That Moment When All The Hard Word Finally Pays Off. Rapid Bike Racing Now Available!

The Rapid Bike Racing Kit is now in production and available for all VFR800 VTEC models. Confirmation of 5th and 6th gen use will be made later on. The Rapid Bike Racing features self mapping through the factory O2 sensors. It has full ignition advancing control, Advanced 18 way adjustable Quick shifter control, Engine braking adjustment and RPM limiter extension of 1000 RPMs if requested.

I'm excited and I don't even know what that all means!

Now that's funny, reminds me of an early Jessica Simpson commercial about HD TVs ... :biggrin1:

here are the features

 

Curious. How does this system control engine braking? Does it need data from a wheel speed sensor to do so or does it just look at engine load, rpm & throttle position?

 

I'm going to guess you get to choose between full DFCO to no DFCO at all. (dynamic fuel cut-off)

 

Morning Wood, it's all Good! That moment when all that Hard Wood pays off...

 

That's what I am thinking. It just bypasses the fuel cut by taking in data from the o2 sensors and adding fuel as necessary even while at 0% throttle and high rpms. I will find out for certain tomorrow.

 

Ok I just talked to Yaman at Cycle Pro/ Rapid Bike. He explained the engine braking adjustment feature of the Rapid Bike Racing Module to me in detail. Basically it is a fuel cut eliminator of sorts. It does not utilize the o2 sensors though. What it does is it allows you to add fuel to the 0% throttle column at all rpms (no blocked cells like power commander or bazzaz). It is done by feel, just add some fuel, go for a ride and adjust as necessary. Once you get the 0% throttle higher rpm fueling adjusted to your liking, what you get is a bike that is much less abrupt in the on/off throttle transition at higher rpms. This is something that I do not believe can be accomplished with power commanders and bazzaz units, as they only add or subtract based on a percentage i.e. 10% of zero fuel is still zero fuel.

 

Did Marge and Homer have another kid?

 

Because I love CandyRed I must request the mods make a correction to the thread title purty please.

 

Lol ugh how did I manage to mess up that title....
love you too toe cutter

 

Maybe, considering that blonde is about as smart as Bart ... nicer to look at though :boobies3: ...

Before and after Rapid Bike racing dynos of a 100% stock 2003 VFR800, tuned using the 2 factory narrowband o2 sensors. Keep in mind that this is with no other mods, not even a slip on or air filter. The improvements should be much greater on modified bikes or in the case of tuning each cylinder independently with four o2 sensors.

That is before and after at 100%, 23% and 13% throttle positions. On the 13% throttle you can see the dramatic breakdown of just fuel corrections alone and then the added benefit of tuning the ignition map on top of the fuel map.
