Autotuner Tuning Tool

Autotuner is a professional-grade ECU and TCU tuning solution built for shops and independent tuners who need reliable results across a wide range of vehicles. It supports OBD, bench, and boot protocols, covers cars, light commercial, motorcycles, UTVs, agriculture, and marine applications, and comes configured as either a Master or Slave unit depending on your operation. One tool. No locked features. No surprises.

There are no subscriptions, no credits to buy, and no feature tiers. When you purchase Autotuner, you own the tool and every file you produce with it. Updates — including new vehicle coverage — are free for life. Every required cable is included in the box. What you see is what you get, and what you get is everything.

Buying through Viezu USA means you get US-based local stock with fast domestic shipping and no surprise import tariffs or customs delays. Our team provides real technical support in your time zone. Affirm and ACIMA financing are available so the tool pays for itself before you finish paying for it. We carry Autotuner because we back it — and we back it because we know how it performs in the field.

OBD / Bench / Boot Support
Read and write via OBD port, bench connection, or boot mode. Full protocol flexibility for everyday OBD jobs and deep-access work on locked or damaged controllers.

Master or Slave Configuration
Master units operate independently and can create Slave tokens for techs in your network. Slave units read and write only — ideal for satellite locations or technicians who work within a controlled dealer structure.

No Subscription, No Credit System
No monthly fees. No per-file charges. No credits. Purchase once and use it without ongoing cost or platform dependency.

Free Lifetime Updates + New Vehicle Coverage
Autotuner pushes new protocol coverage and software updates at no charge. Your tool gets better over time without any additional investment.

Every Required Cable Included
The tool ships complete. No scrambling for adapters before your first job.

US-Based Support + Local Stock
Stocked in the US. Supported by a team that knows the tool and the US market. No international freight, no customs holds, no 12-hour time zone gap when you need an answer.
