IXXAT Driver Installation for MPI-2 & MPI-3 | BUDS Diagnostic Setup
To establish reliable communication between BUDS diagnostic software and the vehicle ECU, correct installation of the IXXAT CAN driver is required. MPI-2 and MPI-3 diagnostic adapters use modern USB CAN communication protocols and require dedicated VCI drivers to function properly.
This guide explains how to install the IXXAT driver and prepare your computer for stable BRP diagnostics, firmware programming and ECU recovery procedures.

Overview
Modern BRP diagnostic workflows rely on stable CAN communication between the computer and vehicle electronic modules. MPI-2 and MPI-3 adapters support multiple data transfer speeds and are fully compatible with BUDS and BUDS2 diagnostic environments.
Outdated MPI-1 interfaces are no longer supported due to limitations of RS-232 communication and restricted protocol speed. For professional service operations and reliable firmware flashing it is strongly recommended to use modern USB-based MPI adapters with correctly installed IXXAT drivers.
Proper driver installation ensures stable ECU detection, faster diagnostic response and reduced risk of connection failures during software updates or calibration procedures.
IXXAT driver installation
B.U.D.S. software associated with ECM (ECU) of the vehicle through the MPI ® (Multi Protocol Interface).
Today, there are models of MPI adapters: MPI-1, MPI-2 MPI-3.
MPI-1 - is outdated adapter, able to work in three main protocols: KW2000-250k, DESS, 947-DI. Communicates with the computer via RS-232, also called a COM port. It supports almost all models 4-TEC, which support the exchange rate 250k KW2000 protocol as well as the entire line of 2-stroke technology. Due to lack of KW2000 protocol with baud rate 500k is not able to handle E-TEC technology, and some models of ATV Can Am. Since most modern laptops no longer has an RS232 serial port, must be used an USB to RS232 adapter. There are many USB-to-RS232 adapters, and each has its own driver.
MPI-1 adapter is no longer supported by software.
MPI-2, MPI-3 - a modern USB adapters, which uses the protocol CAN, supports transfer rate of 25 to 1000k. For the diagnosis of BRP vehicles used KW2000-250k and KW2000-500k. As a standalone unit, supports 4-TEC and E-TEC vehicles. With the additional device DESS Post Interface (P/n 529036019) supports the full range of vehicles BRP, including 2-stroke technology.
The latest software B.U.D.S. only works with MPI-2, MPI-3 adapters.
To use MPI-2, MPI-3 adapters with your PC/laptop, driver IXXAT must be installed.
1. Download the IXXAT driver for MPI-2, MPI-3 adapters: vci 3.5.2 4268.
or
2. Download the IXXAT driver for MPI-2, MPI-3 adapters VCI_Setup_4.0.939.0
Start the installation by double-clicking on the downloaded installer file.
