Received KT200 Kit (ECUHELP KT200 and HTprog Clone Adapter) from ecuhelpshop, then have a test to read/write EDC17C55 with no problem.

Look at HTprog Clone Adapter, it is turned on with a red flash.

Look at Bench,I connect KT200 and HTprog Clone Adapter, and the EDC17C55 ECU box.

Then I try to read P-Flash, it is completed.
Attach 3 images to show the result.

Alright, the Job is done.
I will keep on updating more test results of KT200 and HTprog Clone Adapter.

BTY, I am informed that the ECUHELP HTprog is reworked and even if you have no KT200, it will work more stable, hope this news helps you a lot.
