tsunagi-matrix

Read, back up, repair and rewrite the M35080 EEPROM in a BMW E46 instrument cluster, over an Arduino SPI bridge on Web Serial.

TSUNAGI///Matrix — the BMW E46 M3 tools' calculations as a library, CLI and MCP server: MSS54HP BIN + Testo log → VE and rf_korr corrections, locally. MIT

E46M3SMG2 /// MAPPING — read, edit and check the E46 M3 SMG II calibration in the browser (TSUNAGI///Matrix, MIT)

E46M3 /// MONITORING — BMW E46 M3 diagnostics in the browser over DS2/K-line (Web Serial on desktop, WebUSB+FTDI on Android). Code only: the SGBD-derived ECU tables are generated locally, not published.

MSS54HP CSL CONVERT /// BOOT — back up an E46 M3 MSS54HP DME and plan its CSL conversion over OBD (TSUNAGI///Matrix, MIT)

Tune a CSL-converted BMW E46 M3's MSS54HP DME from your own drive logs — Alpha-N VE from lambda, checksums corrected, direct DME read/log/flash over K+DCAN. Runs in the browser. (TSUNAGI///Matrix, MIT)
