The Char Int 2K (for HEX-NET or HEX-V2) and Char Int (for legacy interfaces) settings also affect protocol timing. Setting this to 0 can increase the sample rate in the Measuring Blocks screen, but may cause unreliable communications with some controllers. Default values are 6 and 1, respectively.

2.2.7 KP2 Time

The KP2 Time setting applies to controllers using the KWP-2000 protocol. Decreasing this value can increase the sample rate in Measuring Blocks, but the default value of 25 should work for most applications.

2.2.8 CAN Timeout

The CAN Timeout setting defines how long VCDS waits for a module to respond. The default value of 0 should only be changed if you experience communication issues with specific controllers.

2.3 Init Parameters

Init parameters control specific aspects of the communication initialization process. These settings should typically not be changed unless you encounter specific communication problems.

2.3.1 Bypass OBD-II Fastinit

The Bypass OBD-II Fastinit option should only be checked if you experience difficulty connecting to a vehicle using generic OBD-II. The default state is unchecked.

2.3.2 Force K on Engine

The Force K on Engine option is used on Engine controllers that can use either CAN-Bus or K-line for diagnostics. Enabling this can provide faster sample rates for data logging, but it is unchecked by default.

2.3.3 Bypass CAN Init

The Bypass CAN Init option should only be checked if you do not want VCDS to connect to vehicles using the CAN-Bus. The default state is unchecked.

2.3.4 Boot in Intelligent Mode

The Boot in intelligent mode allows VCDS to quickly determine baud rates when using a HEX interface. Disabling this mode may be necessary for compatibility with some third-party software, but it is checked by default.

2.4 Reducing CPU Usage

Reducing CPU usage can improve the responsiveness of other applications running simultaneously with VCDS. However, this may slightly reduce the sample rate.

2.4.1 KWP-1281

Checking the KWP-1281 box reduces CPU usage when connected to controllers using KWP-1281, but may make the session with some control modules unreliable.
