KTAG V7.020 review Yes and No:

I try with edc16c31 smart 451, read write in bdm ok with ktag, read write ok in obd with kess.

I tested with a lot of edc17 in these day and read and write without problem.

I made a video with a edc17c50 bmw 120d f21 with gpt, read and write ok.
I have a fiat edc17c69 virgin (without software inside), this I can’t read.


My Ktag 7.020is able to read and write EDC17C69


7.020 version runs faster and more stable.


Ktag 7.02 good working. no problem.


Ktag master 7.020 displays diagrams via words, not pictures. It’s better to understand0


I tried to read Bosch edc17c69 gpt Fiat 500X and not working, with ktag ori read and write ok.


I read a lot of edc17 and few edc17 with gpt and all read and write ok maybe there is a bug in sw/fw from alientech.
virtual reading is = servidor ALIen.
virtual reading id ecu , and download firmware.
Not real soft.

I compared 7.020 with my old 7.003. KTAG 7.020 adds 100+ ECU types and supports new car models e.g. Toyota 76FXXX, PSA 17.4.4, Ford E83, VW 17.5.5 (1766), Mercedes-Benz 276 ECU, Toyota 76F, etc. It should be a good budget i think.
