Reversed the inner map format from l.java (Nc/Lb) and validated it against the
stock reference maps:
- reconstruct_rom.py: decoded map -> unpack directory -> 384KB flat ROM. In the
flat ROM, production (20187) vs aftermarket (20188) differ only 1.4% (vs 96%
packed), i.e. real fuel enrichment.
- table_map.py + TABLES.md: fe = c.a[Qd*48]; base = (fe[0]&0x2F0)<<12 = 0x50000;
table = base + fe[k]. Located 9 tables (main/low-throttle fuel per cylinder,
base/idle fuel, ignition by gear x4), 32 RPM rows x 20 throttle cols, with real
axes (RPM fe[8], throttle fe[27]) and the AFR curve (fe[2], 128=lambda 1.00).
Validated: main-fuel delta is uniformly richer in the aftermarket map.
Viewer now has a "Triumph tables" tab: drop a real .hex (or pick two) and it
decodes, unpacks, and renders the fuel/ignition tables as heatmaps with real
axes, plus an A->B difference view. build_viewer.py embeds the c.a/s.a directory
so any map resolves in-browser.
Catalogue dropdown: download_maps.py fetches map .hex files into maps_cache/;
serve.py serves the viewer over http so the dropdown can fetch them (drag-and-drop
still works on file://).
Proprietary map binaries (*.hex, *.dec.bin, maps_cache/) are gitignored — code and
docs only.
