♦ CVN Bypass service

Calibration Verification Number together with CALID ( Calibration Identification ) was implemented on all ECUs that handle OBDII standard. CVN number is used to verify the integrity of the vehicle software, and manufacturers use this to determine if the calibration currently on car is in fact original. This can avoid a warranty if the numbers do not match. With our service the original CVN number remains the same after the car is tuned so when the car go to dealer for some service if they run a CVN check they will basically same number as original. Our solution will make your modified files “transparent” for diagnostic tools and it will help on not loosing warranty. We have developed and tested solutions for EDC17 / MED17 / MEVD17 from BMW group and VAG group.
