Ah! Ok...
So the ECU controls something or controls somehow the amount of fuel that goes to the Carb.... and also continues to controls on the ignition...
I have some question as to why would anybody want to do that?
The only merit I can think off is where the ECU has preset configs... something like a mode switcher...

Does the FZ need something like this?

I would do this to see which is working better. Carb or FI for my engine.
If I have to switch the entire system from FI to carb, I'll need to run a new magneto pick-up point(which is utterly complex), new ignition timing, get another CDI unit, etc etc.
In this case, I can just disconnect the fuelling and run a carb and vice versa. But then, its never easy as described.
Switching from one fuelling system to the other cant be done with any stock/pre-programmed ECU as the system will then run on a limp mode and severely retard ignition timing thru revs. Simply put, the engine wont rev beyond 5-6krpm.
You need a fully programmable ECU which can run with your own parameters. Its only possible then.

Thanks man (as always)
Time to google and learn more...!

Trust me, you wont find much on this context if you google too. People either run Carb + CDI or Fi + ECU. Hardly anyone would perform a hybrid adventure like this, coz its very complex.

Which is why the thanks to you man...

I was and am still a complete noob in all this.... but heck atleast now I can understand some bits of it!

Confirmed about that violet thingie..it indeed is a ballast for HID!

There's only one HID on the R15, and that was on the left reflector(from rider's view). I previously just checked the other reflector and assumed there's no HID. The current Yamaha setup uses HID in left reflector and halogen in the right reflector.

And unlike what everybody here is saying power is not gonna be upped to 25bhp. It's mostly probably going to be around 22-23bhp with the full kit on. Exhaust alone is gonna cost around 15 to 16k..highly unaffordable for me!

**shiv81192** · 07-20-2009, 09:00 PM

on the car and bike show they said there are 3 stages of performance kits one with just the exhaust for 17k and the second package has an exhaust and the ecu at around 35k and the third package has everything in it for 55k .Thats just too much

stock r15 17 ps. yamaha say's after racing kit 30% more power means 22.1ps

Yamaha claiming 50 % increase is madness

why dont you see dyno jet usa claims ,there is only 3 or 4 bhp increase for the ninja 250 with yoshi pipes with re jetted carbs ,airbox mod
even if i had this same set up on my fz the power increase wud be in 0.2146 or some thing like that in proportion of 250cc to 150 cc

If only this forum had a capability to put up expressions too...then it'd be easy for us to decipher your expression there!

yesterday i was watching NDTV Car n Bike show in which they mentioned details about the Racing kits they told that these kits are not road legal they are specially designed for the track only. they also said that these kits includes ecu, large front disk, silencer n etc (dont remember others) they also mentioned that that the silencer only enchances the 30% of the power and after installing all these kits bike will gain 8-12km per hour speed and they also mentioned that the accrelation also fast (FZ n YZF R15) earlier the rev limiter was 9k rpm now the rev-limiter can cross 10k rpm with an ease (bike is now powered with 21 ps) and guys all these kits are available for Rs 53000 (in which silencer only cost is Rs 16000)

Stock R15 is 16bhp. Bhp is not ps.
If Yamaha is claiming 22-23bhp, they have for sure lost it somewhere. 30% increase in power with a simple ECU (which is not programmable and has only a higher cut-off), few fancy sprokets, an over-rated expensive exhaust and a mild camshaft?
Its a big joke. Best part is, all are buying this joke so seriously on this forum and everywhere else. And this joke costs 55k. Super!

**Lost Soul** · 07-22-2009, 04:38 PM

Guys all these 22ps and 30 % power are utter BS , can we atleast have some image or link from yamaha that shows them claiming this power figure . something like an pic from the brochure of the race kits .

Correction, 1ps=0.987bhp, 17ps= 17*0.987=16.779bhp

Jus pulling ur leg lol, don't take it the other way

Has it been confirmed that the new ECU also holds the same map? Not doubting your knowledge here, but this is a genuine question that I'm curious to find an answer for...
Also, is this race cam they're providing milder than the one your Stage-1 bike is running on?
