Title: ECU/TPS swap with exhaust or not Post by: BourneS4R on September 07, 2011, 09:08:23 PM So I have heard mixed things from people and technicians alike about aftermarket options. One Ducati tech suggested that any exhaust swap be done with an ECU/TPS swap.Justification: stock will not work well with aftermarket pipes and will degrade said pipes performance boost; possibly even make worse.
All of the Arrow systems I have seen for sale, slip-ons as well as full systems and on multiple web pages, state that they systems specifically do not require an ECU swap and will boost performance approx. 5-8 HP alone. I have historically sided with the latter opinion but I'd like to see what everyone else thinks.

Title: Re: ECU/TPS swap with exhaust or not Post by: uglyducky on September 08, 2011, 01:05:35 PM they run funky with no attention to fuel mapping and more open, free flowing exhaust. not terrible just not ideal. but give it a go. that's an easy fix if you don't like the combo. either buy an overpriced aftermarket ecu or get a stocker reflashed.
Title: Re: ECU/TPS swap with exhaust or not Post by: corey on September 08, 2011, 03:30:05 PM think it's going to depend on the bike. i realize now you're on an S4R, which might be more prone to "funkyness"....
From everything I've heard, the 800's (like mine) tend run just a little lean, but fine.

The rough spot between 3 and 4 grand is gone and now it pulls very cleanly and useably from 2K up. I did not mod the air filter. Bill
