A law.racing project for TurboLamik 8HP transmissions

LR TCU is engineered by law.racing: functional, high-precision software focused on the TurboLamik ZF 8HP TCU. The goal is simple. Give people running an 8HP a proper tool for calibration and datalogging, and a clear guide for wiring, so a swap is something you can actually understand rather than guess your way through.

What it is

A full calibration editor and live datalogger for the TurboLamik TCU. Open your .bin, see every table as a heatmap, edit and share. The desktop app adds the live hardware side: connect to the TCU over USB, read, write and verify the tune byte-for-byte, watch live gauges, and replay a datalog directly over the map. Alongside it there's a plain-English guide to every table, the pinout, ECU CAN integration and troubleshooting.

Why we built it

The 8HP is a brilliant gearbox and the TurboLamik controller makes it usable behind almost any engine. The tuning side, though, ships with hundreds of tables and very little explanation. We wanted the tool we wished existed: everything documented, every value editable, and the dangerous corners clearly marked, so the hard-won knowledge lives somewhere you can search instead of scattered across forum threads.

Independent, and honest about it

This is an independent software project by law.racing. TurboLamik makes the hardware and official firmwares; we make this software and the guide. LR TCU is not affiliated with, or endorsed by, TurboLamik. The definitions and notes are well-researched work from people who tune these, not gospel from the factory, so always verify before you flash.
