pretty sure that's normal for that bike.
Nope. Not normal. Well maybe normal, but not correct.
To Zipper23: I've seen your problem before and to better explain it I contacted the Foggy guru that discovered, isolated, and solved that problem years ago. His post (info he was giving to another guy with the same problem) will follow but the short answer is...you have the wrong ECU in the bike. Contact a Dealer and get them to correct it. And you can thank Tom.
"Not sure how much help I can be; my bike's been all sorted out for some time, and my memory is suspect...
But I'll try:
If you had the single fan issue, then yes, you probably have the 2001 DP ECU installed. I don't remember exactly what the other symptoms were, but the kickstand safety also didn't work properly with that ECU--so not sure what your mechanic bypassed .
Now, I'm not sure which of my posts you have read but, I am the one who figured out that Ducati messed up on our bikes by putting 2001 ECUs in the DP kit that shipped with our 2002 bikes. So, I got them to make new DP ECUs that were configured to the 2002 harness and gauges, etc. For a while, they would give Foggy owners an updated ECU--but only if you asked (read, complained). There might be some small chance that they will still, but they probably don't have any left.
As to selling your "spare" ECU, there is a very good chance it is "married" to your bike, and that it will not work on another S4. So, if you do sell it, you should be very upfront about it probably NOT working in the new bike...
As to confirming if you do have the DP Full Exhaust ECU, the best (perhaps only) way to tell is simply take the bike up to the rev limit a couple times. I don't remember exactly, but I think the stock ECU is about 9500, the half-exhaust ECU about 10000, and the full exhaust about 10500, and SPS cams ECU 11200 (I know this one for sure ). I could be off a couple hundreds, but I know it is in my posts somewhere. And the old DP catalog had dyno graphs detailing the various redline cutouts.
But, even still, you will still have the 2001 ECU, in a 2002 bike. We knew about the fan and kickstand issue, but Ducati would never admit to any other possible differences. That said, the bikes do seem to run ok, with the "wrong" ECU.
btw, the part numbers may, or may not, be on either ECUs, and may not mean anything. Ducati Performance used a batch of old 996 ECUs, and re-programed them, and then simply stuck new stickers over the old ones for pretty much all their performance ECUs--and the stickers sometimes didn't stick too well. The DP ECU for the 54mm exhaust on the 996R I recently sold, had an underling sticker that matched my S4 DP ECU..."
