Why KESS3
Why dealers choose the KESS3
For dealers who tune more than cars: the coverage across bikes, marine, agricultural and trucks is unmatched.
What it does
OBD, bench and boot
OBD
Read, write and virtual read: if a real read is not available the suite downloads the original file from the Alientech data bank by ECU ID. Checksum correction on every write, and a recovery function if a write is interrupted.
Bench
Read, write and clone on the bench, plus boot mode and service mode for the ECUs that need them.
Boot
Infineon TriCore; Motorola MPC5xx, MC68xxx, HC12, Nexus MPC5xxx and MPC56xxx; NEC 76F00xx (NBD Toyota); Renesas SH705x and M32; Mitsubishi MH7xxx and MH8xx; ST ST10.
Software
K-Suite manages the tool, the protocol groups and the subscription in one place. Buy the protocol groups you need now and add more as the work comes in.
Slave or master
Which version?
A slave KESS3 reads and writes files encrypted to our file service: cheaper, simpler, and the tuned file comes back ready to write. A master version gives you the decrypted file to edit or send anywhere. Most new dealers start with a slave and never need more; tell us what you plan to do and we will say which.
