Why buy from a tuner
Most shops sell you a box. A slave is only as good as the master behind it.

Slave or master
Which one do you need?
If you are not writing maps yourself today, a slave is the tool: lower price, and every file done by people who tune for a living. You can upgrade it to master later.
Slave or master, explained| Question | Slave Files by MMT | Master |
|---|---|---|
| Who writes the map | MMT, in house | You, in your own tuning software |
| Files you can open | Read and write; tuning goes through MMT | Every file you read |
| What you need | The tool and a laptop | Tuning software and calibration experience |
| Tool price | Lower | Higher |
| Upgrade later | Slave to master, per protocol group | — |
| Best for | Workshops and mobile tuners who want every file done right | Experienced calibrators |

What is the difference between a KESS3 slave and a master?
A master tool opens and saves any file it reads, so you write your own maps in tuning software. A slave tool is linked to one master: the files it reads go to that master to be tuned, and it writes back only what that master sends. Buy a slave from us and that master is MMT.
What do OBD, bench and boot mean?
OBD reads and writes through the diagnostic socket with the ECU still in the vehicle. Bench connects to the ECU out of the vehicle, through its connector. Boot opens the ECU and connects to the board, for units that cannot be read any other way. KESS3 does all three in one tool, for the protocols that are active on it.
Which vehicles does KESS3 cover?
Protocols are sold by vehicle group: cars and LCVs; bikes, ATVs and UTVs; agriculture, trucks and buses; marine and PWC. Coverage is decided ECU by ECU, so check Alientech’s official vehicle list, or send us the ECU reference on WhatsApp and we will tell you before you buy.
Is there a subscription?
Each protocol licence comes with a subscription period that brings Alientech’s updates and new vehicles; renewals are sold separately. Every kit on this site lists exactly what is in it.
How do I get my files back from MMT?
Read the vehicle with your KESS3, upload the file to your MMT portal, and MMT tunes it in house. You get a message when it is ready, download it from the portal and write it back with the same tool.
