Modern ECU and TCU programming is getting harder. AutoTuner handles the protocols, communication and programming methods required to reliably read, write and unlock supported controllers so your engineers can focus on building better calibrations, features and products.
This professional Tool gives you broad multi-brand coverage through OBD, Bench and Boot across a wide range of vehicle types without locking you into a calibration ecosystem.
No flash credits. No subscriptions. No update fees. Every required cable and adapter included. Use the calibration software you already know.

Every new controller brings its own communication methods, security, software revisions and programming challenges. AutoTuner’s engineering team handles the protocol development, reverse engineering, testing and validation required to read and write supported ECUs and TCUs.
We do not write your tunes or replace your calibration software. We remove the access barrier so your engineers can spend their time developing better calibrations, custom features and products your customers actually value.
Every vehicle is different, but we're universal. We enable reading and writing through various methods. Furthermore, the Tool supports datalogging, scanning and clearing fault codes, and special operations, such as dyno mode.

Each ECU is different. Some support a Normal Read, and others support a Virtual Read. Here are more details on each.
No locked ecosystem: You can use any editor compatible with a raw binary file.
Master: Edit them on your own, or send them to a tuning file provider for adjustments.
Slave: Send your file to your master for editing.
