    Talking RSV4 RACE map

    I also just had my ECU updated with the Akro Race map and have noticed a good bit of difference. Especially in the bottom end grunt. Its just sick. I can even tell a difference in the sound it makes. It just sounds meaner now. I will have full dyno details soon. So far I installed a Bazzaz and got 144hp with their own map. Then Curt Jordan of Jordan Engineering tuned my Bazzaz to make 149hp and then 156hp but my bike was getting 18 MPG on the highway!!! I have a long trip to work so this was no good for me. I since have removed the Bazzaz Fi-TC with AFM and bar switch and asking $500 for the whole setup if anyone is looking for one. Then Curt Jordan had an old friend that used to make race pipes for Muzzy build me a 1lb race pipe for the RSV4. Now with this new lightweight race pipe its CRAZY loud and only good for race tracks IMO but the bike then dyno'ed at 156hp on the bikes STOCK map. I now have the slip-on Akro, stock pipe and 1lb race pipe with the Race Map installed and hoping to get a new dyno run mid next week. I can't wait to see what the Race map difference is. I'm guessing like 162hp or so.
    So if anyone wants the full Bazzaz Fi-Tc feel free to hit me up at 210-771-6675. I also have a short lil GPR race pipe for sale as well. Its the dual shotgun looking one. I used it a few times but its just too loud for my neighborhood. I paid $450 for it but Ill sell it for $200!

    going backwards

    If you live near Monterey, you have to consider putting the stock pipe back on if you want to track at Laguna with it's 92db limit so...

    if you have an Akra slip-on and ECU derestricted, it sounds like either you buy a stock ECU to use with the stock pipe or forget Laguna

    If there's a different way around this, let me know. I already bought the Akra slip-on.

    Does the race ecu work with any after market slip-on? I ask because I will be taking delivery of a Tuono V4 next month and don't like the look of the Akra or Leo slip-ons and am considering a Werkes slip-on as it is much shorter and I prefer this look and I love the sound as well.
    I must say that I am most disappointed with Aprilia for forcing us to pony up a stack of cash to buy a race ecu to run an after market slip-on. I don't mind paying the dealer a reasonable amount to reflash my ecu but having to buy a race ecu to run an after market slip-on is tantamount to extortion IMO. I hate being extorted! Just my 2 cents.

    Yes the Race ECU is specific to after market slip ons.

    How does that work? The stock pipe is homologated at more than 92db. I'm pretty sure the badge on the headstock says 102/105db.

    There's a track close to where I live that's really strict on noise and a lot of the modern road legal bikes in stock form don't pass their noise restrictions.

    It's not just Aprilia but Ducati too. Luckily we aren't stuck with the OEM race ECU with the Ducati (The MV too) because of the fine folks at Microtec. http://www.microtec.cc/cms/en/compon...ent/article/18

    As for the noise restriction that's why I went with the GP2 exhaust. With the GP2 you can buy and install different size baffles for both the link pipe and Can to quiet it down............. or not, depending on the track and or your local LEO.

    Good FYI from Amauri about retaining unlock codes for ECU.

    There you go!! thats what i am saying from the start!! Just put a slip on and you are good to go!! No other stuff needed!! If you want more HP and more low-mid-end etc.etc.(Stuff that are gonna really make a difference) then go buy a full titanium exhaust.If you are gonna do something...do it right!!!

    Ed / AF1Racing: I just recently ordered that acra slip-on like the described above from you to my new RSV4. I plan to do the change myself. But as I am not the typical mechanics, I wonder wether the job to get hold of the ECU s/n is a difficult one. I understand the ECU is placed under the tank. Is it difficult to raise the tank to get the number, or is it simply to unbolt and lift. (My workshop who will service and du the unlock is some 100km away...Please advice on procedure /tips and hints, or if you reccomend to get the bike down to my mechanics...
