Ktag v7.020 ecu programmer review:

I confirm the new KTM100 K-TAG is compatible with J-Tag, but in a completely different way. Usually J-Tag programmers are available only for big productions, never present in chip tuning devices. Using only the essential components, Alientech have merged J-Tag, Motorola BDM/Nexus and Bootloader Mitsubishi/Infineon Tricore/ST communication lines into a single product.


This KTM100 K-TAG works perfectly. Its easy to learn how to use K-TAG takes almost no time, because all the communication protocols operate along similar principles. Once you have learned to use a protocol, you will naturally use all the others. Alientech knows what it means to work in motion. For this reason the research methods of the protocols and choice of vehicles are detailed and ordered.


Unlike many ECU programming tools, with K-TAG you have at your disposal only the applications you really need. Once you have the hardware, you can choose which group of protocols to enable and then start working. In this page you can find a complete list of the ECU currently supported by K-TAG.
