CF Moto 450 MT

[Mirko1996 12 Napisano Januar 5]

Ja sam sada gledao ove sve CF motore. Realno ovaj 450MT je posle 800tke najbolji za put i da kazes eee vidi lijep predio sad cu se popeti po makadamu. Kod mene u Hercegovini kamenje ko da ides po iglama.

Mislim da je 450tka pun pogodak za takve puteve pored u odnosu na ove druge cf modele. Ja kao manji poznavalac tako gledam.

Najbolji je koji ima klirens najveći pa onda vešanje.

Slazem se @Džim Džarmušali mi koji se ne razumijemo toliko u motore gledamo po izgledu. Meni ce biti ovo prvi motor u zivotu na koji sam sjeo. A sto se tice razumjevanja dijelova jedino znam gdje je gas kocnica mjenjac kvacilo.

Ovaj model ti je super po svemu i da si zahtevniji vozač.To sa plastikama je najmanji problem ne opterećuj se nije to baš toliko bitno a i slabo u normalnom korišćenju,drugo je ozbiljan  off često.Dobro si odabrao uživaj kad stigne.

Edit: sad vidim da ti je prvi motor, drži se 450tke, ipak, sa srećom

[Mirko1996 12 Napisano Januar 5]

@Vojkan 700MT kad bi izasao ovdje sa asvalta mogu da se kladim guma bi stradala. 

To je po mom misljenju top zujalica po gradu. 

Gledao sam samo gume ove sto se dobijaju fabricki. 

[Mirko1996 12 Napisano Januar 5]

@živkedobro taj tvoj ima jos plastike na sebi kako ga vozas.

[Vojkan 192 Napisano Januar 5]

U pravu si, izvini

@Mirko1996 Šalu na stranu, nisam ja baš neki vozač, a i nije da ne pazim motor. Pao sam samo jednom sa njim, na snegu, a i krivo mi je što sam odrao plastike, planiram da sredim.

Znam za providne folije i hteo sam da ih stavim ali nisam stigao pre ture, kao ni kreš barove. Ali sve će da bude

Vrlo zanimljiv post koji mozda rjesava problem trzavog gasa

Ako je ko u mogucnosti da proba, bio bih zahvalan. Ja nisam trenutno fizicki kod motora.

Jeste probali sa kit-om za eliminaciju o2 senzora?

So here it is, simple easy fix for the fuel cut on the 450MT. I will give a bit of background on what is actually going on here for those that are interested and a link to me, to show I am not just a Snake Oil salesman.....I have been doing this for 30 odd years.

https://www.fullnoise.com.au/fullnoise-news/kiwi-technician-wins-2013-yamaha-oceania-tech-gp/

 

So the fix is simple, fully reversible and in no way will it affect the bikes performance or warranty, because it is not asking the bike or ECU to do anything that it does not normally do anyway, we are simply asking it not to do it, not just sometimes.

 

Emissions has always been a thing and more so in recent years. The 450MT has a fairly abrupt fuel cut on deceleration as most have noticed. Even with the recent update, it is still a thing.

So i got to thinking. Lets bypass it. With the gear I currently have available I managed to read the ECU mapping and data and got to studying it.

 

The 450MT has a programmed overrun fuel cut, to help with emissions. It physically shuts off the fuel injector when the throttle is completely closed and the bike is in overrun.

However, there is a Map active that comes into play under 3000 rpm or there abouts when the clutch lever is pulled in. It releases the fuel cut. 

 

Quite simply if the bike did not have this mapping, on overrun, slowing down with the fuel injector turned off, when you squeeze in the clutch lever to down shift......there is no fuel currently coming in.........you got it, the bike would simply stall out between gears down shifting, because it has no fuel to keep running as the injector is currently off. Not ideal.

 

To counter this the ECU has a clutch switch that recognises when you squeeze the clutch to down shift or coast to a stop in gear and releases the fuel cut, to keep the engine running.

 

Simple fix. Unplug the two wires going to the clutch switch on the LH perch and connect them together as per the attached photos. the ECU will now not apply the fuel cut....ever. It will simply stay on the normal map. After the mod, It took about a 30 minute ride for the long term fuel trims to fall back into place and now it is as smooth as one would like.

 

No snake oil, just an in depth understanding of engine management and many years of trying to better the system.

Enjoy everyone!!. It's a different bike.

 

The only downside as such is that now if your bike is in gear and you hit the starter it will try and start. Please pull the clutch in!.

Vrlo zanimljivo, mada nisam razumeo do kraja. Ali mogu mozda da probam sutra. Daj i te slike.

Ima li nekog iz NS i okoline ko je voljan da pokaze motor? Ne mora proba

[Skittles 4221 Napisano Nedelja u 15:57]

... ako je Beograd okolina

Mada, ako sačekaš da bude malo toplije, nađemo se na nekom delu onog nasipskog autoputa između naših gradova.

Ko odluci da proba neka to uradi na svoju odgovornost. Da ne bude da sam ja kriv ako sta ne bi bilo dobro.

 

Ja cu licno probati kad budem kuci.

Kako jednostavno zvuči i izgleda ovo riješenje, nestrpljivo čekam Feedback.

Inace u komentarima na FB postu ljudi govore da ovo radi.

 

Poslije premostanja senzora kvacila, treba odvesti nekih cca 50km da se ECU prilagodi, i onda je navodno extra smooth gas.

 

Jedine promijene bi trebale biti manje kocenja motora pri pustanju gasa jer se ne isljucuje injektor goriva u motor..., i ako je motor u brzini a podjes ga paliti, nema vise kill zbog kvacila.

 

Svako na svoju odgovornost.

Skoro pa too good to be true, ali hajde, videćemo

 

edit1:

Dakle svodi se na to da lažeš ecu da je kvačilo stisnuto sve vreme.

Postavlja se pitanje da li taj signal utiče na još nešto osim na stvari pomenute u postu?

I malo mi je nelogično ovo kao 50km da se vidi razlika... Kad se promeni signal sa senzora promena treba da bude instant, ne razumem šta ecu treba tu da "uči".

edit2: Nažalost, baš sam u gužvi ovih dana i pitanje je kada ću moći da probam ovo.

Onda mu nekako dođe logično da krene da "puca" iz auspuha na nekoj dužoj nizbrdici sa zatvorenim gasom,,,jer mora negde sagoreti  to +gorivo  , inače voge puca po defaultu i nema tu "rupu" u gasu .  Samo teoretišem...
