Engine light on SIP Vespa tachometer

Hello fellow Vespa riders,

After installing the Malossi Force Master 2.1 on a Vespa GTS 300 of 2014, with the engine perfectly working, note the engine light comes on.
I was told that it could just be a false alarm and that the units could be reset.
Anyone had the same experience and can suggest a fix?

Thank you,

Max
