It's my opinion.
Kt200II has better hardware
Kt200 doesn't work on my laptop with win7, but KT200II works perfectly
Kt200 fails sometimes in some jobs, but KT200II never fails until now
KT200II is more stable and faster.

For me, the kt200ii offline version only works well when I put the user files into the online user folder.

 

Renault EDC17C42 TC1767, Bench mode, read/write ok with KT200II. 

I had kt200 V1 it gives quite a few errors and the software wasn't running on my PC with win7. After switching to the kt200 II it is noticeable that the hardware is superior as the errors it gave stopped giving, and the new software works 100% on my win7.

My KT200II finally works after the support passed me the right files offline server the famous USER folder, BTY if there is no connection and no function, good luck. 

I have been using kt200 and works perfectly. 
I make a new car with ECU like md1 mg1, you have to know how to use it, the people that damage ecus is because they don't know how to use it, and there are problems comes from.
