Reversed the device-flag mechanism (l.java lc() + ee bit logic) and validated the
flag locations against a real reference map: 20188Map2009AIRBOXBONNY (explicitly
"NO SAI, NO O2 SENSORS"). Diffing its flat ROM vs stock 20188 isolated exactly
three byte-boolean flags that flip 1->0:
0x53801 SAI (= base + fe[33] + 0x00)
0x53818 O2 sensor (+ 0x17)
0x53819 O2 sensor (2) (+ 0x18)
1 = enabled, 0 = disabled. Neither stock map could reveal these (both have SAI+O2
on); the delete map was the key. See research/reference-maps/DEVICES.md.
Viewer: the Triumph-tables tab now has a Device flags panel — checkboxes reflect
the loaded map's real state (stock: all on; delete map: all off), toggling flips
the byte, and "Export edited .hex" re-encodes the distribution format. The
decode->edit->encode round-trip is byte-exact (verified). The caXX header bytes
are map-ID metadata, not a cal checksum; the ECU-flash checksum is applied at
write time.
