What (e.g., Tactrix, Kess, Scanmatik) are you using to read the files?
ToyoLex 3 is a powerful, professional-grade application designed specifically for automotive technicians and tuners who work with Toyota, Lexus, and Scion Engine Control Units (ECUs). It acts as a file modifier, allowing users to alter the behavior of the vehicle's firmware. Key Functions of ToyoLex 3:

, by contrast, is a third-party ECU editing tool focused on modifying firmware files to disable emissions and performance systems. While Techstream is designed for diagnostics and maintenance, Toyolex 3 is specifically for advanced ECU modification and tuning.
Allows for the permanent removal of specific Diagnostic Trouble Codes from the ECU, preventing warning lights for components that have been removed or deactivated [1].
A bad file write can "brick" (permanently damage) an expensive ECU. It acts as a file modifier, allowing users
: Disables the immobilizer system for Gen 1 and 2 ECUs, allowing the engine to start without a valid key. Performance Tweaks : Includes speed limiter (
: Supports various NEC and Renesas (R7F, D76F) microcontroller families.
It can permanently disable specific Diagnostic Trouble Codes (DTCs) from the ECU memory so that the Check Engine light does not illuminate for that specific fault.
