ByteShooter — Master ECU Programming Suite 3.20

ByteShooter is a legacy master ECU-programming suite for technicians who already have compatible ByteShooter hardware. The software organizes supported operations by vehicle, engine and ECU and separates passenger-car and truck loaders, while the actual read, write and checksum functions depend on the connected interface and licensed hardware modules.

Supported vehicles, ECUs and files​#

The supplied interface shows manufacturer and vehicle selection for car and commercial-vehicle work, including visible entries for Suzuki, Toyota, Vauxhall, Volvo and Volkswagen. Controller support is module-dependent: manufacturer documentation describes EDC16 checksum correction and optional families such as MED17/EDC17 TriCore and VAG DSG DQ250. Those examples explain the ecosystem; they do not prove that every optional module is activated by this package.

• Passenger-car and truck workflows through the separate LDRcars and LDRtrucks loaders.
• Master mode, where an open binary can be saved for calibration work, plus hardware-dependent slave and semimaster workflows.
• Vehicle, engine and ECU choices exposed by the installed database and the licenses present in the connected ByteShooter interface.

Functions​#

• Identify a supported vehicle and ECU path, then expose the appropriate read or write operation.
• Read ECU content for backup or calibration and write a prepared file through supported hardware.
• Apply checksum handling only where the selected licensed module explicitly provides it.
• Use the included PDF as the starting point for cable, ignition and programming procedures.

System and hardware requirements​#

• A Windows workshop computer and genuine compatible ByteShooter programming hardware.
• Correct USB driver and hardware firmware; this archive does not include a USB driver installer.
• The required ECU/module license for the selected controller family.
• Stable vehicle voltage, correct cable or bench pinout and a recoverable original read.

Recommended workflow​#

1. Identify the ECU from its label and diagnostics before selecting a vehicle entry.
2. Confirm the hardware connection and licensed module with a read-only identification operation.
3. Create and verify a full backup before editing or writing any calibration.
4. Validate file size and checksum support, maintain power, and follow the controller-specific instructions during programming.

Package contents​#

Included are the main ByteShooter executable and configuration, separate car and truck loaders, a PDF manual and the supplied license text. All three executable files are unsigned and were inspected without being launched.

Important limits​#

There is no reliable universal vehicle list for a legacy installation because support also depends on hardware generation, firmware and purchased modules. Treat the on-screen ECU selection and a successful identification as the final gate; do not assume support from make and model alone.
