I've found most of the information I need for these mods in rc51.org and there are few details that I'd appreciate if someone could clear them up for me.
About the flapper mod, is there any advantage, beside looks of getting D,K's block?
and for soft rav mode, what is the deal with that CD-audio cable that they say you need to buy? I didn't see any use of it but taking one wire off and connecting the hole #4 from the black connector, to black and withe wire in gray connector. is that correct? ( I understand I have to use a pin that is going to fit ECU)
I just don't want to damage the ECU.

soft rev.


also for the softrev print out the wiring diagram that rogue has. It is helpful...yet my 03 was slightly diffent...but I figured it out.

The only advantage to dk's plug is the look. You can get the same effect without it.

The soft limiter I dont know but I am researching it myself cause its on my plate for this winter

[TGZ13]

Question....

Is it worth doing the soft rev now (no PCIII) if I plan on getting a PCIII down the road?

Actually I did find that post, but I couldn't find what I need in it, its more about the benefit you get with soft rav mod, which I already knew,
Basically my question is this mod can be done just by connecting the hole #4 in black connector to black and white wire in gray connector? ( I see your point that different years may have different color, or be slightly different) but then again that cd-audio cable thing got me confuse, and I want to make sure before I do it.

When I was searching for this mod, I came cross the answer for your question, the most benefit of using power commander( for this mod), is that any time you'd like to go back 100% stock, you can do it.

I forgot to mention that my bike is 01 RC51

I have no interest in going backwards (back to stock). My 00 is my baby so it wont be leaving till I cant walk anymore.

Soft Limiter - What is it?

another...I think I follow you, and yes, if I have the idea right. but I used that CD cable they talk about with a scotch lock to that wire. Did you see the pics on rogue?

[showmethebombs]

You saw this right? I see that in your post you saw it...but the pic with the scotch lock is what I did.

Thats the diagram with the PC correct? I guess I will just wait till I have a PCIII

Well, it is, but I didn't use the PCIIIr to do it. All you do is splice into that one wire, and then use the dead port in the harness. just like the pic. That is what I did. I never messed with the Power commander.

I just wanted to show that scotch lock.

Thank you sir, I've got what I was looking for

[sonofarex]

so what i've gathered from these threads while skimming them...

flapper valve is only for looks
soft rev limiter is a good call as long as you always use premium (i do anyway)
soft rev mod is different on the 00-01 models than the diagrams show on the rogue site

correct me if i'm wrong on these

and also i was wondering what is the PAIR mod that i saw mentioned a few times

[RC51Mike]

The flapper mod eliminates its function, keeping it open all the time and takes out a dip in the torque curve mid-range somewhere. The "looks" is just the cap you can buy in lieu of leaving the vacuum diaphram in place. You can just cork the vacuum line or rip out the whole guts. Soft rev mod makes a noticable difference and the RC wants premium anyway because it lacks a knock sensor.

[RC51Mike]

oh, yeah, the PAIR mod is to remove some smog plumbing that from what I read saves weight but no gain in performance, although I could be wrong.

[sonofarex]

thanks for the help...

final question being... is the soft rev mod different on the 01?

I think the one in the diagram was on an SP1 so that should be what you need

[sonofarex]

well right on... looks like i have my work cut out for me

I should be doing mine in a week or 2 on my '00 I will let ya know how it goes

[abtech]

Removing the PAIR system will also help eliminate back firing on decel. It also makes the bike easier to setup on the dyno (as the PAIR system routes fresh air into the exhaust ports thereby skewing the 02 readings during dyno tuning). The hose can be pinched as well, but why bother . . .

OK, wrong may be a little harsh but let me clarify somethings for you.

1. The soft rev elimination does not require the use of premium fuel.
2. The soft rev mod does not differ for different year models; it differs if you have a PCII or PCIIIR (and yes, you can put a PCII on a >02 RC51.) On the PCII, basically you could wire to the Power Commander harness instead of the stock harness, allowing you to remove it for warranty purposes. Since PCIIIr's and later control injector dwell directly, they do not plug into the ECU like so reliminating the soft rev requires tapping the stock harness.

i just looked at the diagram and compared it to my '03 and it is the same. I am also considering tackling this mod.

[Rigor]

the PAIR mod is suggested for anyone that's running aftermarket pipes, as the decelleration backfiring can be enough to blow out stock header gaskets, at the head.

aftermarket pipes have less backpressure, making it much more noticable.

the decelleration popping is much less after the mod.

BWAAAAAAHAAAAAAAAAHAAAAAAAAAAA!

Did you really type that with a straight face?
