No firmware image is loaded, so there are no values to show or edit yet. The geometry, address, scaler and axes above come from this firmware’s definition bundle and are already correct.
The file is decoded in this browser and never uploaded. A patched .bin export needs the image; map JSONC and tune export do not.
Export refused by the checksum gate.
No .bin was written. Every patched image leaves here with its checksums corrected and re-verified; there is no option to emit one unverified, because an image the ECU’s flashing tool rejects mid-write is how a brick happens. Your original .bin is untouched and still importable.
Firmware with an unpopulated checksum table.
The checksum pointer table at 0x1FBDE is blank (all 0xFF): the flashing tool that writes it has not been run on this image, so none of its checksums can be verified or corrected here.
Exporting an image with unverified checksums is blocked, to prevent flashing a bricked ECU. To get a patched image out, re-dump the ECU with a flashing tool that populates the table, then import that image and export again. Map JSONC and tune bundles are unaffected and can still be exported now.
