If you own a late model Ducati with oxy sensors as standard and you've
changed the exhaust and whatever else, then the chances are you've got
running problems in the low to medium speed area. You can tune these bikes
using a Power Commander - however because of the closed loop system you
wont be able to fix up this area. As you spend most of your time at less
than 30% throttle it's almost a pointless exercise.... until now.
We have found a way around this problem by fitting an exchange
ECU that's open loop through out the entire rev range eliminating the need
for an oxy sensor. In other words you disconnect and remove the oxy sensor
and plug the hole in the exhaust. The exchange ECU will now allow you to
remap the entire rev range for any given throttle using Power Commander
or any other similar device you may feel all warm and fuzzy about. We used
a Power Commander to achieve the end results as shown in these graphs
and pictures.
On the road the bike is smooth at part throttle with no hesitations,
it no longer stumbles when you're negotiating roundabouts and traffic,
and rolling the throttle on is a breeze; more power everywhere, yes, except
now it's very much easier to control and sure to put a big smile on your
face.
Please note this example is an S4RS, and as I said earlier any Ducati
with an oxy sensor will have this problem which pretty much includes every
late model bike from about 2007 onwards.

Ducati Multistrada
Ducati Multistrada. Fitted with slipon mufflers and PCIII
We made 2 maps, one with baffles in and one without baffles. As you
see the top end is good on both however, mid range has 5hp more with baffles
out. The nice thing about Power commander is that with the map selection
switch harness he can select his map with a switch on the handlebar.

My Ducati Hypermotard is not the first bike I've taken to Dave & certainly
not the last. It's been on the dyno at stock, then with mods and a re-tune
the Hyper's output has exceeded expectations. 'Dyno-ing' may be regarded
as textbook as it's becoming more frequent for larger workshops to have
a dyno nowadays... But what you can't compare is Dave's experience, genuine
care and respect for you and your bike. Without hesitating I'd recommend
a visit to Dynobike!
Cheers Bren

This poor old girl supposedly had been re-chipped to suit the pipes - this
is a classic case of why re-chipping is a waste of time. With a Power Commander
installed we had total control of fuel requirements and look at how it
totally transforms this bike. The blue line shows the improved performance.
