The K-Tuned All-In-One Adjustable VSS Converter is designed as a programmable speed correction unit intended for installation within a vehicle’s engine harness, near the engine control unit (ECU). The device simplifies speed signal adjustments, offering pre-configured settings for specific vehicle modifications, as well as a general-purpose setting for custom calibration. Installation involves connecting four wires: power, ground, speed signal input, and speed signal output. Programming is accomplished via a USB connection to a Windows-based computer using a dedicated application.
Device Overview and Functionality
The K-Tuned VSS converter consolidates previous K-Tuned VSS units into a single, versatile device. It addresses speed signal discrepancies that can arise from engine or transmission swaps, or cluster modifications. The converter’s primary function is to accurately calibrate the vehicle’s speed signal, ensuring correct speedometer readings and proper operation of related systems. The unit is designed to be safely positioned within the vehicle’s interior, protected from external elements.
Installation Procedure
Installation of the K-Tuned AIO-VSS Converter is described as straightforward, requiring connection of four wires. These connections are: power, ground, speed signal input, and speed signal output. The converter is supplied with a plug-in harness for easy connection and disconnection. A jumper plug is also included, allowing the input and output signals to be reconnected to stock configuration if the unit is temporarily removed. The documentation specifies installation within the engine harness, in close proximity to the ECU. Specific instructions are available for 02-04 RSX models, with notes regarding differences for 05-06 models. The converter includes a detachable plug-in harness and a separate USB harness for programming. Detailed installation and programming instructions are provided with the unit.
Wiring Specifications
The K-Tuned AIO-VSS Converter requires four wire connections for operation:
- Power
- Ground
- Speed Signal Input
- Speed Signal Output
The documentation emphasizes the simplicity of the wiring process. The provided harnesses facilitate connection and disconnection, and the unit is designed for placement within the engine harness, ensuring a secure and protected installation.
Programming and Configuration
The K-Tuned AIO-VSS Converter is programmable via a USB connection to a Windows-based computer. A dedicated computer application allows users to select from three pre-defined settings, or to enter custom correction values. The available settings are:
- RSX Setting: Converts the VSS signal from 05+ models to the specifications of 02-04 models.
- S2K Setting: Specifically corrects the speed signal for S2000 cluster swaps.
- General Setting: Allows for custom correction values to be entered, providing flexibility for a wider range of applications.
The RSX and S2K settings are pre-configured based on a 23-inch tire size (205/50R15) and are adjustable by up to 25% in either direction for precise calibration. The General setting allows users to input any desired correction value, also within a range of 25% positive or negative adjustment.
Preset Configurations and Tire Size Considerations
The pre-configured RSX and S2K settings are optimized for vehicles utilizing a 23-inch tall tire, specifically a 205/50R15 size. However, the documentation notes that these settings are adjustable by up to 25% in either direction. This adjustability allows for accurate calibration even when using tires of different sizes. The General setting provides complete control over the correction value, enabling users to fine-tune the speed signal for their specific setup.
Compatibility and Applications
The K-Tuned AIO-VSS Converter is designed for use in vehicles undergoing engine or transmission swaps, or those with modified cluster setups. It specifically addresses compatibility issues arising from differences in VSS signals between various model years and vehicle configurations. The converter is applicable to scenarios involving:
- RSX swaps requiring conversion of 05+ VSS signals to 02-04 specifications.
- S2000 cluster swaps needing speed signal correction.
- General speed signal calibration for vehicles with out-of-calibration speedometer readings.
