The KT200II is a very good ECU tool in terms of quality/price. You just need a good internet connection and a good 12v power supply of 13amp or more.

 

I use kt200 to read a few edc15c2 on bench, 3 connectors, and 1 connector.

KT200 V2 is an excellent ECU tool—it has never failed or bricked an ECU for me. I always use it with automatic checksum calculation and all works flawlessly.
For newer ECUs like MD1 in VAG and BMW, it works perfectly.
 

I’ve had the KT200 for over a year and the KT200 II for a few months. Together, they read/write around 30 ECUs for me. Most on bench worked well, but about half of the OBD connections didn’t succeed. You also need a good internet connection. Overall, considering the price, it’s not a bad tool.
