By purchasing this product you declare yourself competent to make it work.

You can choose 3 engine operating modes: Standard, Racing and Competition.

The last 2 are intended for another exhaust and another air filter.

The speed limit is not modifiable.

Warning :

- Some smartphones cannot connect to this box. In our experience, the simpler the phone, the more likely it is to work.

Check that the application has access to the location of the phone, otherwise no BT communication possible.

- With some EFI Skyteam units, the mode chosen is not kept in memory, so the unit must be considered as additional and must be left in place for driving. In the event of the ignition being cut off, the comfort mode (original) is reset. This problem comes from the ECU box and not from this communication box.

- This type of article requires capacities to handle a smartphone such as: installation of an application, changes of BT authorizations, manipulation of the smartphone itself, etc ... You declare that you have these capacities when purchasing (see our conditions of sale).

You will find 2 versions of the application 1 and 2, the 1 is suitable for android smartphones version 7 and before; version 2 and for android 8.0 and later.

You will find on our blog a summary manual of the ROJO program for this Zhenhua Skyteam bluetooth injection unit

Here is the manual for version 2

- All genuine Rojo ECU are limited at 11000 rpm
- These Rojo ECU has 3 curves in it with different power but always with the rpm limit
- For changing the curves you need the Bluetooth box and an Android smartphone
- So : to win speed you need to change the curve AND the sprocket ratio

questions Dimitris Avgoustinos  on 2021-11-09

Skyteam S125-8 / mod. 2021 EU4 EFI. I already have a freeflow exhaust. I will need a "racing air filter" could you propose the proper one? Regarding the transmission, I think I should go for a smaller pinion could you propose the proper one? Could you please confirm that with the above-mentioned alterations I will take full advantage of "racing" mode? Many thanks in advance Dimitris
