- Follow Getting started (Steps 1–7) to install CarPrint, connect your OBD2 BLE adapter, and record trips on your phone.
- Complete Step 8 — turn on upload and sign in so Scott can verify your trips for the reward.
Reward rules
- Amount: $35 USD per qualifying tester.
- Cap: first five testers Scott verifies as fully qualified on the server.
- Verification: Scott confirms the five winners have uploaded more than 20 trips and 400+ total miles.
- Payment: $35 USD via Venmo, PayPal, or Amazon gift card.
- Feedback about the OBD2/CarPrint connection, MPG or the validity of other metrics, and anything confusing would be appreciated.
