Dyno'd my S4R, me happy!

[Josh_357]

Hey guys, just thougt I'd share my results of the tune I just had done on my 06 S4R. Specs are, 2006 S4R with 5,000 miles, came with a box of goodies that I put on including Termi slip-on's cut down, Termi collector pipes, and DP filter and lid. The DP ECU was no good, so I got a power commander USB and had a full tune done at the local shop. They use tuning link there which tunes the whole map at all the throttle positions available. Run's real smooth now.

Strapping in.


First map shows before and after. I think you can figure out which was before, it had just a generic map.


This graph shows the progression of the tune, we started with the exhaust sensor in the rear cyl pipe, which gave us a base tune, the lighter lines. Then we moved to the front cyl and remapped again using the advanced feature to essentially optimize the individual cylinders. The advanced tune is the dark line notice the improvement up top.



I'm a happy camper

What do you mean the DP ECU was 'no good'? Was it nonfunctional or something? Wierd.

Also, just ~115HP from a 996 Desmoquattro? Shouldn't there be more power there? Stock spec is 117HP @ 8750, 73lb/ft @ 7000. Seems that with a DP ECU + PCIII there would be more, but I may be full of shit.

Does look like a nice improvement between the two however.

sure that not 117 stock at the crank
because pretty certain that is at the wheel on his chart.

I would wager the original 117 is at the crank like most factory specs. 108 wheel is somewhere around 120's crank, 10% loss would give 121 at the crank. No clue though what kind of losses ducati motors have. What I meant by the DP ECU being no good was it's fried. It wouldn't read throttle position. Had the VDST hooked up and it would not change TP, well it also wouldn't run. So I kept the stock ecu. I bought the bike used from our local duc dealer, and the ECU was in a box of parts.

Ahhh, forgot about crank vs. wheel

Some nasty jaggies in the original run lines... I bet it feels a lot better especially from 4.5 to 8 k

[Josh_357]

Much smoother now. Excited to get it on track now.

Very nice smooth curve

Those hp numbers are spot on for wheel hp from the 996 mill in the monster too.  For reference I did a dyno day a while back and a 998 with full exhaust, tune, airbox etc put down 115hp.

i just did the same thing yesterday!  best money i have EVER spent on my bike . . . i can't believe the difference!!!
