Thread: Power commander or not

If the bike was tuned for it then put it back in...

If it was properly mapped the powercommander should give you smoother throttle operation which is better than 1hp gain

I'm thinking of installing one just for that same reason. First and second gear turn exits are a bit scary at that throttle on moment... never know how's hard it'll kick...


Did you feel a big difference when you took it out?

Yeah, to a degree. But the 929/954s had especially "notchy" fuel injection, with an abrupt on/off feeling on throttle application, no matter how smoothly you tried to apply it. The PC does a good job of smoothing this out. I don't know how it is on the newer 1000RRs.

With the pc it had so much power that it would pull the wheel in first with partial throttle around 6500 - 7000, now there is a bit of a surge at 7000 but the wheel hasn't come up yet even at WOT.


What kind of rpms are you talking about? Since I ride on the street I'm coming out of the corners quite slowly and with rpms under 5000 it feels as smooth as can be, even with lots of throttle.

I think the stock has a dip around 3000. I don't remember, but there was a more on/off feel with my 929 than any other bike I've owned. What helped on the track more than the PC (when I had just a slip on) was a gearing change, actually.

For street riding it does not bother me since I don't try to come off the corners fast.
On the track, perhaps cause I'm not smooth enough, I've had the rear coming around a few times on first and second gears after a having the throttle all the way off and then opening it.
If it always happened with some consistency I would expect it, but is not a consistent issue. At times I can just roll on the throttle smoothly and it will work fine, others is an abrupt transition from no power to too much power in a second. It might be my riding style, or lack of it, or perhaps the throttle cable is too loose...
I was hopping a PCIII would at least help.
Hopefully I'll get this sorted at Grattan.

Forgot about this one. Yeah, check the play in the throttle. I found if there was too much movement before it worked, it didn't help my smoothness any. You need a bit of play, but not much.

Yes, 3-4k, the solution to that problem is to not let it get that low while riding curves.

Use the thing under your left boot.

Yup! Gearing change helped keep the rpms up on tight corners, too! Mine's custom mapped, not a problem anymore. Besides, I was winding the crap out of it at the track on Monday!

Speaking of the track, the new Eagle Canyon track by Denton is open or opening soon and LSTD is doing a day out there July 16th. I am thinking of going. Let me know if you are interested, it is supposed to be somewhere near Denton.

Oh yeah, back on topic, I had the same problem on the tuono, and still somewhat do to an extent. I majorly shortened the final drive gearing and now I only use first for leaving from a stop. Second gear exits are still an experience but moreso for keeping the front end down than the rear stepping out. I raised up my forks in the tree and that helped on that front. Anyways, my bike has instant on power but I am not sure if that is due to fuel injection mapping, gearing, v-twin characteristics, or a mixture. I didn't have a PCII on my 929 either and didnt really notice it not being smooth. Maybe it was there and I didn't realize it. Now when I ride a VFR800 it feels anemic because there isn't the instant thrust at the twist of the throttle.

I'll try. I hope I can push some more days off of work. Thanks for the heads up. Are you going to CMRA at MSR this weekend? I'll be there Sat morning and hopefully all Sunday.
