power commander on a 98?

Good stuff guys, Hmm, I'm not finding any info from Rapid if they are supporting anything for the 5th. well it's not obvious on there web site that is. I get our bikes are xxx old, just seems most goodies are for the latest & great machines.

To answer my own question about the accelerator pump functionality, included on that web page is an explanation of the forces at work in EFI and a discussion of the accelerator pump. Now I understand why people suggest trying different fueling functions and observing the results for their bike. There are just too many physical variables and engine setups to know for sure the effect of this without trying it.

 

RAPID BIKE USA

That's the contact info for the North American Rapid Bike dealer (Cycle Pro). The shop owners name is Yaman ( pronounced Yuh Mon ). He is a good friend of mine and has helped me out quite a bit (Cycle pro is 10 minutes from my house). Anyways both 5th gen users "Mohawk" and "Highsidenz" have installed Rapid Bike Racing modules (fuel and ignition control). Both are members on here. Mohawk is making 120 whp (cams and full exhaust etc) and Highsidenz is making 140 whp (825cc, cams, port and polish and full exhaust etc).

I was under the impression that both the Racing (ignition/fuel) and the Evo (fuel only) modules were available for the fifth gens, but looking at the website, its showing that only the evo module is available for you guys, plus since your bike has no factory o2 sensors, if you wanted to do autotuning you would need to purchase a wide band o2 sensor (I am running 4 wide bands on my 2007 with the racing module). I would give Yaman a call and see what he can do for you.

 

Very nice to know

 

I gave Yamin a call, what a dude as in cool. very knowledgeable, only down side like I mention before, is their product is really made for 6th and newer as to be able to take advantage to what it is they have going on. So for a grand, I may get some good numbers, but its looking like a very minor improvement over what the PC3 does, yea it's just fuel mapping, but for the money it's not all bad. might have to look into redoing the factory ecu for ignition timing stuff, but even at that it's old so probably not much out there. sad to say our bikes are being left out due in part to where technologies are going, is what it is. Now the 8th gen guys have it made here. I did read on another thread here and believe Candy had said something along the lines having the injectors tuned/ cleaned and matched, now I know that adds a bit as it did for the cars I ran. Might have to look into this further didn't even think about it, it's the first FI system I've had on a bike

 

Did you message Mohawk and highsidenz?

I realize that I'm joining this party pretty late, but I've always been a little slow. I guess that's why I want more power out of my bike. If what I've read so far is true, my 5th gen VFR with Wolf underseat exhaust and K&N filter would benefit from a PCIII? Any idea what mapping I should use? Or is the PCIII not the way to go?

 

A PC will make your bike smoother and give it a tad more low end. That's about it.

As much as one can get for our dinosaurs, all the cool trinkets are for the newer models, but that said it's a step in the right direction. looking to get mine dial in here in a couple weeks, yippie!!!

 

Basically Anything performance for the sixth gen, is available for the fifth or transfers over to the fifth and vice versa. Fifth gens aren't missing out.

There are competitors such as Rapidbike. Make sure you learn everything you can about using a particular module on your bike. I can tell you about the PC. For your information you may use a PCV on a 5th gen bike.

1) It works fine

2) Dynojet will not provide any support (just quoting them.)

3) There are no version V stock maps for our bikes

4) The physical connection is the same

5) I think the harness for the PCV is shorter due to being designed for the 6th gen. This makes it barely long enough for our bikes. My mechanic had to create shortcuts for routing the harness. He swore himself to sleep that night but it came out fine. I recommend you reserve a Saturday for wire routing.

6) The V allows you to add modules for automatic tuning, an advantage over the III.

7) You can convert a PCIII stock map to the version V but there is a bug to get around. (I can help with bug.) When I finally got an appropriate map converted it was far too lean at 3500 anyway. Ironically the 2002-2006 Micron map worked great out of the box.

8) If you do not have access to a trusted dyno you can get Autotune or Wide Band 2. Get the Wide Band 2. This has the Autotune hardware but also has more functionality. When I looked the WB2 was cheaper than Autotune. While Dynojet did not answer that question in my e-mail, I suspect it is cheaper because it is newer and they were able to spend the effort reducing the cost of the components or assembly.

9) I think but am unsure that you need to bypass your O2 sensor and use sensors made for the Wide Band unit. I don't have an O2 sensor so it is not an issue pre-2000.

 

My research on Rapidbike (note the PDF on this web page for part numbers.)

http://www.dimsport.it/en/tuning-line/rapidbike/bike/honda/vfr-800/


I found the part numbers and googled them, and could not even find a distributor selling in US dollars. From the units posted in Euros it seems that the total cost of the EVO kit is similar to PC + tuning kit and the Race unit is more at roughly $670. Before I consider getting a Wide Band 2 I thought I would evaluate your #1 recommendation but I now think that my pursuit of the Power Commander hardware is the best route due to its ubiquity.

This is like deciding on a PC versus a Mac. Mac may be better, but the software selection, number of users, and the ability to swap ideas and understand the same language, keeps most of us on Windows PCs. Windows is not the best, but the best compromise. This entire community can support each other with the Dynojet hardware.

Rapidbike must get the cost down. They must improve their marketing and get themselves highly visible outside of racing circles. They might be the best thing known to man but they must work on mainstreaming their products.

Thanks, from using rapidbike.com, I never made it to this US site. So I follow the url and select the shopping tab. Holy crap! The EVO is $880 for 5th gen but $555 for 6th gen! From Dynojet we learned that these bikes work the same way!

For the race unit we get this gem:

And NOTE: DO NOT PURCHASE THIS KIT FOR EARLIER YEAR VFR800 , We will have a specific kit for 98-01 VFR800 SOON

Enough of the psychological torture Rapidbike, I think I'm done!

 

Yeah I am sure its more because the 98-99s do not have o2 sensors, so they need a my tuning bike (wide band o2 sensor) to work right.

Are you reading?

To which I reply to them, why an added module? With Dynojet I just add the Bosch O2 sensor and the hardware is the same.

Also that warning is wrong about the 2000 and 2001 bikes which do in fact have an O2 sensor.

 

^ What they said, and why I said what I did...... Bottom line, the PC3 maybe 5 for the 98-99 is the best one can get for the money, all though I'm still working on getting a ignition curve outa the stock ecu. My Toyota MR2 ecu was send it in it gets redone.. gets me thinking why not the VFR, probably more a case of having the right people that know the to do and if warranted for the time vs. money, there's no doubt there's not a huge market, Yet?

 

okay for future reference, regarding the vfr800 (Fifth and sixth gen):

If you want ignition adjust-ability and you have money to play, Rapid Bike Racing is the answer.

If you can make due with fuel only and money is an issue, Power Commander is the answer.

That is really all there is to it.

 

What do you mean by ignition curve? I usually take this to mean timing curve. Our bikes cannot alter the timing, right?
