In any case it is advisable to use resistive spark plugs.

When the ignition system is not encrypted, any key will start the engine but limited to 2000 rpm. The
keys can only be recognised when the decoder has been correctly programmed. The procedure for
programming a new decoder requires the recognition of the "master" key as the first key to be pro-
grammed: this is particularly important as it is the only key that allows the decoder to be reset and
reprogrammed for programming the service keys.
The master and service keys must be used to code the system as follows:
- Insert the Master key, turn it to «ON» and keep this position for two seconds (lower and upper limits
1 to 3 seconds).
- Insert the service key and turn it to «ON» for 2 seconds.
- If you have copies of the key, repeat the operation with each key.
- Insert the MASTER key again and turn it to «ON» for 2 seconds.
The maximum time to change keys is 10 seconds.
A maximum of 7 service keys can be programmed at one time.
It is essential to adhere to the times and the procedure. If you do not, start again from the beginning.
Once the system has been programmed, master key transponder, decoder and control unit are strictly
matched. With this link established, it is now possible to encode new service keys, in the event of losses,
replacements, etc. Each new programming deletes the previous one so, in order to add or eliminate
keys, you must repeat the procedure using all the keys you intend to keep using.
If a service key becomes uncoded, the efficiency of the high voltage circuit shielding must be thoroughly
inspected: In any case it is advisable to use resistive spark plugs.
