Thank you again for taking the time to write about your experience with Carbyte and giving us specific and actionable feedback. As promised, here are the answers to your questions and our plans for addressing the issues:
QR code in the Quick Start Guide not working for Android
Fixed. The same QR code is supposed to automatically take you to the correct app store (Google Play or Apple) based on the phone’s operating system (Android or iOS). There was a problem with the link that we fixed this afternoon. When you get a chance, please try scanning the QR code again and let me know what happens.
Hard downshift
When Carbyte disables DFM, the engine and transmission ECUs needs some time to learn how to operate under the new conditions. The duration of the relearn process varies from vehicle to vehicle and also depends on the type of driving. To speed up the learning process, strive for a good mix of speeds and rates of acceleration/deceleration. Once the relearn process is complete, shifting should become smooth again.
Carbyte fails to sync
This problem is likely caused by connecting to the Carbyte device from the app before it had a chance to sync with the truck. Plug in Carbyte, start the engine, and let the device sync with the vehicle before trying to connect to it from the app.
“This vehicle is not compatible with Carbyte” error message
There’s an error in the code logic. We will get it fixed in the next app update.
Diagnostics & Live Parameter monitoring
Carbyte app can read and clear DTCs, but does not yet support live parameter monitoring in the app. However, you can use the OBDLink app to monitor OBDII parameters. The next OBDLink app update will have Carbyte in the Connection Wizard.
Dealer warranty
Carbyte does not make any changes to the ECU software, and everything reverts back to default once you unplug it. It does not impact factory warranty. However, we recommend unplugging Carbyte before taking it to the dealer.
Indicator LED operation and meaning
At present, this is the meaning of the different LED states:
Status (green)
- OFF: no power at the OBD connector (check fuse)
- ON: power on, syncing with the vehicle
- Slow blink: synced with the vehicle
- Fast blink: sync error
OBD
- Flashes to indicate OBD activity
LNK
- Fast blink: pairing mode (discoverable by app)
- Slow blink: paired, waiting for connection from the app
- ON: connected
- ON, blinking OFF: exchanging messages with the app
We plan on changing the meaning of the LED flashing patterns to make them more intuitive. I will post an update when it happens.
