BLUEPRINT STUDIO 0.2.0

A real Windows logger and calibration workspace—built toward safe ECU programming

Blueprint Studio now has a native Windows J2534 bridge for guarded standard OBD logging, exact VIN and modified-build snapshots, a definition-driven calibration workspace, complete change history, original-file fingerprints, and a hard bench write/recovery gate.

BLUEPRINT LINK DEVICE

How we build our own OBD tuning interface

1. Prove the softwareUse a reputable J2534 pass-through first so the PC logger and controller profiles are validated independently of a new circuit board.
2. Build read-only hardwarePrototype protected power, USB-C, CAN/CAN-FD, GM J1850 VPW, K-Line, voltage sensing and SD logging.
3. Earn bench writingAdd a physical BENCH state only after signed firmware, identity checks, stable power and intentional recovery tests pass on spare controllers.
01

Read-only J2534 logging

Probe a registered Windows pass-through and log whitelisted Mode 01 data through GM J1850 VPW or 11-bit 500 kbit CAN. Security, erase and programming services are not exposed.

02

Definition-driven calibration

Blueprint edits only parameters whose definition supplies an exact address, data type, scaling, unit and safe range. The included synthetic demo cannot map or flash a real ECU.

03

Auditable vehicle projects

Every log and change manifest preserves the VIN, controller, operating system, modified build sheet, original-file fingerprint and before/after values.

04

Blueprint Link device plan

The download includes the hardware architecture, first prototype bill of materials, USB command protocol and firmware safety states for our planned USB-C OBD interface.

HOW IT WORKS

From symptom to measured proof

  1. Download and extract Blueprint Studio on a Windows computer with Node.js 22 or newer.
  2. Run start-blueprint-studio.cmd; the first launch installs the pinned native bridge dependency.
  3. Install the official driver for a compatible J2534 device, probe it, and test read-only logging on a protected bench before a vehicle.
  4. Use the safe demo to test calibration editing and change manifests while the real P59 definition, checksum and write/recovery path remain locked.
