They are a custom fuel mapping chip that fits in the Gen1 ecu.
The Gen2 has a very different ecu with two fuel maps ready programmed in.Map 1 for standard cans and Map 2 for race cans.It can only be accessed by an official Aprilia dealers Axone meter.
Gabro is a very clever fella and can custom tune your Gen 2 ecu if you need.It would involve removing the ecu from the bike and sending it to Italy for re-flashing.
