Dove into tuning options for the Aprilia - jesus fuck the Aprilia forum is as disorganized as this place. 800 tuning threads with 15 pages of comments discussing options across all of the variants of V4's
Basically boiled down to the following:
Gabro tune from Italy - no longer will program customer ECU's sent to him due to red tape laws - Will allow you to buy a preprogrammed ECU from him to ship over ($800-ish)
Aprilia Race tune -
installed - roughly $250 - doesn't void warranty (supposedly)
Aprilia Race ECU - exact same as above, but allows you to have a spare ECU
Aprilia Race tune loaded via pirated/hacked software - Software and tune is free aside from buying the appropriate $30 cable - not the most user friendly, but certainly the cheapest - will absolutely void warranty if the engine
Open Flash Tablet - Tablet preloaded with tunes - allows user reprogramming with some diagnostic functions ($800) includes free tunes as they become available/
The Gabro tunes are supposedly the best in terms of rideability and powah. Race tune seems pretty good as well, but could be better - it's somewhat conservative. OFT delivers the most powah, but seems like throttle transitions are a bit unrefined.
