    This changed at a later stage maybe?
    I do have a 2010 rsv4r, so that might be possible :p7

    Yes is possible as murph correctly pointed out,

    from 2009 Factory WSM.

    Butterfly valve in exhaust

    Function;
    It is used to reduce exhaust noise. The exhaust valve is open, when a gear is engaged, in any condition, and closed in neutral if vehicle speed is equal to 0 km/h (if speed is different from zero, the valve is open).

    Has nothing to do with engine number.

    ECU software update is what changed the operation of the EX flap valve open/close timing.

    Relax amauri...it was in reference to the exact moment when the change in operation happened...our buddy Plocky is quite knowledgeable too

    Ok,

    But like I said, it was not related not an engine serial number.
    The "exact moment" when that change happened was when the ECU got a new software update.

    Many bikes were updated during PDI with new software (std or Race), that update changed when the valve opens.
    So if you reference the engine number, it will not be a valid comparison and only add to more confusion.

    You must reference the software version number.

    lol!!
    Thanks for your vote of confidence murph, however I make no claim of omnipotence; especially when it comes to Aprilia.
    I'm just your average enthusiast with some experience & knowledge from reading & searching the forum & manuals.
    I like to help when I can; or at least point people to someone that can help like amauri with hist vast experience, knowledge of all things Aprilia & motor engineering..

    Cool that explains that then, sort of.

    Was the updated ECU software referenced to all RSV4 from the first model or did it start at a certain progression of the aPRC system?

    I'm guessing as it's just an exhaust noise thing, that it was about Euro3??

    For example if MrSlashzz took his bike to a tech & had the ECU updated to the latest available stock mapping/software compatible with his 2010 RSV4 R model ECU, would it be changed to operate the exhaust flapper with respect to throttle operation & revs like our later model bikes?

    09 -14 all get updated with the same latest release software/map, just have to disable/enable APRC and ABS to match the bike.

    For example:

    A 2010 RSV4 will be updated with the same map as a 2014, but APRC and ABS features must be disabled.
    2015 & 16 bikes get a different map, and now with the 2017 bikes it is different again.

    Cool, thanks for the reply. I'll extrapolate from that then that the 2010 flapper would behave as the later models do if MrSlashzz had his ECU updated. Yes?

    Just a quick question
    So I have fitted an Akra slip on to my 17 Tuono, and I have it booked in for a remap with my dealer.
    I have removed the cables and servo and have the engine management light on as expected till I get the race map uploaded.
    What im wondering is, as I’m riding it approx 20 miles to my dealer , will the engine management light turn into a service or urgent service warning and stop me riding the bike, or will it just be the engine management light and log a fault code that will be cleared at the map upgrade?
    Cheers
    Dirk
