Official Rapid Bike Race and Evo Group Buy!!!

I will call them up and check out this device, is it easy to hook up? Is it plug and play. Maybe you could have them set it up to run 91 sense every one can get that grade of gas. I use to have 93 here but the gas station Blew up-they also had real race gas. Going for 86 to 91 gas is a 5 point jump-that's quite a bit-add a H Flow pipercross and a free flow slip-on and it should get maybe close to ten more HP. The bike would have well over a hundred HP then and more torque too.

 

Yeah its plug and play and it will come with a 91 octane tuned ignition map.

 

Here this is the install of the older gen Rapid Bike RB2 I did a year and a half ago:

Please read through the whole thing. The Rapid Bike Racing will be very similar, but it additionally taps in to your factory o2 sensor's, has individual map by gear, has dual mapping map switch capability (for pump gas vs race gas, all motor vs nitrous, fuel economy vs power, pit lane limiter or launch control or increased rev limit etc.....) and it has an 18 different shift cut time capability for shift cut by gear and rev range.

 

That duel mapping could be neat, lets say a map for economy 87 and a HP map for 91. I have maps for my car 91,93 and 96. I am using the 91 map right now. I am not building a race bike just a sporty one for the street , just like my car-same color too.:thumb:

 

Yup that would be the idea. I personally wouldn't mind having a full na map and a 25 hp nitrous shot map.
Third gear power wheelies sound fun

 

Here is the cumulation of all of our hard work and efforts. We did it!

Are they doing a 5G loom?

 

It's being built specifically for the 6th gen, but it might wind up being 5th and 8th gen compatible as well. We will figure it out shortly. I have a feeling the hardware and firmware will be compatible and only the mapping will change, but we won't know for sure until a 5th genner steps up to the plate.

5G and 6G ECU plugs are different, aren't they? Plus the wire routing is different for a few essentials like the injectors and cam/crank angle sensors.

 

Possibly, but there have been successful PCV installs on fifth gens, that were originally made for sixth gens.

Mohawk has confirmed with a successful installed on his year 2000 that the rapid bike racing does in fact fit on the fifth gen, but it will need a custom ignition map, as the 5th and sixth gen vfrs have different ignition tuning.

And in other news:

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.

The blue line is completely stock. The red line is a stock vfr with fuel tuning only. The green line is a completely stock vfr with fuel and ignition tuning adjustments.

 

So what was the end HP ?

 

A few more than stock. Remember this is dyno charts of tuning a stock bike. There really isn't much fuel and ignition adjustments to correct. Now on a bike with aftermarket exhaust and air box mods there would be more gains to be had.

But in reality this is all besides the point. The problem with your question "what are the peak numbers?" Is that this is not about peak numbers. This is about area under the curve. This is a drivability mod. There are huge part throttle and mid range gains to be had with rapid bike tuning.

If you just look at the provided charts you can see that there are enormous gains in the partial throttle and mid range areas. This is where you spend most of your time while riding and this is where you will notice the biggest changes.

 

what US octane fuel is the ignition advancement set for?

 

Euro RON 98 Which is the equivalent of our US 93 octane.

 

You might be able to get away with 91, but I would be careful.

 

looking at the full roll on dyno chart the gains are minimal. so if you factor in the hundreds on this unit + a new exhaust + airbox mods (lol) + paying more for gas maybe squeeze out an extra 10 ponies. Not worth it IMO. Rather put that cash down towards a blackbird.

 

So again read post 33.

 

I see dyno charts broken down into fractional units to make the curve spacing look huge. a gain of 5 ponies is not worth the cash for this. it would be cheaper to purge with a laxative and take a massive $*&T to increase your power to weight ratio.

 

I'm another 5G owner that would be in for an Evo. I don't race it and don't plan on racing it, but a self tuning system would rock.
