Here are two kinds of ECU Chip Tuning Tools, I collect users’ feedback from forums, and then I will show you the similarities and differences between KESS V2 V2.15 and V2.13 FW V6.070 KTAG, which may help you to buy the one you need.
*Bombas– KESS V2 obd2 is an ECU programming tool that is perfect for OBD use, BDM and all the Boot application. With KESS V2 you can program directly through the OBD port of the vehicle.
*Chason– Without any doubt KESS V2 Tuning Kit is the best tuning tool available today. It’s fast, reliable, has boot mode for EDC17 with tuning protection, excellent customer service and tech support and most importantly the coverage is fantastic.
*Tuita– Get V2.15 KESS V2 and I promise you won’t be disappointed, so many nice features that most tools just don’t have, and KESS V2 very easy to use and understand even for me.
*Serencebey– To work at with KESS V2, you had better update to Master versions. I have china clone KESS V2 v1.89. Not latest version, but it working for me. I test my K-TAG on TPROT 8/10 ECU, read/write ok, checksum too.
*Jonfre– K-Tag is perfect for J-tag, BDM and all the Boot application. With K-tag firmware you need to take apart the ECU and open it, after you can make the read/write operation

Through the table above, we know K-TAG is cheaper than KESS V2 for $6. K-TAG is available both in Master and Slave version. This way, Slave user can rely on the larger network of Master in the chip tuning field. The only thing that K-TAG does not do is OBD Communication. But for that you can count on KESS V2 V2.15.
