Most tuners stay in tier 1. All the money is in tier 3.
90% of ECU tuners stay where 10% of the money lives. We teach the methodology that moves you up — four tracks from combustion physics to firmware reverse engineering, taught by Thomas Pirowski.
Three things that make our courses different.
Methodology, not templates
You learn the physics behind every map change. When you understand why a calibration works, you can solve problems you have never seen before. Letters first — then any book.
Fundamental → Practice → Mastery
Each track follows the same progression. Theory first, then real ECU files, then advanced cases with direct instructor support. Build skill in the order it actually compounds.
Built by practitioners, not academics
Every course is created by engineers who calibrate ECUs daily. Not theorists, not resellers — working professionals who teach what they actually do.
Direct access to Thomas
Closed student forum by level. Real names, real questions, real answers. You’re never stuck alone with a file you don’t understand.
Four tracks. One destination.
Whether you’re starting from zero or already calibrating — there’s a clear entry point.
ECU Foundations
Your first step into ECU calibration. Learn to read and write ECU safely, master WinOLS, and understand firmware structure — before you touch a single map.
From €570
Learn more →Diesel
Engine
Engineer your own diesel calibrations — Stage 1, DPF/EGR, AdBlue — without buying files from other calibrators. Built on physics, not guesswork.
From €970
Learn more →Gasoline Engine
Tune any gasoline engine — turbo or NA — with calibrations you can defend on the dyno. Ignition, load models, AFR, torque management.
From €940
Learn more →Reverse Engineering
Read firmware for any ECU — Bosch, Hitachi, Continental — across three architectures (TriCore, Renesas, PowerPC). No DAMOS required. Build MapSwitch, VIN protection, launch control — from scratch.
From €1680
Choose architecture →Specialist Modules. Niche markets.
Our methodology works on any platform. These 1:1 masterclasses open niche markets with almost zero competition.

Lamborghini / Ferrari
Premium segment calibration. One tune for a client = €2000–€5000. The course pays for itself in 1–2 clients. Pure margin after.
BRP SeaDoo / SkiDoo
Marine and recreational vehicle tuning. One tune for a client = €500–€1500. The course pays for itself in 3–7 clients. A niche market where almost nobody else teaches the calibration approach.
Kawasaki / Yamaha
Renesas architecture — a different world from Bosch. One tune for a client = €400–€1000. The course pays for itself in 4–9 clients. Expertise that doesn’t exist elsewhere on the market.
Prerequisite: Diesel or Gasoline Practice (or equivalent professional experience)

Stop buying files. Start building your own.
Every track is built on the same principle: understand the engine, then tune it. The courses give you the methodology — your work will give you the income.
