Power Commander

Anyone use a power commander or anything to get a custom tune going on this bike ('14 vfr800)?  If so, what were the results?  In my car I saw a solid +20hp from tuning for premium...

That is an interesting question... I've finally test one whitout honda's driver and I found it less powerfull than my old 2000 which is having 116000km... 

If a power commander can improve that much, that'd be a nice buy  :happy:

Just had one fitted, Bhp only up by 3 but it is so much smoother, a different bike and it was great before

From experiences of 6th gen owners with the same VTEC motor, large HP gains using a PC are elusive.  PC's are best to smooth out throttle response issues - stumbling / surging, etc that are common problem with 6th gens.  The 8th gen may have those refined out, but significant HP gains are unlikely. 

 3 more ponies and improved throttle response sounds like a decent upgrade as this bike could use a few more hp, how about with a slip on, airfilter and pc? Anybody do those mods yet to the 8th generation vfr?

I have an appointment with dynojet in preston in a couple of weeks to provide them my bike for the purposes of generating a map. It will cover the 8th gen, honda sports kit akro can and k&n air filter. The best map available at the moment is from dynojet's US site, it has baffle out exhaust but stock air, there is a noticeable improvement however, watch this space for the full map and hopefully more power.

Yum, yum, can't wait.  don't forget to post the results, just need a little more power  :goofy:

My 1999 Audi has separate (factory) maps for 95 and 98. Never tried 95 because I don't trust the knock sensors on such an old car, but I read the difference is not noticeable.
On the other hand, foreign bikes are tuned for 91, which hasn't been available here for decades.

Right then, My ride to Preston happened yesterday, Fair play to the bike giving me relative comfort for 460 miles, 8 hrs riding was looking like a challenge but was surprisingly easy.

Now the results, Firstly, the US map was close according to Richard, it did run rich at some points though losing power as a result.

Not to worry, the UK map will be out shortly. :cheerleader:

My bike was a happy guinea pig.

Torque went from 57.73 to 58.92 ft-ibs and HP was 102.91, now it's 105.92. It doesn't sound like much, and to be honest, it's not, however having that power available throughout the range unlike before has given the bike a much stronger pull in any gear.

Considering the numbers of this dyno test on a stock interceptor, it may be that the sports pack alone makes the biggest difference.

The power commander has smoothed out some flat spots evident in the graph and reduced the dip that appears when the vtec engages.

My ride home was fun in places, able to rag the bike with quite alot more power in places where it wasn't before.

The US graph also shows power dropping off sharply at 10k, even without the PCV mine keeps going and doesn't start to drop until 10.6k at which point it's a much slower decline, not sure if this is due to different RON in fuels or the akro can. For more comparison, at 11k the US test shows about 90hp, mine was showing 104hp

As soon as Richard sends me the soft copies, I'll post them up.

The map will be for the akro can available with the sports pack (baffle out) and a fresh Honda OEM or relatively new K&N air filter. Fuel was standard 95 RON.

I hope this is of some help to people considering their options, I'd say one won't work without the other so you'd need the sports pack or at least a good exhaust to bring the power out and the PCV to smooth and enhance the delivery.

All in all, very happy and well worth the money.

Edit: Forgot to mention, 70mph avg on the way there getting 53mpg according to fuelio, the way back was not completed as I filled up 40 miles in after the bike had been on the dyno and I still have some fuel left, the jury's out on the new map but looking at the dash readout, not alot different at motorway speeds.

Thanks for the description, both quantitative and qualitative, of what the PC has done for your bike.  Will be interested to hear about its affect on fuel economy-- though really that's secondary.

The KTM Super Duke has caught my eye and sure, 1290cc is going to put out some torque in V-twin format, but continuing to read about how smooth the Gen 8 fueling is and even better with some mapping work, makes me think this could be a viable replacement for my Gen 6 ('02).
