aftermarket exhaust question - Ducati.ms

orion8419 · Feb 17th, 2010, 9:27 pm

im quite confused on how to go about and aftermarket fuel programmer with this bike. on my race bike i just have a pc3 and that seems to do the job just fine. now i have been told that i have to have a pc3 and a dp ecu by power commander. i have also been told just to run a dp ecu but i cant seem to find anywhere that just sells that item without the termi exhaust. my other option is the nemesis.

so im looking at the sc project exhaust. this bike will be a street only but see a small amount of track time. if i go with a full do need to get a new ecu or will i be ok with the stock one? same question with a slipon. if i need a new ecu what option would you go with.

thanks, orion

The DP ECU's are designed to work with a very specific set of modifications.

The DP ECU's are specialized, each assumes you have made a specific set of changes. For example the termi full system assumes you removed the cat, opened up the airbox lid and added the termi slip on exhaust. The fuel curves are set based on those assumptions, deviation from that set of standards results in less than ideal fueling.

The cam and the slip on both work the same way, but they are fueled differently. There is a thread on here that explains that exact nature of each of the changes as far as fuel added and what has been removed from the system (exhaust servo and 02 sensor).

If your going to do a slip on do yourself a favor and change the airbox lid while your at it. If you do this the slip on ecu will work just fine.

You could also add a PC3 or PCV to that to custom tune the set-up on a dyno, but you can't use either of the two with a DP ecu as the factory ECU will not allow changes from a piggy back controller below a specific throttle threshold.

Nemsis is a great ECU, I ended up going in that direction, but they are rather pricey and really do far more than you require. One other option is to find one on the internet from someone who has bought the cams and the exhaust, but doesnt need both ecu's.

There are also several companies that can reflash your stock ecu to work like one of the performance ecu's. You could either stick with just the slip on ecu or add the PC to it and fine tune from there.

ok so if i get a full i should look for someone selling a termi full race ecu and if i get a slipon i should look for the termi slipon ecu? i think thats the route i will end up going. if i get the stock reflashed i will still have a light from the servo right? also whats the air box mod

You take a hole saw and drill out the circular portion above the air filter. The Ducati Performance airbox lid is nothing more than that. Some, like myself, drill a corresponding hole in the bottom of the box at the bottom of the filter so you can suck from both ends.

Probably the only free mod to this bike.

If you do some searching on here, there are some photos of the work done.

When the ECU is flashed you can have the servo light and the O2 sensor disabled. If I were to do it again I would have the stock ECU flashed, disable the servo and o2 sensor. Have it flashed with the termi slip on fuel map, then use a PCV to tune each of your cylinders individually.

My understanding was that the DP ecus permitted adjustment at all throttle positions... is buggs right about what he wrote?

Secondly, I was going down the DP lid route... but the ducshop velocity stacks & pod filters are where it's at. There are a couple of intake threads on the first page of the hyper forum you should read.

I've got a DP lid if you want it... not a big deal to make one. 44 mm diameter hole in the stock lid and there ya go, if my memory serves.

The stock ECU does not allow fuel adjustment below roughly 20%, all of the others will work with a piggy back fuel controller, but cannot themselves be adjusted. They can be trimmed, but thats not what your looking for.

I picked up 8 hp by having the bike tuned per cylinder (dnyo before and after)
