Plug in. Pair. Drive.
Bluetooth OBD-II or native CAN where supported. GEARI reads RPM, vehicle speed, throttle, and engine load. No dealer tool.

Every shift.
Scored.
GEARI plugs into the vehicle computer and records every gear change. Smooth shifts, clean lane changes, and measured braking earn points. Build an independent safe-driving rating that rideshare platforms do not own.

Connected to the car
The stick-shift computer
your phone never had.
Most telematics apps treat a clutch like an automatic. GEARI infers gear from the speed–RPM ratio, times the shift window, and scores how cleanly you complete it.
02
Every shift is a record
Up, down, skip-shift, or into reverse. Each event stores gear in, gear out, RPM band, jerk, and a smoothness grade.
03
Points for control
Smooth clutch work, signaled lane changes, and progressive braking add points. Dumping the clutch or stabbing the pedal costs them.

GEARI does not need a US-only OBD-II stack. The 16-pin port under the dash is the same in Brazil, Japan, India, and Thailand. The law has another name — OBDBr, EOBD, JOBD, KOBD, China 6, BS-VI. The app reads RPM, speed, and load from that port, then infers every gear.
01
Find the port
16-pin socket within reach of the driver — usually under the dash, driver side. Same SAE J1962 / ISO 15031-3 shape in every first-wave market.
02
Plug a BLE adapter
Bluetooth Low Energy dongle. iPhone needs BLE or MFi. Android accepts BLE or Classic. Cheap Classic clones will not pair on iOS.
03
Handshake
GEARI auto-detects CAN, KWP2000, or K-line. A ten-second smoke test asks for RPM and speed. Both streaming means ECU mode is on.
04
Fallback
No live PIDs? Phone GPS + IMU still scores lane and brake. The public rating shows a sensor badge, not a fake ECU score.
What the adapter talks to
One connector. Regional names.
Pins 6 and 14 carry CAN on most 2008+ / OBDBr-2 / China 6 / BS-VI cars. Older Asia and Europe use the K-line on pin 7. GEARI only needs legislated Mode 01 PIDs — not dealer coding.
Highlighted: 6 CAN-H · 7 K-line · 14 CAN-L. Pin 16 is battery. Gear is inferred from speed ÷ RPM. Clutch position is almost never on this port.
SA
South America
Brazil OBDBr-2 / 2+ (ISO 15031, flex-fuel). Argentina and Chile follow EOBD-style ports on later cars. Mexico ~2007. Probe older Andean fleets — the hole can exist without live data.
FE
Far East
JOBD (Japan), KOBD (Korea), GB 18352 China 6, India BS-VI, Thailand and Philippines Euro 4 EOBD. JDM cars can be picky with clone dongles. Export models are usually easier.
PID
What we read
RPM, vehicle speed, throttle, calculated load, MAP or MAF. Enough to time a shift and grade jerk. Not fuel trim — ethanol flex cars swing those numbers.
HW
Adapter allow-list
Vgate iCar Pro BLE, Veepeak BLE+, OBDLink MX+ / CX. Avoid unlabeled ELM “v2.1” clones on Mercado Libre, Shopee, and Lazada for daily scoring.

Market matrix
| Market | Local system | Typical ECU year | Notes for GEARI |
|---|---|---|---|
| Brazil | OBDBr-1 / 2 / 2+ | 2007 petrol · 2010 solid · diesel ~2015 | Flex-fuel. Use RPM and speed, not fuel trim. |
| Argentina | EOBD-style | 2008 domestic · 2009 imports | Same 16-pin. Safety homologation ≠ OBD profile. |
| Chile | EOBD / Euro 6c path | 2013 diesel · 2014 petrol | Later cars are the reliable ECU set. |
| Mexico | OBD-II / EOBD mix | ~2007 | US and EU platforms both common. |
| Peru / Colombia | Import-led | Varies | Port present on many imports. Smoke-test before scoring. |
| Japan | JOBD | 2003 basic · 2008 domestic | JDM may need a better adapter than export twins. |
| South Korea | KOBD | 2005–06 · full ~2010 | Gasoline coverage is strong. |
| China | GB 18352 China 5 / 6 | 2010 petrol · 2020 China 6 | Standard scan-tool PIDs on China 6. |
| India | BS-VI OBD I / II | 2017 tools · 2020 / 2023 / 2025 stages | Hindi / Urdu / Punjabi markets. CAN on new cars. |
| Thailand | TIS + EOBD | Euro 4 with EOBD from 2012 | Euro 3 wave can have a plug and no live PIDs. |
| Philippines | Euro 4 EOBD | ~2016–18 | Consumer BLE dongles widely sold. |
A 16-pin hole is not a promise. Newest 2020s platforms may use CAN-FD or DoIP — v1 stays on classic CAN / K-line and phone fallback. EVs are out of scope.
Points system
A score you can explain.
Not a black-box insurance grade. Drivers see why a trip paid or lost points — useful for self-coaching and for rideshare profiles.
| Event | Signals | Points |
|---|---|---|
| Smooth upshift | RPM in band, low jerk, no lurch | +8 to +15 |
| Rev-matched downshift | Blip detected, RPM lands on ratio | +12 to +20 |
| Signaled lane change | Heading + IMU, no abrupt yaw | +4 to +8 |
| Progressive braking | Decel curve, no panic spike | +5 to +12 |
| Hard brake / clutch dump | Jerk above threshold | −10 to −25 |
| Arrive inside safe window | ETA vs. destination time you set | +10 bonus |
Before you start
Add where you are going.
Add when you must arrive — safely.
Set work or any destination and a desired arrival. GEARI builds a time-to-reach that assumes legal speeds and calm inputs — not the fastest possible route. The trip score includes whether you kept that promise.
Safe arrival window
Leave by 07:58 · arrive 08:24–08:30
Buffer built in for lights, grade, and measured shifting. Aggressive routing is off by default.
