Many tuners prefer version 2.23 because it is considered the most stable "offline" version for older firmware. It supports a vast range of protocols for ECU remapping and OBDII flashing without the overhead of the newer, subscription-based cloud features found in KSuite 3.0+.
KSuite 2.23 is frequently bundled with "clone" hardware. Using clone software/hardware is a common practice in the aftermarket but carries risks of hardware failure or ECU damage if used improperly. ksuite 2.23 download
