DP cans +

[celt]

hello people.

i bought DP cans by remus for my 2003 620ie. when i went to my dealer he spotted them and said i hope you got the ecu with that.
i asked stuart at spareshack and he said this was bollocks as the 620ie ecu will compansate for the change.
i now want to pop a k&n air filter in and before i go to my dealer again can you bods out there tell me if having the DP cans and open K&N air filter will my ECU still be able to cope.

i hope so cause i have seen the cost of the ecu's and power commanders and i cant afford that!!!!!!!!!!!

thanks
UKMOC to the rescue

It maybe that the leaness is within the working limits of the motor.

Some people have suggested that Ducatis run rich and that the end can brings them closer to an ideal mixture. I find this hard to believe given modern emissions regulations.

I am always curious when people say the ECU compensate for this change in mixture.

How will it know?

Which sensor will tell it that the engine is running lean?

Unfortunately modern bike fuel injection systems are very simple compared to car ones. In a car system the lamda sensor will detect a lean/rich mixture and the ECU will adjust the mixture to compensate. As far as I know Ducatis do not have Lamda sensors.

Sorry I cant answer your question, its one I'm curious about myself. Stuart is a knowledgable guy who sells a lot of pipes and I'm sure if there was a problem he'd say so.

I'd just like to know how the ECU knows to compensate, so if anyone knows, please tell.

BTW, I would have thought that even if the ECU could handle a pipe change, a change of filter would take it beyond the standard mapping, that way Ducati get to sell shiny new Ducati Performance chips.

looks like i may have to bit the bullet this time. do you know which will be the cheapest ducati performance chip or the power commander III?

has anyone done this to a 620ie? if so can u recommend it?

cheers crust

dont know about the ie s but the 600 900 runs a bit rich, the k n I have replaces the top of the box and the old filter, it just clips on the top, they are 30-40 quid. may be worth while trying just first then investing in an ecu if you feel you need it or if a dyno run suggests one would help.

The way I can imagine the ecu will compensate is by detecting the engine running hot - which is a symptom of a lean mixture - so the ECU will richen the mixture. That's the theory...

However, this assumes the ECU can richen the mixture by a sufficient amount, but I'm sure it must work within limits and so may not be able to provide enough adjustment.

I had termis, air filter and open airbox lid installed on my M1000 from new and the dealer (ProTwins) were most insistent that a new fuel map be uploaded (they didn't charge me for it).

A ducati dealer should be able to upload an appropriate fuel map into your existing ECO - for a modest fee I expect, but a lot less than a new ECU.

I fitted DP (remus) cans and DP open air filter on my 800Sie.
The Ducati dealer that supplied them said that if it didnt run properly they would have a look at the chip setup, but if it ran ok there would be no need to do anything and they would just have a look at the emissions when it went in for a service. In fact two different Ducati dealers advised that there would be no need to buy a new chip because the standard chip could be re-mapped or contained sufficient maps from standard, thats why Ducati no longer supply a replacement chip with the DP Performance exhaust kit.

If I were you I would stick em on and see what happens, if it runs badly get a dealer to look at it.

Since I fitted mine the fuel consumption has improved to nearer 50mpg but thats probably cos I now twist the throttle less to go at the same speed.

I have a 620Sie and a couple of months ago got my dealer to fit some high level DP (Remus) cans and the DP open air box/filter. They told me that they would do the fuel mapping as a matter of course when they change pipes and filter so that it is running spot on. There was never any mention of replacing ECU!

[A Yerbury]

not an expert on these thing but its just a case of attaching to a pc/laptop and using a bit of software to change it...I thought!?

I agree - as far as I know none of the monsters have an oxygen sensor in the exhaust system so the ECU cannot possibly compensate for different exhaust systems. I think that a lot of people have been mislead by ignorant dealers and/or misunderstandings about what the ECU can actually do.

It is perfectly possible that no adjusts need to be made for a particular set of silencers BUT this is by no means guaranteed!!!

The carbed bikes appear to be set up rich from the factory - since fitting freer flowing cans the mixture has got closer to optimum bbut this is based on spark plug colour not exhaust gases.

I have an 02 900ie and Remus DP Cans and Open Air Box, and had mucho problemo with the running of the bike.

I spent a long time looking into it and arguing with dealers etc and got to the bottom of it all.

from 02 at least onward the ECU's are not part of the kit as the standard chip allows for minor changes to be made (what they are exactly I can;t remember) and this allows for flat spots etc to be ironed out.

It does not allow for remapping like a power commander but eventually I got the bike set up well so a PC was not needed.

Get it set up by someone you trust. Dave Woods managed in one day, what my dealer couldn't do in weeks!

Worth while getting it done as it'll save you £300 for the PC!

as always the UKMOC bods come through.

cheers i will buy the filter and fit.
if it runs like poo i'll get it tweeked.

hope it goes good with both as with just cans it doesnt seem quite right. seems to sound like it revs higher at same speed than before and until its warmed up it sort of has lag when i give throttle wellie.

i will post my findings later in the year :D

[A Yerbury]

the k n s go for good prices on ebay, avoid the pod style ones though, as tempting as getting rid of the whole bulky airbox seems I have heard bad reports.

[celt]

no prob i have also heard that the pods are a pain.

I've got Remus Grand Prix cans on my 900ssie and it runs beautifully with the standard ECU ('98 bike).
I also have a performance filter and airbox "lid" (standard lid mostly cut away to expose the air filter) which i fitted and didn't really feel it did much for the performance - didn't run badly, although the idle speed needed slight adjustment, didn't seem to run any better either, certainly as a road bike it made no noticable difference to speed or acceleration. The induction noise was deafening though, far louder than the exhaust from the rider's perspective when you bang the throttle open.
I took it round to my local tuning specialist (AJ Racing) and he advised that it'll run pants under acceleration if the fueling's out and be really obvious. He advised keeping an eye on the exhaust colour, and doing a plug chop if I was still worried. He also downloaded a PC map from Dynojet's site, from a similar bike set up on the dyno with open pipes, K&N filter and open airbox, and examined it. The fueling had hardly been altered from standard, a fraction more fuel added in the midrange under hard acceleration but they're underfueled there from standard to help the bike pass emmisions tests.
I ended up taking the airbox lid back off and refitting the standard, for peace of mind and because I was getting deafened by the induction noise, but keeping the performance air filter in. 5,000 miles later all seems perfectly ok, plug colour good, exhaust colour seems ok, bike pulls smoothly on acceleration.
If still in doubt, get it dynoed, that'll tell you exactly what the fueling's doing for around £25 - £30, certainly worth it for peace of mind.
