Thread: Kess v2 Slave & Master any difference & how to convert
If you have a master version you can work directly on the program you have write on the vehicle (tuning, egr off, ….) and rewrite after directly.
If you are a slave version (who depend of a master (who do modificated), you read the program (crypted by genius), you send it to the master, he do what you what (money paid) and he re-sent to you to write in the ecu machine.It is expensive for the slave version user who depend of a master.
Kess v2 slave into master:
clone kess v2 floods the market is why there is lots of genuine kess slave for sale, plus most slaves cannot do boot mode
the advantages of using original kess v2 and converting it is that you have genuine original kess hardware, so the chances of hardware failure is smaller
if you can fit genuine nxp chip then great, otherwise you will converting to Chinese NXP with the Chinese firmware
advantages are that converted unit does boot mode, and in some cases have more protocols, you already said yourself you want more freedom, and likely better tuning files!
If you’re not equipped with rich tech knowledge & experience, forget it and escape from risk. Just buy a kess v2 china clone master version:

A BMW X5 E70 3.0L 2008 model year with a burning on the dashboard, the CHECK ENGINE indicator flashes and failures:
29F4 – Catalytic-converter conversion
29F5 – Catalytic-converter conversion (Bank 2)
Poor performance of the catalyst, decided to cure a dynamic version of the firmware.
How was the process of chip tuning BMW X5 E70 3.0L
The engine in this vehicle control unit controls the Siemens MSV80 . For reading and writing of EEPROM unit used KESS V2 master ecu programmer , which work indiscriminately passed ECU through the vehicle diagnostic connector.
The process is not fast, so be sure to connect the charger.
KESS V2 connect to the car.
Read the firmware of ECU.
And records the dynamic version of the software, with a fall in the rate of toxicity.
firmware version is optimized for standards Euro2
allows the complete removal of the catalyst and a second oxygen sensor
reduced opening temperature of the thermostat at partial loads, from 110 to 100 degrees Celsius
turns off the fuel supply of 7200 rev / min
maximum power increased from 272 kW to 305 kW
Torque increased from 315 Nm to 353 Nm
