From diagnostician to ECU reverse engineer.
No dependency on someone else’s files.
You read fault codes but have never been inside an ECU — go to ECU Foundations.
You read and write, but hand calibration to others — go to Diesel or Gasoline.
You calibrate, but hit protection and unfamiliar ECUs — go to Reverse Engineering.
Where are you right now?
Find yourself below. That is your entry point — not where you started, but where you are today.
ECU Foundations
Your first step into ECU calibration. Read and write safely, master WinOLS®, understand firmware structure — before you touch a single map. Three formats depending on what you already know.Your step if you’re a diagnostician: you read fault codes, but have never been inside an ECU.
For technicians who need bulletproof reading and writing — no calibration yet. The foundation everything else stands on.
- Read and write ECU safely
- Checksum correction
- Boot mode & OBD interfaces
- Certificate included
If you already do safe R/W and need WinOLS, map identification, mappack building and engineering documentation — start here.
- WinOLS from Zero
- Map identification & tuning
- Funktionsrahmen & documentation
- Certificate included
Both courses together — save €420. The complete foundation: safe R/W + full WinOLS workflow. What 80% of students choose.
- Everything in Safety
- Everything in WinOLS
- Certificate included
- 14-day Graduate Pricing on L2
Diesel Engine
From combustion physics to Stage 1 calibrations. Understand why your changes work — make your own files instead of buying them.Your step if you already read and write ECUs, but hand calibration to others.
Combustion, injection strategy, boost control, torque limiters. Find any map — even without DAMOS files.
Build Stage 1 from scratch. SOI + Rail + Pre-injection = +21% power gain on real cars. Step-by-step on actual files.

Six ways to save.
No tricks.
The discount depends on your step, not on the calendar: you took the bundle, you took two tracks at once, you upgraded, you earned the certificate. No timers, no “more expensive tomorrow”, no offers that burn out.
Save 15% on two levels
Fundamental is where you learn how the ECU and its firmware work. Practice is where you solve your first tasks on real files. Paid jobs start after Practice. Essentials is both courses in one purchase, 15% cheaper than buying them one by one. You save €320–€560, depending on the track.
Save 25% on a whole track
Complete is the whole track in one purchase: Fundamental, Practice and Mastery, 25% cheaper. Mastery is the top level. It teaches the jobs that few tuners can do, and these jobs pay the most. You save €1,170–€1,630, depending on the track. Best value.
Start small. Lose nothing.
Not ready to buy the whole track? Start with Fundamental. For 7 days after you pay, you can move up to Essentials or Complete and pay only the difference. Bought Essentials? You can move up to Complete the same way. The total is the same as if you had bought it all at once.
−10% on your next step
Finished a course and got your certificate? Your next purchase is 10% cheaper. It can be a new track: Diesel, Gasoline or Reverse Engineering. Or it can be the next level of the track you just finished. The discount is valid for 14 days. One certificate — one discount on one course.
−20% for lower incomes
Incomes are lower in some countries, so we lower the price there. If you live in Latin America, Eastern Europe outside the EU, Africa, South or Southeast Asia, or Turkey, you pay 20% less. We check the country of your bank card.
The discount is not added at checkout. Write to us before you pay — we check your country and send you a discount code. We go country by country, not by region.
−10% on the whole order
Buying two or more tracks? Put them in one order and the whole order is 10% cheaper — the first track too. Example: Diesel Essentials + Gasoline Essentials cost €3,357 instead of €3,730. You don’t wait for a certificate: the discount works the day you buy.
Email us the tracks you want — we’ll send one payment link. You can’t add Graduate Pricing on top.
These stack: bundle price first, then Multi-track or Graduate, then PPP. A student in Brazil who takes Diesel Complete and Reverse Engineering Complete in one order pays €6,106 instead of €8,480 — a saving of €2,374.
Not sure which track to start with — the answer is in the questions below ↓
Before you decide
Which track should I start with?
If you’re new to ECU calibration — start with ECU Foundations (all 3 courses live: Safety, WinOLS, L1 Complete). If you already read and write ECUs and use WinOLS — go straight to Diesel or Gasoline Fundamental. If you’re an experienced calibrator who wants reverse engineering — pick your architecture on the Reverse Engineering hub (TriCore, Renesas, or PowerPC). Working with Lamborghini, marine, or motorcycles? See Specialist Modules.
What’s the difference between Essentials and Complete?
Essentials (F + P, −15%) is for working professionals who need full calibration capability — Fundamental + Practice in one bundle. Complete (F + P + M, −25%) adds Mastery on top — recorded advanced calibration with deep system mastery, for tuners committed to career-level expertise. Started with Fundamental or Essentials? You have 7 days from purchase to upgrade to Complete at the bundle rate — same total cost, no penalty for starting cautiously. After that, Graduate Pricing gives you 10% off the next level for 14 days from your certificate.
Do you offer discounts for developing countries?
Yes. If you live in a country with lower incomes, you get the PPP discount and pay 20% less. It covers Latin America, Eastern Europe outside the EU, Africa, South and Southeast Asia, and Turkey — for example Brazil, Mexico, Argentina, India, Ukraine, South Africa, Nigeria and others. The discount is not added at checkout. Write to us before you pay — we check your country and the country of your bank card, then send you a discount code. We go country by country, not by region.
How long do I have access?
Lifetime access to all course materials. Watch at your own pace, revisit any lesson as many times as you need. Forum, Telegram and the Tuners Guild Discord — support doesn’t end when the course does.
How fast does the course pay for itself?
5 to 7 cars. A single custom calibration earns €200–€500. With 8 reflash requests per month — the median for our students — most recover the cost within 1 to 2 months of practice. The expensive part isn’t the course. The expensive part is the year you’ll spend trying to learn this on YouTube.
Do you teach my specific ECU?
Yes — because we teach methodology, not button-pushing. Know letters — read any book. Know the methodology — work with any ECU. One method, all cars. That’s why our students work on everything from BMW and VAG to Lamborghini, Ferrari, BRP SeaDoo and Kawasaki.
Can I learn 1:1 with Thomas?
Yes — online or at the workshop in Kraków, same price: €2,000 per day, seven hours, in English, Polish, German or Russian. Fundamental or Practice usually take from one day, Mastery from two; reverse engineering about three times longer. Bring your own ECU or project — the day is built around it. Dates are agreed in advance, usually a few weeks ahead. If you come to Kraków, travel and stay are at your own cost. Days per level ↑
What if I brick an ECU while learning?
You won’t — because we don’t teach you on client cars. Module 1 starts with reading firmware files on the bench, not flashing. By the time you touch a real ECU, you’ve already practiced read/write/checksum/recovery on virtual files. Safety methodology comes before calibration methodology. That’s why our students ship Lamborghini, Ferrari, Kawasaki and BRP back to clients running clean.
All questions answered?
Pick Your Track →A community of calibrators — with every course. For good.
This is not a separate tier. With any course you join the closed community: conversation, shared experience and mutual help — a place to ask what you didn’t get and to share what you worked out yourself. Monthly live Q&A with Thomas. Access is permanent, not just for the duration of the course.
“…the most important thing is the live interaction with other calibrators who can point you in the right direction” — Vitaliy72
Your equipment is paid for. Your clients are waiting.
The only thing between you and the next level is the skill — and now you know exactly what it costs to get there.
