU directly to us, and we’ll take care of the rest:

  1. Ship Your ECU: Package your ECU securely and send it to our address below.
  2. Fast Turnaround: We’ll perform the tuning and ship it back to you by the next business day.
