I had my ECU flashed by Steve and color me impressed.  While the additional power at the top end is nice, I really wanted it down lower in the rev range to be more useful in everyday driving.  Sometimes you get what you want and a lot more.  It now pulls a lot stronger from lower in the rpm range.  The bike doesn't have any dead spots off idle and seems to cruise easier. Not too scientific there, but if you get the upgrade you'll know what I mean.  Also, improved fuel economy!  What?  More power and less fuel?  Yup.  It seems the majority of the posts lately have been about how much top end power was available and I think that is missing the best parts of this upgrade.

I have a Muzzy slip on with everything else stock.  65k miles on a 2008.  I wanted the slip on because I wanted to hear the bike and because of aesthetics.   I found I had to control the exhaust popping noises on deceleration by cracking the throttle.  I also had to play with the throttle in other areas to make the engine behave properly.  That is no longer required.

My bike currently has the areap slip on  mounted, and I've been trimming the fuel but haven't been to the dyno yet. Actually I have found a dyno I can purchase and I'm mulling it over... it's a good bit of coin, but I wouldn't have to rely on seting up dyno time anymore, so there is that.

   Anyways, it's hard to accurately predict what might happen when "this" part stacks on "that" part.

   To be honest, I was floored that my bike gained 14 hp with the stock exhaust. Floored to the point that we did several runs showing that gain, then I reflashed my stock map back in and got the 126-128 hp runs, then flashed the ECU back to my flash and back came the 142 hp.  So with that in mind it kind of threw off my idea of "reasonable expectations".

  I was back to the dyno with 2 other concours owners 3 weeks ago. One has a pipe I built with the stock pipe diameter header pipes with a 2 bros slip on. The other has a full area p system. The bike with the pipe I built had incredible low end torque even stronger than the area p system, but from 6000 up the area P system was considerably stronger. The bike with the small tube peaked at 146 and the AreaP bike peaked at 157. These are SAE corrected #, same as my 142 hp. 

   So with those #'s in mind, and IF the stock muffler is more of an impediment to power production than the pipe diameter or the CATS in the stock header  then I think it's possible for a flashed bike with a slip on to get to that mid 140's area... 145, 146, 147, right in there. If it doesn't get any more than the 142 I already have, then we're at the point of realizing the peak power with the stock header.

   So far with the slip on I can say the bike is fast. It was fast before, too. It's so linear it masks the rate at which it accelerates from low rpm so the butt dyno is less effective. I do feel a subtle climb in power at 5000 rpm that I didn't feel with the stock muffler. Subtle but  noticeable none the less. This could be a good sign. Still, I need dyno data, which I will probably have within a couple weeks, and then after that the area P full system goes on, though I doubt it will stay; I'm really liking  the quiet / fast and don't need to be alerting the men in blue that there's an ICBM tearing up the roads in their area of responsibility  :o :o 

   In closing I do want to say this - Guys put on slip ons almost as soon as they buy the bike. 4-500.00 $. Sure there are some weight savings, about 14 lbs, and probably some extra power to be gained, but it absolutely won't achieve the all rpm power gained with my flash. Not comparable. In my mind, putting on a slip on first and then mulling over getting the flash is a bit backwards, because the flash is the obvious bang for the buck winner in that contest. Steve

SISF, thanks for all your scrutinizing and research for interested C14 riders- I'm sure it will pay off handsomely. The only aspect holding me back is the loss of engine braking in the sweepers and twisties. I have developed a riding style that I use extensively in the mountains that involves using 3rd gear and the rear (non-linked) ABS brake pedal to scrub off speed. With the PR4's it works great, and I would hate to lose any of that asset- just sayin', I would hope that the loss is minimal.

I don't see why closing the secondary butterflies sooner would cause there to be less engine braking available.  After all, the main butterflies will quite happily shut down engine air on their own.

Max, does this mean you didn't notice any loss of engine braking after your Guhl flash?

Maxdog,
You are correct.  You do not get 'LESS engine braking'.  It only feels like you do  because the stock flash slams shut the secondaries much 'sooner' and not gradually (and not controlled by YOU).
  You will get used to Steve's flash  right away and you will become  a much  smoother  and a better rider when you use your throttle to control the engine  braking which is the way it SHOULD BE.
If you still have fuel in the tank, you are not lost yet

Nope.  You do have to let off the throttle a little more than before, but the same amount of engine braking is still there.

It isn't lost, hence my posts :)

Engine braking isn't lost, but the perception of it does change a bit.

 In stock form, the throttle is very twitchy, and a small amount of rolling off the throttle leads to a pretty hard feeling of decelleration. This is because the secondaries restrict intake airflow, and they have more impact than the primary throttles in a throttle roll-off.

 Post flash, there is a considerable increase of lower rpm torque, and the natural reaction is to use it, primarily by riding at lower rpm in a higher gear. Couple that with no more throttle twitchiness on roll off, and the "feeling" is a loss of decelleration braking. As others have said, you will kind of "relearn" how to ride the bike. You don't have to manage the twitchy throttle, and the bike is easier to ride. After a few days everything is right in the c-14 world... and better than pre-flash. Steve

This has been a fun read so far. I take delivery of a "new to me" 14 today. Hopefully I can ride it a bit today although there is snow in the forecast. I hope to ride it at least a little before sendin the ECU off to Steve!

Oh, you absolutely want to ride it quite a bit before having a Steve or Ghul ECU flash. Otherwise, you will have no appreciation for how nice the changes are.

 Agreed. I have a 2010 c-14 in the shop that a friend just purchased. He hasn't even ridden it, he had me do the test ride. It has the flies out, a power commander, and an area P slipon. It exhibits a flat spot / lag when the throttle is applied briskly. My flash has none of that. He wants me to put the flies back in and pull the PCV, but I told him he should ride it as delivered for a bit first - then he'd really appreciate what the flash does  :banana :banana  Steve

SISF, thanks for the explanation on engine braking. I've been a good Connie14boy this year, so I hope Santa brings me your ECU flash. :D

The problem is that our riding season in North Dakota is over. It is too short to be sending the ecu away to be flashed even with a fast turn around.
