Checksum by KT200 II OK 

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 II Read/Write OPEL ZAFIRA 2.0 170hp Delco E98 Full System.
 

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.
 

With the VAG DCM6.2V, the virtual read and OBD write with automatic checksum correction worked flawlessly. For PSA SID807/807Evo, the OBD real read and write with checksum correction also worked perfectly. So far, the KT200 II has been working great with OBD protocols.
 

I've tried a few ECUs via OBD—V50 Valeo and SID807Evo worked perfectly, and a 2016 C4 Grand Picasso (I don’t remember the exact ECU) also worked good. The KT200 II is a great ECU programmer.
 

I have the KT200 II from ECUHELP, and so far,  it’s been working great. I've done more than 20 ECUs, and works well. You do need a powerful, high-quality lab power supply, but that's true for all ECU programmers. I really like the KT200 II's bench mode—it's really helpful and often reduces the time needed for reading/writing.
Note: So far, I’ve only worked on table (bench mode, boot mode) and haven’t tried OBD yet.
 

 I believe the KT200 II is the best tool for its price. I've done around 40 ECUs without any issues. My KT200 V1 bricked one ECU, a Delco E98, but I later discovered the problem was due to the power supply. After switching to a lab power supply with stable voltage, all worked perfectly.
 

I have the KT200 II online version and read/write about 50-60 ECU. All work perfect. 

 

So far, I haven't encountered any ECU that the ECUHELP KT200 II couldn't read or write. For instance, with the Volvo EDC15C11, neither the Galletto V54 nor Ktag could read it, but the KT200 II worked like a charm. The documentation and manuals are clear and easy to understand. It was my best purchase last year.
