Live demonstration using KESS to read/write data to car.

KESS V2 chip tuning kit (latest 2017v) let's you quickly, easily and safely tune car performance and modify it's systems behavior in 4 easy steps as shown below...

It let's you download vehicles ECU chip data (even if it's encrypted, like on new cars) - which you can then modify using a car map editing software.

Once edited, upload the data file back to car and see immediate changes with performance, dynamics, component behavior, etc.

Here's how it works in 4 steps...

STEP 1: Plug KESS into car's OBD-II port

STEP 2: Plug KESS into laptop's USB port

STEP 3: Launch KESS software

STEP 4: Read/Write data to vehicles EEPROM ECU chip

Who's it for?...

It's either for home car owners who'd like to save on fuel, improve horse power, adjust driving comfort (like RPM to gear change)...

Or for high-tech advanced car technicians/tuning shops who already tune for customers and need a tuner with a much larger vehicle support. Or even if you'd like to start tuning for money... since it's a highly profitable business... and you can easily charge up to $1000 - $2500 per tune.
