1The engine
The type matters: a two-stroke fires every cylinder every turn, so its rpm is measured differently.
2The 5×5 holds
Each box wants one recording of the engine held steady at that rpm, about 15 seconds. Drop the file on the box or press it to choose one. Videos work.
3Extras
Drop start, shutdown, jake, horn and air-brake recordings here
4Save to the SD card
- Put the truck's SD card in this computer.
- Press Save to SD card and pick the card (the top of it, not a folder inside).
- Put the card back in the truck and power up. It plays your new pack.
A pack already on the card is kept as a backup (packs/rclc_backup_...), so you can always go back. Works in Chrome or Edge.
