Transform your Android device into a personalized display and monitoring system. DashCommand empowers you to oversee and log engine and vehicle performance, fuel efficiency, and promptly read and erase troublesome check engine lights, all through the user-friendly DashCommand app.

This application also includes a professional skidpad that showcases lateral and acceleration/braking Gs with minimum and maximum indicators. Additionally, it features a race track that visually represents your location, along with acceleration and braking while you navigate through laps. An inclinometer is included to display rolling angle and vehicle pitch for off-road use, plus the capability to data log, record, and replay log files that depict OBD-II and acceleration data.

DashCommand has earned recognition as the 1st runner-up for best mobile electronics product at the SEMA Show and is a four-time recipient of the SEMA Global Media Award!

IMPORTANT: To connect with the vehicle, DashCommand requires a compatible third-party hardware interface, which must be purchased separately.

DashCommand is compatible with all OBD-II and EOBD compliant vehicles available globally. It's crucial to confirm your vehicle's OBD-II/EOBD compliance before making a purchase! Not all OBD-II compliant vehicles will support every parameter described.

Manufacturer-specific data is available for certain vehicles through in-app purchases.

Compatible OBD-II Hardware includes:

- Auto Meter DashLink

- PLX Kiwi 3 and Kiwi 4

- OBDLink MX+

- ELM compatible WiFi

- GoPoint BT1

Your Pocket-Sized Race Engineer: Where Data Becomes Driving Instinct

Forget clunky OBD readers and vague mechanic guesses—DashCommand transforms your commute into a masterclass in vehicle literacy, making real-time performance feel like a high-stakes racing sim. As someone who’s tracked lap times for years, I was stunned by its ability to turn abstract parameters into visceral, actionable insights.

Connecting via my PLX Kiwi 3 dongle, the app didn’t just read RPMs or coolant temps—it painted a live G-meter heatmap on corners I’ve driven a thousand times, revealing exactly where I was bleeding speed with timid braking. The genius lies in context: watching fuel trims spike while logging lateral Gs on that off-camber exit showed me how suspension load affected air/fuel ratios—a correlation no standalone scanner could visualize.

But the true revelation? The racetrack replay feature. After a backroad blast, replaying my route with throttle/brake inputs overlaid on the map felt like debriefing with an F1 engineer. Seeing exactly where I lifted prematurely (costing 0.3 seconds) or overcooked a shift was transformative.

Even mundane commutes became data goldmines: live MPG pulse graphs taught me to pulse-and-glide efficiently, boosting efficiency by 12%. For off-roaders, the inclinometer’s pitch/roll warnings prevented a sketchy trail tip-over.

Yes, manufacturer-specific codes require in-app unlocks ($12 for my VW group), but the core OBD-II suite alone justifies this as essential kit. This isn’t diagnostics—it’s vehicle telemetry that turns drivers into technicians.

Quick FAQ:

Q: How accurate are the G-meter and track mapping?

A: Shockingly precise when paired with premium hardware (OBDLink MX+/Kiwi 4 recommended). GPS drift is minimal under open sky; inertial sensors sample at 100Hz. Not MoTeC-level, but rivaling $500 standalone units. Avoid cheap ELM clones—latency ruins dynamics.

Q: Can it really replace professional diagnostics?

A: For real-time monitoring and basic codes, yes. For deep ECU programming or manufacturer-specific adaptations (e.g., resetting Tesla modules), still see a pro. Its strength is understanding behavior, not rewriting it.

Q: Is the "skidpad" just a gimmick?

A: Absolutely not. It logs sustained lateral Gs to calculate cornering balance. Seeing 0.89G peak on summer tires versus 0.78G on winters (same corner) objectively proves grip limits—priceless for track day prep or tire testing.

Q: Does logging drain phone battery?

A: With screen off, ~8-10% per hour on modern phones (tested on Pixel 7). Use a car charger during extended sessions. Export logs as CSV/PDF post-drive for analysis.

Q: Are in-app purchases predatory?

A: Transparent and niche. Manufacturer packs (5−20) unlock brand-specific sensors (e.g., BMW turbo pressure, Porsche throttle maps). Core OBD-II functions require no extras. Buy only if you need granular OEM data.
