Esse Werks ENET Cable — OBD to Ethernet for bootmod3

$25.00

OBD-II 16-pin to RJ45 ENET (Ethernet) cable for bootmod3 flashing, datalogging, and coding. One end plugs into the car's 16-pin OBD-II port; the other into a laptop's Ethernet port (or a USB-to-Ethernet adapter). Required hardware for every BM3 license seat — without it, you can't flash a calibration to the ECU.

What this is

A purpose-built OBD-II to Ethernet (RJ45) cable carrying the BMW ENET protocol that bootmod3 (and BMW's own ISTA diagnostic software) uses to communicate with the ECU at flash speed. Esse Werks branded, sourced from a reliable supplier.

Compatibility

  • BMW chassis with the standard 16-pin OBD-II port and ENET-over-OBD support (F-series and G-series across the lineup, plus late-production E-series with OBD-Ethernet support)
  • All MINI F-series
  • Works with bootmod3 (PTF) flashing software on Mac and PC
  • Works with BMW ISTA diagnostic software
  • Works with E-Sys coding software

What's in the box

  • One Esse Werks ENET / OBD-Ethernet cable (approximately 6 feet — long enough to reach from the OBD-II port to a laptop on the driver's seat)
  • Esse Werks branded sleeve

What you also need

A laptop with an Ethernet port (or a USB-to-Ethernet adapter — Apple's USB-C to Ethernet adapter works with this cable on Mac, similar adapters work on PC). The bootmod3 software is downloaded separately from PTF Tuning at protuningfreaks.com. Your BM3 license seat is purchased through PTF or via our calibration order intake.

WHY WE BUILT ESSE WERKS
We started Esse Werks because the cars we cared about were stuck between two bad options - a dealer that treated any modification as a problem, and a parts catalog that sold you a box and wished you luck. We wanted a shop that logs the car, builds the calibration to match, and stands behind the result the way an engineer stands behind a number. That gap is the whole reason we exist, and it is why every part we ship and every tune we write has to earn its place on the car. When you buy from us, you are buying the shop's judgment, not just the part in the box.
