3.1 TOAD Pro

TOAD Pro package

TOAD (Total OBD & ECU Auto Diagnostics) PRO contains advanced, comprehensive, and powerful “car-manufacturer-approved” OBD software applications. It performs a thorough health-check on your car and diagnoses 15,000+ common problems. It can also “hack” car performance and optimize fuel consumption with included ECU remapping software (for geeks).

This software is usually reserved for registered and acclaimed car repair shops, manufacturers, servicemen, and mechanics, but TOAD makes it publicly available. Its biggest strength, besides wide car compatibility, is that the software lets you monitor live data with customizable visual graphs.

TOAD is suitable for home car owners willing to save hundreds of dollars by finding and fixing issues themselves, or for professional car mechanics/service shops needing the latest cutting-edge detection and analysis software that keeps drivers safe. Law enforcement agencies, franchise car shops, serious car enthusiasts, regular car owners, and car manufacturing companies in about 80 countries worldwide use TOAD.

Benefits of TOAD PRO:
