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.
