Built by the honda-profile-research workflow (per-vehicle research ->
synthesize -> adversarial-review) and validated through the loader (every
formula compiles, presets resolve, decoders sane):
- honda-crv-2.4-2007.json ISO 15765 CAN, MAF + wideband A/F (lambda),
single-bank K24Z1 i-VTEC, 19 PIDs, 39 DTCs.
- honda-odyssey-3.5-2022.json ISO 15765 CAN, MAF, dual-bank J35 V6 (STFT/LTFT
B1&B2 + 4 O2/AF sensors), 31 PIDs, 83 DTCs.
Standard SAE Mode-01 PIDs (all verified) + gauge zones on ECT/RPM/BATT;
Honda enhanced Mode-22 PIDs omitted (no public source pairs a documented PID
with a verified formula for these -- Honda uses proprietary HDS). Web-
researched, not yet read on the actual vehicles.

Gauges:
- Optional per-metric warning zones (warn_hi/redline_hi/warn_lo/redline_lo) in
the profile schema; gauges draw colored redline/warn bands and color the
needle + readout by zone. Default neutral when unset (no false redline).
- Removed the value progress-arc fill (it dominated the dial / looked wrong) ->
clean tach face: bezel, ticks, numeric scale, needle, redline band, readout.
- Auto-derivation rejected: bad direction/threshold vary per metric, so zones
are config (with a sensible neutral default).
Units:
- New Units menu: Temperature C / F. Converts gauges, graph, table, and PID
browser (values, scale, zones, unit labels) at display time; data stays C.
Ford 6.0 profile: zones for ICP (red<500), FICM (red<40/amber40-48/green48+),
ECT/EOT (high redline), RPM (redline 3800), boost, battery; tightened FICM
(38-52) and battery (9-15) ranges so redline bands land sensibly.
Docs: profiles/PROFILE_SPEC.md -- canonical, AI-agent-ready profile spec
(schema, formula language, zones, confidence, rules); README points to it.
Validated headless: zones parse/classify, F conversion (112C->233.6F, zones
converted), gauges render; obdcore + diagnostics tests pass.

Rename: the app is vehicle-agnostic, so 'ford-obd' was wrong. Rebranded all
code/docs/profile authors to OBDash; Gitea repo renamed justin/ford-obd ->
justin/obdash (remote + description updated). Ford the make and the
ford-6.0-powerstroke profile are unchanged (that vehicle really is a Ford).
Multi-axis upgrade (per request):
- MultiAxisPlot now gives each METRIC its own Y axis, each axis colored to
match its line; the primary metric owns the LEFT axis, others stack right.
- Click a line to promote it to the left axis (sigClicked -> set_primary).
- Cleaner teardown (no removeItem warnings); axis label no longer doubles the
unit; Normalize round-trips.
Validated headless: colored per-metric axes, promote-to-left, gauge view,
normalize toggle, profile switch; obdcore + diagnostics tests pass.

Built by the vehicle-profile-research workflow (per-vehicle research ->
synthesize -> adversarial-review pipeline) and validated through the real
profile loader (every formula compiles, presets reference valid keys):
- jeep-wrangler-4.0-1997.json ISO 9141-2, speed-density MAP, 13 PIDs, 26 DTCs
- ford-mustang-cobra-4.6-1996 SAE J1850 PWM, MAF, 20 PIDs, 46 DTCs
- ford-mustang-gt-4.6-1996 SAE J1850 PWM, MAF, 18 PIDs, 57 DTCs
- mercury-mountaineer-4.6-2006 SAE J1850 PWM, MAF, 20 PIDs, 48 DTCs
All are standard SAE Mode-01 PIDs (vehicle-appropriate: MAP vs MAF, correct
O2/trim banks) + the BATT atrv pseudo-PID + manufacturer-specific DTCs.
Sourced from web research, NOT yet read on the actual vehicles -- confidence
reflects sourcing. Protocol is auto-negotiated by the ELM327 regardless, so
the Mountaineer PWM-vs-CAN note is informational.

Vehicle data is now DATA, not code. PIDs/scaling/DTCs/presets live in
profiles/*.json; the app loads them at runtime, so it works across vehicles
and others can contribute profiles (open source).
Core:
- obdcore/formula.py: safe AST evaluator for scaling formulas (A/B/... byte
vars, Torque/FORScan convention). Only arithmetic/bitwise + min/max/abs/
round/int/float; names/attrs/arbitrary calls rejected at load -> a community
profile CANNOT execute code.
- obdcore/profile.py: load/save/list profiles; compiles each formula into a
decode callable. registry.py now profile-backed (PidRegistry/DtcDatabase
take a Profile); hardcoded Ford table removed.
- store.py: clear()/snapshot()/export_csv() for capture management.
Profiles:
- profiles/ford-6.0-powerstroke.json (27 PIDs, verified formulas, DTCs)
- profiles/generic-obd2.json (standard SAE Mode-01 base, any vehicle)
- profiles/README.md (schema + formula language + contributing)
GUI:
- Menu bar: File (new/record/export/replay capture, quit), Profile (switch/
load/import/reload/edit-JSON/export, live profile list), View (Graph/Table
views, gauges P2, toggle PID dock, normalize, light/dark theme), Help
(about/confidence legend/profile info).
- PID browser + presets rebuild on profile switch; added Table view; raw-JSON
profile editor dialog (validates schema+formulas before saving).
Tests: profiles load+compile, formula sandbox rejects hostile input, decoders
still match real truck bytes, crank/derived/dead-PID/replay -- all pass.
