I don't think it's a thing of being 'better'. Twinmax can tell you imbalance between 2 cylinders. A carbtune will tell you vacuum pressure of one or more cylinders. Both are used for the same purpose, but they use a different approach.

What I understand is that there isn't a whole lot to do other than finetuning with the Powercommander because the BMW mototronic runs in closed loop between 10% and 80% throttle. Having a PC with wideband O2 sensor and adjusted for a proper A/F ratio of 13.8 takes care of most. But I could be wrong....

What you need the extra clearance for? First thing that hits the ground are the valve covers..

It's a replacement that comes with the PC. It is able to read any value, allowing you to set the PC to a user defined A/F ratio, whereas the OE sensor can only read 1.

The rear disc would look better with the matching front, but hey, it came with the bike. Don't always have all the choice when buying 2nd hand.

Then again, it came pretty much pre-farkled, so I can spend more money on some other stuff that I'd like.

Laser or Staintune, it already has a K&N. Possibly an induct mod (if I can find some pics of where and how to drill; that CF duct is too expensive and only really works at highspeed)

Oops, slip of the finger. Of course it's R.

And yes, it's loud. Ripped off the cans for some stock ones, while I decide on either a Staintune or Laser.

Thanks Gromit, I introduced myself in another thread too.

BTW gromit, did you happen to ride a VFR in the past, and spend time on the VFR forums? Your nick seems to be familiar.

Having used the search and doing lots of reading, I may be opening a can of worms but I still want to ask. What is better? The powercommander w/ wideband O2, or getting a chip for the mototronic? I understand a lot of these chips are tuned for max throttle, which I couldn't care less about. I also h...

Been registered for a while now, but never said hello. :) Just bought me R11S 2 weeks ago, and it has been one of the best buys I have done. Previous bike was an FJR and I wanted something more sporty, lighter and with more soul than the turbine FJR. Accidentally came across this very pretty S, went...
