2004 S4R exhaust and mapping

[George S]

While researching how to adjust the TPS, I came across the following article on another Ducati forum:

"The 2002 onward ducatis have a sealed computer, meaning when u install a half system or a full system, instead of just replacing a chip(about 200 bucks) you have to replace the whole computer(650 bucks) and then you have to alter the mapping."

Is this accurate? My bike came with a full Arrow exhaust. How can I verify that my computer was replaced, if a replacement is necessary?

Also, I am in the process of replacing my steering bearings. Any recommendations with brands other than Ducati? I know Speedy Moto makes a set and they're significantly less expensive.

You can also have those ecu's reflashed.

Is your immobilizer functional?

[George S]

what is the immobilizer?

[ducpainter]

what is the immobilizer?

It's an anti theft device built in to the ecu.

It won't allow the bike to start unless there is a properly chipped key inserted into the ignition, and gauges that match what the ecu wants to see.

Is there a blinking yellow led on your gauge cluster?

Yes...

[ducpainter]

Yes...

I believe that you have either a stock or DP ecu because I think if yours was flashed the immobilizer light would not function.

How does the bike run?

[DucRS]

  With latest software immobilizer light remains after reflashing, at least that's the case with mine.

  You can also look at the ECU serial #s to see if it's stock or DP.

Does your immobilizer work?

I had read that you now have the option of disabling or not.

[DucRS]

  I havn't checked. I had the ECU reflashed then I reinstalled it  and
rode away.

How does the bike run?

Well... it runs fine, I guess. Question is, how good can it run? I bought the bike about 18 mos ago with 12K miles. Seemed to run fine, but previous owner doesn't seem to have been a real stickler for maintenance and doing everything possible to get 110% out of a bike like this. The bike even has a power commander... and after I get the throttle bodies and tps adjusted, I plan on having the bike dyno'd and making sure everything is dialed in.

Otherwise, when I push the button, it starts. And when I twist the throttle, the bike produces a deafening sound and takes me where I wanna go. 

[ducpainter]

It should be pretty strong. The 996 is a 110 ish hp motor.

How's the driveability? Is it smooth...no stuttering or flat spots?

I believe now you have a stock ecu and the PC was used to add the necessary fuel because of the system.

It's the alternative to a DP or reflashed ecu.
