Why it matters

What the registry gives you.

01 · Trust

Client trust on first contact

Instead of long explanations — show your profile. Clients see a verified level and make decisions faster. Your status does the talking before you do.

02 · Differentiation

Stand out from the market

Most tuners have no verified status. You do. Clients, partners, and the market can see the difference — and so can search engines indexing the registry.

03 · Progression

Clear progression path

The registry tracks your progress. Every course raises your rating. You always know where you stand and what comes next — measurable, public, undeniable.

Recognition

Two forms of recognition.

Every completed course is recorded. Every level reached is recognized. One digital, one physical — both verifiable.

Course Certificate

Digital certificate

Issued for every completed course. Records a specific skill — verifiable from your CertifiedTuners.com profile.

  • Available for download and print from your profile
  • Linked to your CertifiedTuners.com profile
  • Added automatically after course completion

You don’t receive a document. You receive membership in the guild.

The rating

From ⭐1.0 to ⭐5.0.

Status = who you are.
Rating = your progress toward the next level.

1.0

Foundation

ECU fundamentals, safe read/write, working with existing calibrations.

2.0

Tuning Engineer

You create your own calibrations — not copying, building.

3.0

Reverse Engineer

Working with ECU logic and firmware structure (Ghidra).

4.0

ECU Expert

Complex cases, non-standard solutions, deep expertise.

5.0

Instructor

Teaching others, shaping the industry.

How to read the rating
2.6

Already a Tuning Engineer. Strong practice. Not yet a Reverse Engineer.

3.9

Almost ECU Expert. One step away from deep expertise.

The process

How to get listed.

Three steps. The application takes 3 to 5 minutes. The recognition lasts your whole career.

01

Complete a course

Finish a Tuners Guild course and earn your digital certificate. This is your proof of competence — the prerequisite for the registry.

02

Fill out the application

Takes 3–5 minutes. Fill in English — this is an international registry. Your responses go through a review process before publication.

03

Your profile goes live

After review, your profile appears on CertifiedTuners.com — verifiable by your clients, indexed by search engines, recognized internationally.

You can order your Certified Tuner Kit separately after being added to the registry. Both forms work independently — registry first, kit when you’re ready.

Apply

Two forms. One registry.

Start with the registry application. Order your branded kit later — once you’re listed.

International Registry

Join CertifiedTuners.com

The end of guessing

Other tuners guess what level they’re at.
You know.

Verifiable status. International registry. Branded recognition. Three things that turn “I’m a chiptuner” into “I’m certified at ⭐3.4.”
