My mods: save, undo and test your own changes
Changing a setting, swapping a part or trying a tune is only half the job. The other half is knowing what it did. My mods keeps each change you make as a card for your car:
- Apply and revert. Store the commands that make the change and the ones that undo it (from your brand tool or a community guide you trust). Each run asks for confirmation, and changes are blocked while the car is moving.
- Parts and tunes too. No commands needed: mark it modded when you install it and stock when you take it off.
- Record a test. Pick up to 4 sensors (presets for engine basics, fuel trims, performance, economy, cooling and charging), choose 30 seconds to 5 minutes, and label the run stock or modded.
- Compare. A table shows the stock and modded averages side by side with the change in %. Every extra run is averaged in, so the result gets more reliable each time.
- Try new values. Copy a mod to test a different value without losing the original and its history.
- Back up and share. Export your mods to a file and import them on another phone.
38 live sensors
Torque Deck asks your car which of these it supports and only shows those. Every one can be a dashboard tile, a driving-mode tile, a graph line or a My mods test sensor.

14 accessory guides
⛰ Lift / leveling kit + bigger tires
The most common truck/SUV mod. Larger tires make the speedometer and odometer read low, and can confuse shift points and ABS.
- Run the GPS speedometer check before and after recalibration. Aim for within 1–2 mph.
- Brand tools: FORScan (Ford), AlfaOBD/JScan/Tazer (Jeep/Ram), tuner or calibrator (GM/Toyota).
- Read codes afterward: an ABS or “tire size mismatch” code means recalibration is incomplete.
💡 LED headlights & turn signals
LEDs draw less current. Cars that monitor bulbs may show bulb-out warnings or rapid "hyper-flash" turn signals.
- Read codes after install. Lighting faults often appear as body (B) or network codes.
- Fix hyper-flash with a coding change (brand tool) or proper resistors/decoders.
- Aim headlights after any swap so you don’t blind oncoming drivers.
🔋 New or upgraded battery (incl. dual battery)
Many modern cars track battery age and adjust charging. Some (BMW, VW, many Fords) need the new battery registered.
- Charging test: about 12.6 V engine off and 13.7–14.7 V running is healthy.
- Battery registration/reset is done with the brand tool (BimmerCode, OBDeleven, FORScan).
- After a battery swap, readiness monitors may reset. Check before inspection.
⚡ Light bars, winch, fridge, inverter
Big electrical loads can outrun the alternator at idle or drain the battery overnight.
- Charging test with every accessory on: voltage should stay above ~13.2 V while running.
- Drain watch overnight-style: leave the adapter plugged in and watch voltage fall with everything off.
- Fuse every circuit at the battery.
🌬 Cold-air intake
Changes the airflow the MAF sensor reads. A poorly matched intake causes lean conditions and P0171/P0174.
- Fuel-trim watch: long-term trims should settle within about ±5–8 %.
- Oiled filters can contaminate the MAF sensor. Watch the MAF reading at idle.
- In California and other CARB states, choose parts with a CARB EO number.
💨 Cat-back / performance exhaust
Cat-back systems are usually code-free. Anything ahead of the catalytic converter can trigger O2 and catalyst codes.
- Watch O2 sensors and trims for a few drives.
- Never remove catalytic converters or emissions equipment. It’s illegal and will fail inspection.
- Check readiness monitors before an emissions test.
🏁 Performance tuner / programmer
Changes ignition timing, fueling and shift points. The biggest gains and the biggest risks.
- Performance monitor: watch timing advance for sudden drops (knock), IAT and fuel trims.
- Save the stock tune before flashing, and return to stock before dealer visits.
- Use emissions-legal tunes only. Deletes and defeat tunes are illegal.
🚚 Hitch, trailer wiring & brake controller
Towing adds heat and load. Some trucks need the trailer module enabled in configuration.
- Towing monitor: coolant temp, engine load and intake temp on grades.
- Trailer-module enable/brake gain settings come from the brand tool (FORScan, AlfaOBD) or the dash menu.
- Read codes if trailer lights misbehave. Lighting faults show up as body codes.
🔑 Remote starter / alarm
Installs tap into the immobilizer and CAN network. Bad installs cause network codes and battery drain.
- Read codes after install. Several U codes together point at the install.
- Run a drain watch: the module should go to sleep within ~20–60 min.
- Combined code search on the Codes tab helps here.
📹 Dash cam (hardwired / parking mode)
Parking mode keeps recording with the engine off and slowly drains the battery.
- Drain watch: see how fast voltage drops with the camera in parking mode.
- Set the camera’s low-voltage cutoff around 12.0–12.2 V.
- OBD-powered cams share the port with this adapter. Use a splitter.
📱 Aftermarket stereo, CarPlay & backup camera
New head units and camera retrofits connect to the car’s network. Some features need coding to activate.
- Read codes afterward: missing-module U codes are common after a radio swap.
- Feature activation (camera, video settings) is done with the brand tool.
- Check for parasitic drain if the battery dies after the install.
🧳 Roof rack, cargo box, tonneau cover
Racks and boxes add drag. Tonneau covers can help on trucks. Measure the real effect.
- Economy A/B test: reset the trip, drive the same route with and without, and compare average mpg.
- Keep speed and route consistent for a fair test.
🎛 Digital dash & instrument cluster
How much you can change the factory digital gauges depends on the brand. Some have it in the settings menu, some unlock more through coding, and some lock it down entirely.
- Check the built-in settings first. Mustang has MyColor gauge colors and selectable gauges, and many Fords have Settings → Configure Gauges.
- Ford (FORScan): owners change which gauges appear in the cluster (IPC) by editing its configuration. Back up the IPC first. Raptor owners report gauge colors appear hard-coded.
- VW/Audi (OBDeleven/VCDS): needle sweep, carbon background, oil temp on the dash, digital speed and more.
- BMW/MINI/Supra (BimmerCode): digital speed readout, cluster display options and even alternate cluster designs on some models.
- Jeep/Ram/Dodge: cluster pages and features via AlfaOBD or Tazer. GM, Toyota and Honda clusters are mostly dealer-locked.
- Want a fully custom layout today? Driving mode in this app is your own rearrangeable digital dash.
- Found the exact command for your car? Save it under Terminal → My codes to run it with one tap, as often as you like.
🔭 Head-up display
A windshield reflection of speed and RPM keeps your eyes up. This app has one built in.
- HUD mode mirrors the display so it reads correctly as a windshield reflection at night.
- Mount the phone flat on the dash with a non-slip pad, and set it up before you drive.
