Race ECU running issues

[Curtis]

Guvo,

It may be that you need to have the TPS re-set with the new ECU, a dealer job. They should run fine together as already said.

nfitz, the literature for the Veloce also state some other 'special' change to the suspension.

Not sure if this is just settings or different internals, it certainly feels pretty firm on mine (non-Ohlins).

Pretty certain its just Ohilns on the rear for the VELOCE not a different frame geometry or internals on the front shocks.

[Curtis]

Maybe but plenty of stuff illuding to some differences, not sure what of below (if any) is Veloce specific.

e.g.

"
Chassis
Moto Morini has equipped the Corsaro 1200 Veloce with high-level components to upgrade the performance of the twin cylinder and to provide the pleasure of a sporty ride. Essence of the chassis is the trellis frame in high-strength tubular steel by Verlicchi. The structure is extremely solid and combines all the stiffness required to harness the power of the engine

The function of the frame is aided by top-notch suspensions which are even more sophisticated in this sport version. At front is a powerful Marzocchi Magnum with 50 mm diameter legs with precise customisation of the setting in compression and rebound thanks to a double adjustment: the adjuster on the plug for the hydraulic damping of the rebound is complemented by an adjuster for the hydraulic damping of the compression placed at the foot of the fork. The positioning of the scraper on the bushes improves the hold of the cartridge, the hard anodized internal rod in ergal makes sliding more efficient and assures a greater resistance to wear. The longer counterspring intensifies the thrill when pullin out of a curve at high speed and guarantees better stability at the front. On the whole, the visual solidity is echoed in a solid and even ride, with the bike ready to conform to the slightest unevenness on the road and to bear the thrust of deceleration in the most race-inspired breakaways"

and

"Quickly available ,the all-singing all-dancing Corsaro Veloce £9999otr Standard equipment includes Termignoni silencers and an alternative "for track use only [!]" fuelling map. Very special suspension both ends, Ohlins, radial brakes rearset pedals in Ergal, and a mean looking paint scheme add to the fun."

Its brembo radial brake and clutch m/c
ohlins rear
front forks have nitraded coatings and internals to a higher spec
rearsets
termi cans and race ecu
frame is suppose to be slightly changed according to the factory blurb

Think thats it.

I'm going to have mine on a dyno when its run in again

I was at a place where they ran 2 on a dyno, one with termi cans (baffles out)and race ecu, the other with std cans and race ecu..... the de-baffled one made 7bhp more.

I just like the noise though

does the bike sound better with the de-cat?
is the pipework lighter?
is there much change to power? if so where?
is it better on fuel?

been thinking of saving some pennies for one........

i'd put 50p on the bike giving better mpg with a decat and powercommander with a decent map.

I've just got all the extras through as part of the deal when I brought the bike, black and carbon now but i'm not 100% sure I'm liking it.

[nfitz]

Curtis - As i said .... the spec on the exhaust sytem is identical except the termi slip ons (no power gain just sound) race ECU to bolt on, Ergal (lighter weight) foot peg castings, chassis frame and geometry is identical, and std CORSAO has both rebound and compressin damping on the same 50mm forks, but 2009 VELOCE seems to have gained an additinal internal preload spring, and a radial front brake cyliner to go with the clutch item.

Both Bikes are excellent ..... and beyond the vast majority of riders capabilities.

[Curtis]

Agreed

I was just referring to the suspension differences which were a bit vague on the literature. I have a pre-Ohlins Veloce and the literature did also refer to some suspension sportiness improvements without really detailling what was different.

Both great bikes as you say.

[franky]

the pre 08 veloce had an "up-rated" sachs shock.

changes for the 08 I think were the radial m/c, ohlins rear,ecu and all the other bits you can get done ie engine covers etc.

[Guvo]

Curtis:I think you may be correct with the ECU issues on my bike .The dealers in Australia are still getting used to the new Moto Morini bikes . I have been told by the mechanic to return the bike to them to re-tune.It was running alright for a while then started stalling at low revs pulling up to stop at traffic lights? Bad fueling or mapping errors from out of thin air?I do not know. Now the engine is surging and generally running ruff,popping and sometimes backfiring. Also stalling a lot while warming up to the standard operating temperature of 65 degrees.I have the standard ECU installed with the baffles out.The fuel I use is 98 Ron,manufactured by reputable brands recommended by the dealer hear in Australia. Hopefully they have the expertize to overcome this vexing situation.I don,t want to have to trade it in for a 1078 MV Butale,never been keen on inline fours power characteristics and lack of charisma.

[twisty]

just looking through these old postings.

From what i can gather the standard cans can be used with a full decat and the race ecu (no lamba working) and although the power ouput is not as good in terms of bhp , by removing the cat its better than stock.

Am i missing something or are the standard cans too restrictive to use with the race ecu

Hi Guys.

Just finished fitting the Termignoni front pipes and what a pain it was. you need to remove the rear shock to remove and then fit the new rear manifold/downpipe if any of you are going to do this I'd reccommend removing the whole swing arm and fit the mid pipe at the same time. I fitted the back pipe replaced the shck etc then found the middle section hit the engine and had to remove it all again. Ive been running my veloce with the race ECU and open cans no problem and had 128 bhp at the back wheel when dyno'd. I'm going to fit a PCIII in the next couple of weeks and have it custom mapped and I'll post the results I have used the bike a few times on the standard race map with the termi full system and it runs fine feels a bit crisper too so I'm hoping the map will really smooth things out the new dyno run will show any improvements which I will post.

CAT fre is the best bhp per £ as it liberates 8-12bhp at the wheel. BUT a standard ECU is no-longer able to cope as it is expecting correct data from the lambda probe as it works in an "open-loop". So you need to flash the ECU and put on it a "closed loop" map such as the "termi race"map which ignores the Lambda. In doing this all TPS vol drops need re-zeroing.Cheers Nigel

Bit confused here guys...given that reference to open & closed loop is reversed in the above post, does this mean that the standard ECU runs closed loop all the time...? If this is the case then fitting a PCIII to a standard setup would seem to be a waste of time.

Was thinking of fitting a PCIII to my bike which has the decat but everything else standard.

Would i be better re fitting the cat or will a dyno run and remap sort the fuelling out...

Does anyone know if the std lamda sensor is a narrow or wideband unit....??

[franky]

My old bike had a full Termi system, yes its a real pain to fit. I took the swingarm out.

Its now making 136bhp at the wheel and about 15bhp more in the midrange. when mapped it was making more torque than a current BSB superstock bike at half the revs.

The new owner who sometimes lurks on here is a happy man!
