Re: Yamaha YZF-R15 version 2.0

Anyone using powertronics ECU here?? Or anyother ECU?? Is it good for full stock bike?? I know I shuld not rev past 10500 with stock even after rev limit is removed. Other than that,is It good with full stock bike??

Re: Yamaha YZF-R15 version 2.0

SVC mechanics have no concept of preventive mainatainance. Unless something is visibly broken or obviously screwed up they won't do anything extra.
Usually they will be happy to change the oil, clean the air filter, lube the chain and let you off.

Regarding the valve clearance, it quite simple: you have to pay for it to get it done, its not included in the free service. Even if you are willing to pay they will be reluctant to open anything in the engine on a new bike. Who knows probably there is reason for the reluctance.

Also, you have to apply your own judgement while going over the maintainance checklist in the manual. For example the manual recommends a valve clearance check every 3k km but i think thats unrealistic. i plan to get it done every 9k km. On the other hand, the manual recommends changing the fork oil every 10k km but from my experience that interval is too long, i will usually get it changed around 8k km. .

Re: Yamaha YZF-R15 version 2.0

yes they have no notion of preventive measures. this is understood about them by just asking them a few questions, it's so obvious in the way they answer your questions. very slack and "arre bhaiya chinta mat kijiye kuch nahin hoga" attitude regarding almost everything, even if you are merely asking a question for your general info, not actually telling them to do it.

i guess valve clearance checkup/adjustment is something a bit tricky, at the risk of opening up something as precious as an engine that too a new one..maybe that's why they are reluctant about it.

will keep that in mind about the manual.

Re: Yamaha YZF-R15 version 2.0

I once decided to go for it. After seeking advice from seniors, I came to know that this ECU cannot be diagnosed by the stock diagnostic tool and the engine malfunction light wont lit up in the meter thereby creating chance of a breakdown which cannot be faslty found out by the svc since the diagnostic tool wont work with the ECU. Hence shelved the plans.

Re: Yamaha YZF-R15 version 2.0

Not exactly true. The engine malfunction and coolant temp lamps have been seconded as shift lights which are programed to light up at 11,000 rpm... however, if and when there is a problem with any of the sensors or over heating, the shift light feature is over ridden and the malfunction and temp lights will work as required. It is true that the diagnostic tool won't work with the ECU. However, if you have Race Dynamics software, you will have complete control of the ECU and it does have a self diagnostic feature.

The problem with Race Dynamics ECU is not with the hardware or the software, its the data in the fuel maps. The data for ignition table and fuel maps needs more refinement which is not possible without doing extensive testing and multiple dyno runs with gas analysis. The unit is good and robust, if one can work out the fuel maps, its really worthwhile as it has the potential to open up the bike even in stock form.

Re: Yamaha YZF-R15 version 2.0

So, for example, if any sensor go kaput, will the diagnostic tool be able to read this just like the stock ECU ?

Re: Yamaha YZF-R15 version 2.0

Not through Yamaha's diagnostic tool. Through the RD software, yes, you will be able to read the error and fault. You will require a cable and laptop (Windows XP and RD software). Once you plug in the whole ECU is open to play around with.

Re: Yamaha YZF-R15 version 2.0

Oh, ok ok . So I cannot take the bike to an svc with this ECU for a diagonstic check. I will need the above said. Does this apply to the Daytona ECU too ?

Re: Yamaha YZF-R15 version 2.0

The Daytona ECU can be used with the Yamaha Diagnostic tool. Actually, the Daytona ECU maps are good as they are 90% stock maps with just a few changes to them. The Daytona ECU has slightly more aggressive ignition map and has the rev limiter remove. Other than these changes its basically a stock ECU.

Re: Yamaha YZF-R15 version 2.0

Thank you for the input bro

Re: Yamaha YZF-R15 version 2.0

Cleared buddy

Re: Yamaha YZF-R15 version 2.0

NO. bad idea. ECU will just remove the rev limit. other then that the ride modes are of minimal changes which is not worth if you buy "only" ecu. for example you you want power of superman but all you get is a costume :P but you are still you. if u know what i mean. and FYI the ECU ranges from INR 10k to 16k.


and @aditya_YZF-R15 I have not much idea about your problem you are facing. but looking at few posts back i think you are getting freaked out with things. keep in mind that the bike will not be smooth through out the whole RPM range. there will be some miss match with the speed and rpm ratio and thats common. going at low speed with higher gear and riding at lower gear with higher speed can cause it. Tappets adjustment is too much to ask for at 800 kms of even before 3k to be max to say. i did tappets adjustment at 10k kms. i have ridden about 10 r15V's and all had vibes at different level and at different speeds. cannot describe the vibes but assume its the normal vibes we get from the bike.

If the bike makes rattling noise or vibes then follow the source of it. and then check out what can be done. sometimes my bike used to make rattling noise at certain rpm, later i closely looked for it and found out my visor was making that noise due to loosening up of a screw.

Re: Yamaha YZF-R15 version 2.0

it's actually not the vibes that's the main concern, it's the (seemingly un-natural) really harsh sound it's making is what's troubling me mainly...like there's a lot of friction being faced by some moving part inside the bike/engine or something..i wish i could have someone record an audio of it...whatever is causing that harsh sound is also causing the buzz-type vibes of course...it's not the more natural and obvious kind of vibes that one gets at high speed on low gear (that is, as one reaches closer and closer to the redline), it's kinda more like it's already past the beginning of the red line by a good margin and heading towards the end of the red line (speaking from previous experiences of abusively riding my scooty and some other bikes of friends), and this just at 4000-5000 RPM (gets worse beyond that)...i don't know if these analogies are giving reasonably accurate imagination of the sound and the vibe-feel to the readers...

it's also nothing like the sounds and vibes one has when at very low speed on a high gear (very low RPM on high gear)..i also made sure all the externally visible nuts and bolts are tight using the toolkit given to us...

i could not go to the SVC today unfortunately, and probably not tomorrow either..but i am certainly going to pester them the day after...of course, as you said, it could turn out nothing's the problem indeed.. but it's really a very bad harsh sound, very un-natural sounding like the engine is highly stressed at just 5000RPM...i need to force them to ride it post 4000 RPM in low gears and look at it, even if just for the peace of my mind i have seen some videos of R15s showing 0-60kmph times and all that, and i never heard that kind of sound in those videos even though the riders were doing 9-10k in 1st, 2nd gears to maximize the pull...

Re: Yamaha YZF-R15 version 2.0

Guys some vibes have creeped in since 2 days. But the vibe is there only in my RHS footpeg alone and tank( only at some rpm in tank ). Checked LHS footpeg and it was normal!! Mysterious
Checked if there is anything loose... All are perfect- chain slack,tyre pressure. Only thing I didnt lube my chain for long after rains. Could this be the problem??

Yamahahahaaa....

[MENTION=56279]siddharthsure[/MENTION]: Lube it and find out. [MENTION=45660]RON[/MENTION]syl: Dafuq what??? "later found out it was my visor..." lmao.. [MENTION=26077]abhimanyu31[/MENTION]: Haven't checked the slack-correction level yet. Will do soon. Thanx. And yes, Mumbai maybe far but I really need an excuse to ride. LolThe threads getting boring people. Photos please.
