I displayed all the details of the Rexxer ECU flash of course. But fuel module cannot affect the driveability range below 4k rpm. An ECU flash can. Dave works for Ducati and develops these maps. They won't damage your bike. It would be the same as the ecu flash from november for the fuel map update, but even more intense without the emmision restrictions. I plan on having it done because the bike is a whole different animal with the new update. I can't imagine what it is going to be like with the bikes full potential.
I remember reading someones post earlier about how he was having stalls. The dealer took the bike back, removed the exhaust valve, carbon canister, and fixed wiring ground, then adjusted ECU... They removed the restrictions and did an adjusted flash! No different than Rexxer. I would highly recommend you look into them. If it were any other company I would not trust them. But Dave WORKS at the Ducati dealer in Yorktown, VA and develops tunes for Ducati's and other bikes. If it were anyone else that didn't have experience or work for them I wouldn't trust them. I plan to have mine flashed probably next month so long as my dealer allows it. Cheers!
