Gasoline Mastery.
Engineering Stage 2 and Stage 3 builds.
Advanced recorded sessions for tuners already shipping Stage 1. Software adaptation for modified intake, turbocharger, injectors, head work. Knock-margin engineering, MAF/MAP correlation, torque models built from physics, not pattern-matching.
Prerequisite · Gasoline Practice or equivalent · Recorded format
Six advanced topics. From rules to engineering models.
Mastery covers the work that separates calibrators from calculator-clickers. Stage 2 and Stage 3 gasoline builds with mechanical modifications — where Stage 1 frameworks stop working and physics models take over.
Stage 2 calibration framework
Beyond the Stage 1 ceiling. Software adaptation when the engine has new injectors, larger turbo, downpipe/intake hardware — the changes that break Stage 1 fuel and ignition assumptions.
Stage 3 calibration framework
Full-build territory. Internal engine work, head porting, cams, turbocharger upgrade. The ignition and fuel maps you can’t approach without engineering math — and the math itself.
Knock-margin engineering
How to read knock activity in calibration, set ignition timing against detonation limits across load-RPM space, and build margin headroom for octane variance, intake-air temperature, and ethanol blends.
MAF / MAP correlation under modified airflow
MAF rescaling for larger MAF housings, MAP-only fallback logic for turbocharger upgrades, the air-charge model recalibration that prevents lean spikes when the airflow path changes.
Engineering calculators
You build your own injector duration calculator, AFR target calculator, boost-pressure-to-torque model. Not templates — actual computational tools you keep and reuse for every future client.
Computational map building
How to build a fuel, ignition, or torque map from physics models when you don’t have a working reference file. The skill that separates calibrators who own their work from those who depend on someone else’s tune.
The shift
From rules to models.
Stage 1 has a framework: torque, fuel, ignition, air — apply the recipe, validate on dyno. Stage 2 and Stage 3 are different. Larger turbos, different cams, new injectors break the framework. You can’t pattern-match against the OEM file; you have to calculate. Mastery teaches the engineering math that lets you build a gasoline calibration when no reference file exists.
Everything to handle a Stage 3 gasoline build with confidence.
- Recorded video lessons on Stage 2 and Stage 3 gasoline calibration — self-paced, lifetime access, no scheduling pressure.
- Engineering calculators you build in the course — injector duration, AFR target, knock-margin, boost-to-torque model. Reusable on every future project.
- Computational map-building methodology — the technique for building fuel, ignition, and torque maps from physics models when no reference file exists.
- Real ECU case studies on Bosch MED17 / MED9 / MG1, Continental SID/EMS, Denso, Hitachi — the gasoline platforms you’ll see in production.
- Scrambler tool access — 50 protected files per month, continued from Practice tier. Bundles your Stage 2/3 calibrations the same way you’d protect Stage 1 work.
- Certificate on completion — verified on certifiedtuners.com with Mastery-tier credential.
- Monthly Q&A with Thomas — bring your edge cases to the working engineer who built the course.
- Course updates included — as new ECU platforms come into focus or methodology refines, your access updates with it.

Thomas Pirowski
6 years at Volkswagen Racing as software engineer. First to develop DPF-off solutions and crack ECU checksum on Trionic8, BMW EDC17, Tesla, Volvo. Mastery covers the methods Thomas developed across 30 years of gasoline and diesel calibration work.
Full instructor bio on Gasoline track →When intuitive tuning ends, this is what starts.
Eight years in chip tuning. I’d been practicing in WinOLS on my own, building what I thought were solid calibrations. After the course I realized I was doing almost everything wrong — not the keystrokes, the reasoning. The course taught me to think, not just blindly execute steps.
I systematized fragmented knowledge and moved to a qualitatively new level. Now I don’t just replace sensors and read errors — I analyze data, understand the controller’s logic, and can perform fine-tuning. One of the most valuable learning processes in my career — for anyone who wants to stop being a button-pusher and become a real engineer.
Before you enroll
Is Mastery recorded or live 1:1 with Thomas?
Recorded. As of 2026-05-14, Mastery switched from 1:1 sessions to a recorded videocourse format. You watch at your own pace, lifetime access, no scheduling required. Q&A access with Thomas continues through the monthly community sessions.
Do I need Gasoline Practice before Mastery?
Yes. Mastery assumes you’ve shipped Stage 1 calibrations on real gasoline ECU files and understand the Practice framework. If you haven’t taken Practice, the Complete bundle (F+P+M) costs €3,450 — saves €1,170 vs separate enrollment.
What ECU platforms does Mastery cover?
The engineering methodology applies to all common gasoline ECUs — Bosch MED17, MED9, MG1, Continental SID/EMS, Denso, Hitachi. The Stage 2/3 workflows, knock-margin engineering, and computational map-building transfer universally across direct-injection and port-injection platforms. Lesson examples are platform-specific where it matters for the technique.
What’s the refund policy?
14-day refund window from purchase, provided less than 30% of the lessons have been opened. The recorded format makes refunds clean — no scheduled time to recover. Get in touch within the window.
How long does Mastery take?
About 2 months at ~1 hour per day. Mastery topics are denser than Fundamental or Practice — Stage 2/3 calibration involves more variables and more verification work. Self-paced with lifetime access. Most students return to Mastery chapters as edge cases come up in their work — it’s a reference, not a one-pass course.
Mastery costs less as part of Complete.
Fundamental + Practice + Mastery together saves €1,170 vs separate. If you don’t have Practice yet, Complete is the obvious math.
Build the calibration. Don’t copy it.
Stage 2 and Stage 3 are where pattern-matching ends. Mastery is where engineering math begins.
