S85 Injector Calibration File-S65 Injector Swap

E6x M5/M6 Injector Calibration File (For S65 Injector Swap)

If you’re running S65 injectors on your S85, this calibration file is essential. The stock S85 injectors are either unavailable or priced at over $240 each, making them an unrealistic option for most. Most enthusiasts are now switching to S65 injectors — but the DME requires proper injector data for the swap to work correctly.

This file provides the correct injector coefficients, allowing your S85 to run smoothly and reliably with S65 injectors. 

What This File Does:

This calibration provides the correct injector coefficients needed to run S65 injectors on your S85 — ensuring proper fueling across all conditions.

✔️ Smooth, clean idle
✔️ Stable cold starts
✔️ Accurate part-throttle fueling
✔️ Full compatibility with stock or tuned cars

Installation Instructions:

1. You will need a K+DCAN cable with EDIABASLib firmware flashed (such as BimmerGeeks).
   If you don’t already have one, we highly recommend picking one up — it’s a must-have tool for any S85 owner.
2. Send us a full read of your car’s current file.
   (We’ll guide you through it if you need help.)
3. Within 24 hours, we’ll send you back a modified version with the solutions you chose applied — ready to flash and drive.
