Power Commander On A Standard Bike?

[Guest flashthebiker]

Have an '02 VTEC running BMC air filter and disabled 02 sensors with resistors. Otherwise is stock. Bike runs quite well particularly over 5,000 rpm. The flat spot @ 4,500 rpm spoken about regularly almost went away with fitting of resistors. Has a horrible flat spot at around 2,500 rpm and fuelling generally is weird up to 3,000 rpm. I think I am probably fortunate not to have the many issues others have reported with surging etc, but I'm not happy with how the bike fuels at lower revs. In the 9 months I have had it I have had the engine die on about 4 or 5 occasions, which I again believe is a known issue related to the ECU. If I shut it down and restart all is fine again.

So after that long intro, given I run an almost stock bike will I get any benefit from a PCIII? I will take it to a reputable installer at have it mapped on a dyno. Am I wasting my time and $$ - given that I have a quite good bike with some slightly annoying fuelling issues? I have no intention in replacing the pipes as the cost out weights the benefit, particulary if I then add a PCIII. ...and besides apart from the weight, and perhaps the lack of sound, I don't mind the standard pipes - often get compliments from other bikers.

2,500-3,000 rpm will bog the bike and load it up. Really need to be 3,500+. What it your idle at? Love my pcIII. Cozye's map is the whip. But not really NEEDED, the way you're set-up.

Idle is at 1,200 rpm. I guess what I am looking for is engine response like you get over 5,000 rpm. I don't mean in terms of acceleration just smoother than it is now. Even keeping constant fuelling at around 3,500 - 4,500 rpm is sometimes a challenge (I'm being finicky here but have ridden other bikes that fuel very nicely from idle to redline). It just does not feel right in the right hand...

i would block the PAIR valve first and see where you are. after a week in that state, if still dont like, get pciii w/ coyze's map.

i can tell you that mine runs like butter from 2k to 12k with none of the issues everyone talks about and each step (o2 & pair then pciii) made a big improvement.

Why would you disconnect the 02 sensors? This makes no sense

Defiantly a free mod that will make a big difference.

Part of the nature of the beast with FI. (So I've been told). My old Maxim was never like the VFR, when I first got it. I've heard the new FZ1's are really touchy. Mine's really smooth, compared to how it was, but I had a P.C., on it before I did the pair mod.
