In some EFI Skyteam units, the selected mode is not kept in memory. If you want the selected mode to remain active, the chip must remain with the vehicle while driving. As soon as the ignition is switched off, the ECU will reset to the default mode. This problem comes from the ECU and not from the Rojo chip.

Electronic components can no longer be exchanged or refunded.
