Tips from pros here, about a ECU programmer comparison tablet, incl. MPPS v18, ktag, kess, fgtech galletto 4 or fgtech2… Mainly differs from communication/ protocols. Hope this helps.

Mpps v18 vs. Kess v2 vs. K-tag vs. Fgtech

ECU tools/




FgTech2 /
Fgtech 4






So, KESS v2 supports obd2, boot

MPPS v18 works for obd2, Multiboot, Tricore for Marelli ECU’s

KTAG can work for bdm, j-tag, boot

FgTech Galleto v54 4 (or Fgtech 2)work no issues with obd2, bdm, j-tag, boot


ECU tools





FgTech2 /
Fgtech 4

So, 3 options are available for OBDII connection: mpps v18, kess, fgtech

3 options for BOOT: kess v2, k-tag, fgtech galletto

2 options for BDM: ktag, fgtech

2 options for JATG: ktag, fgtech 4/2

Only 1 way for Tricore: MPPS V18!

That is why you need to buy more than one ecu programmer.

When to buy Galletto 4 and kess v2 together?

Galletto 4 works with truck, including Benz truck, read and write ECU via both BDM and OBD; KESS not works with truck, read and write ECU via only OBD, not BDM.

When to buy Kess v2 and Ktag together?

KESS V2 is an ECU programming tool that is perfect for OBD use, while KTag is perfect for Jtag, BDM and all the Boot applications (tricorne and ST10).

With KESS V2 you programming directly through the OBD port of the vehicle, while with Ktag (Ktag 2.13) you need to take apart the ECU and open it after you can make the read/write operation.

Many ECU has the advantage that can be read and write from OBD port (so KESS V2 is perfect), but there are lot ECU that needs to disassemble from the car and open and this is the case for all the ECU that need to be programmed with Jtag, BDM and Boot protocols, so KTAG is needed.

When to buy Fgtech 4, Kess v2 and Ktag all together?
Because none of China tool will cover all cars well and if you buy clone tools, buy all (galletto+kess+ktag)from them, that you will cover more cars, or better to buy a good original tool if you will do the work as a pro, all depends want you will do.
