Dyno results....Re-dyno after reflash?

[Guth_imp]

I just had my bike Dyno'd today. I have a TSR air funnel K&N air filter and a custom slip on exhaust from cone engineering. I had the mods on before the tune. The baseline was 86.39 hp and 68.22 torque and I ended up with 91.19 hp and 71.40 torque. I'm pretty happy with the results. I plan on getting my bike reflas he'd in the future to remove all the de tunes just to have a little more response and a little more on the top end doesn't hurt. My question is would another dyno be worth it after a reflash or will the reflash just improve upon my previous dyno?

Not to offend you
theoretically.. 4.8 HP & 3.18 torque more = = sorry, but for me not worth digging (compared to baseline). How much did you spend on mods?
I'd like to see results BEFORE mods, for further assessment please.

pb The benefit is in cleaning up throttle response, reducing driveline lash (fuel cut eliminated) and popping, more efficiency, and generally improving the rideability of the bike. A little bit more power but an improved power band can really help the feel of the bike.

That said, I never did get around to sending my ECU to Don Guhl because the 2013, mine anyway, ran very well.

I would not want to think I'd have to reflash a 2017 to cure any problems. I hope they've gotten that sorted out with the Euro 4 and so on.

How about an image of the dyno run to see the entire powerband?

Dyno image BEFORE and after mods, otherwise not interested...

Generally agree with your statement ULA..makes logic sense...I used to modified 2-stroke engines with very great results (much cheaper/easier than 4-strokes)....four decades ago = history.
My point is , that aftermarket engine electronics offer so much bull poop in "increasing HP" that, I want other members to be aware of it, before $pending. Your bike, your time, your pleasure/satisfaction and money spent....is it worth it in this case?.. I someone tells me this: I have larger: valves, intake/exhaust ports, diameter exhaust pipes, higher volume fuel pump/injectors, different shape of combustion chamber, lighter pistons, with connecting rods, cams!! and completely reprogrammed ECM +++ more = big bak$ spent = for sure more power...now another issue comes into consideration:: pollution, heat/NOx.....and there we go again into another "argument" = friendly
Hope to talk to you soon

Any interest in cams? lol

Not likely to be any real discussion about power mods for this bike. Not much can be done with it, except possibly cams.

The Triumph Hi-Torque 900 is a good example, though.

A company determined that engine is extremely understressed and have developed a set of cams that will produce nearly the same power as the T120 engine.

Only problem is the chassis cannot handle that power, and the bike only weighs a very few pounds less than the T120/Thruxton.

So just buy the Thruxton and get a bike designed to handle and be safely ridden with that power level, rather than destroy or compromise the handling and reliability of your 900.

Same would go for the CB1100. For SURE hotter cams could crank up the HP, and the engine could probably stand another 15 HP without any problem. But then we still have the issue of the old-school chassis and suspension.

Notice Honda did NOTHING in terms of increasing power on the '17 model. Just refinements to the powerband, suspension, and handling.

The bike just does not need, and cannot benefit from, any more power.

I that that Honda did increase the power somewhat in the 2017 model — this would help offset the weight gain.

I don't begrudge anyone who wants to focus on increasing the power of the CB1100. Even if the gains seem rather small for the money invested, it if makes someone happy and they still enjoy all the other aspects that this bike brings to the table then more power to them (pun fully intended).
Also, while someone might not see too much difference on the dyno chart from adding a device like a power commander, I do believe that the changes that they feel when riding the bike are more significant. From that standpoint I can understand this mod in particular.
