October 26, 2023 Subject: ECU Tuning and Diagnostics Coverage Analysis Tool Focus: KT200 ECU Programmer 1. Abstract This paper provides a technical overview of the ECU (Electronic Control Unit) support list for the KT200 programmer. As the automotive aftermarket shifts toward "bench" programming and OBD (On-Board Diagnostics) tuning, technicians require clear data regarding vehicle coverage. This document categorizes the supported ECUs by brand, protocol type (OBD vs. Bench), and microprocessor architecture, while highlighting the distinctions between the KT200’s internal capabilities versus generic "slave" tool limitations. 2. Introduction The KT200 has emerged in the market as a cost-effective solution for ECU reading, writing, and cloning. Unlike older generation tools that relied solely on soldering or JTAG connections, the KT200 emphasizes "Bench" programming—reading ECUs removed from the vehicle via a universal cable without opening the ECU case.
