PC 111 the cure?

Greetings,
I've read most of the threads concerning the 6th gen lean running but I haven't found the definitive answer to this question- will the re-mapping cure the off-idle stutter? I know that the PC 3 and re mapping seems to smooth out the fuel delivery at speed but my '04 runs fine with no surging at speed; it's the low-speed, slow corner, off-idle stuttering that is truly aggravating. It's really a challenge to be smooth on this bike at low speeds. Any advice would be appreciated (other than parking it and riding my carbed '96 exclusively). Thanks.
Joe

 

PCIII did not fix the off-idle drivability issues on my '04. Time will cure it, you will get used to it and learn to compensate by either using the clutch or keeping it in second gear when negotiating slow turns. I hated it when I first got the bike, but now after 3000 miles I don't even think about it.

 

Are you referring to when you have the throttle completely closed when slowing down for a turn then trying to accelerate, thus getting a strong surge in power?

I'd like a cure for this as well... I've learned to compensate with a little slippage of the clutch, but would like it to be smooth like many other bikes that I have ridden. I would think that this could be tuned out with a power commander but it would take some some tweaking, probably off of a dyno. I think a few hours in an open parking lot with a laptop and it could be tweaked to where it doesn't surge.

 

None of the canned maps address the problem, at least none of the one's I tried with both stock and custom exhaust.

Some others have suggested taking all the slack out of the throttle cable.... I did that as standard practice the first day I had the bike, so I don't know if it makes a difference. There was also something I read about adjusting the throttle bodies, but I don't remember the details.

 

Cable slack doesn't make a difference for me. I've tried with no slack, a little slack, and a lot of slack. I know some of it has to do with VTEC, if not all of it. If I am above 6800 RPM and roll closed then roll back on while still above 6800 RPM, I don't have hardly a surge at all.

I don't have a PC yet but will next year. There are also several mods that I will be doing such as de-PAIRing and de-snorkeling. Everyone says that these mods smooth things out. Coupled with a PC, I see absolutely no reason that the surge can't at least become much more managable.

 

Essentially, yes. It's that low-speed, just off-idle leaness that I can best describe as a stutter; sort of like the FI is feeding the optimal amount of fuel to the cylinders one second, not enough fuel the next second, then enough fuel, etc. ,thereby creating the "stuttering" sensation. Not a good description, I know, but the best that I have. I know it's mapped like that to pass emissions but it clearly causes drivability issues. Oddly, though, my bike doesn't have the 4.5-5K lean surge that plagues a lot of the 6th gens.

 

I've learned to grudgingly adapt to it but if there was a ready cure I would jump all over it. I think what magnifies it for me is that with 2 bikes I'm reminded of it every time I get off the 4th gen and jump onto the 6th gen; they call this progress?

 

Good point. I've sold my CBR and TLR, the VFR is the only bike I ride, maybe that's why I don't notice it as much now.

 

I have a PCIII and a custom map and I can honestly say I don't what the %^$# you guys are talking about.

 

Get a VFR 1200 will solve your problem

 

When I first got my bike, coming from a carbed bike,I found the off on throttle response very abrupt. From what I read at the time on this forum I blocked off the pair valve. It seemed to be better after that. But since then I've added a PC 3 and catless to my sixth generation and all is great. But I also may have gotten use to it and just gotten better on the throttle. I don't really know for sure.

 

Nah, its an issue that exists for sure. I noticed it coming from my carb bike like you and other friends that have ridden it notice it as well. I notice it when I hop on various other bikes as well, as in they don't have the issue.

I've gotten used to it and know its coming as well as how to react to it. Sometimes it does catch me off guard when I'm just kinda relaxed in my riding however.

 

+1 wtf are you guys talking about? :tongue:
