NFSX 0.2.0 ships offline firmware BIN editing and browser-based direct flashing.
Firmware tune — read and write VIN, immobilizer status, ISN, ECU number, software version, and the full UIF table from MS42/MS43 firmware BINs. Virginize the EWS pairing region for re-pairing. Checksums are automatically recomputed after every modification.
sh
nfsx tune read -f dump.bin --feature vin
nfsx tune apply -f dump.bin --feature vin --value WBAPH5C55BA123456
nfsx tune apply -f dump.bin --feature virginizeBrowser directmode — the directmode package is now browser-safe (Buffer → Uint8Array everywhere, transport interface extracted). The web app gets a functional DirectmodeView: K-line connect, probe, read (full/cal + baud selector), write with verify, and a progress bar.
