Is that whole USB drive thingie Termi exclusive?

Forgive my ignorance as I say the following. Tuning with a Baz/Rapid/PCV on a dyno and updating UpMaps, does one cancel the other out or how does that work? Does the piggyback map stay unchanged forever or what?

Updates the ECU. A bit different from using a fuel module as the update effects the driveability range (0-4000 rpm) where a fuel module cannot. Also compensates for exhaust flapper valve and charcoal canister removal.

If you update your ECU with an upmap of any kind you will need to readjust your fuel controller, whether it be bazzaz, PCV, etc. in order to gain maximum performance. Usually if you have your ECU flashed properly, dyno tuned and restrictions removed, there is no need for a fuel controller as the ECU serves the same function. ECU is really the "brains" of the bike. A fuel controller is nothing more than giving your "brain" a drug to modify one area of it (Air/Fuel Ratio)

Good deal, thank you. So Rexxer would be a better option than Rapidbike and etc.

personally I think the rexxer option is better than most of those others for most bikes (not all, but most). And yes, I believe that the akrapovic exhaust will have an rexxer tuned ecu shortly.

I want this exhaust. Can anyone find a place with it in stock?

You will have a difficult time finding one that is in stock right now. The Akrapovic Importer shows them currently as estimated to be available by 3/15, well in January it did show 2/15.

PM me if you are interested in a unit.

I have a Panigale with full Akrapovic system on the dyno at the moment.
I am making a custom TuneBoy map for this as I think the Akrapovic system will be popular once people see the results.
I was a little sceptical of the dyno graph posted at the start of this thread.
The bike I have on the dyno has very good performance in the midrange.
I will post the dyno results when I am done.
I will post the graphs showing power delivery at several points through the throttle range.
I don't have before runs for this bike because I aborted the run when the A/F ratio hit 16/1 on the first power run.
I do have a dyno graph of the AR exhaust and I will post the tuned AR system and tuned Akrapovic system as a comparison.
I am also fitting a strain gauge quick shift to this bike, this adds the throttle blip on down shifts.

Wayne are you willing to share the maps to TB customers afterwards?
I am curious how they perform on the modded cans.

Thanks!

Could you also please post a video of it in action? I feel like this exhaust is like a frickin unicorn when it comes to seeing it. All of the vids on YouTube are horrible quality (except the ones antihero posted, but they were short). A lot of members including myself would very much Appreciate it!

I will make the map available.
The normal maps we provide are based on the Ducati fuel maps and you apply a trim file on top.
With this map I am changing the base numbers so this bike will have a zero trim on top.
This method take longer but it will provide a good base map for anyone with the Akrapovic system.
This next screen shot shows the before and after at 38% throttle.
I had added 15% over the entire range and it still hit 16/1 A/F in midrange.
The two red lines are the A/F ratio for front and rear cylinders (with 15% added).
The two blue lines are the front and rear A/F after tuning.
Tuning this throttle row took 2 minutes.

Screen shot

This next image shows the bike on the dyno.
You can see the wide band O2 sensors and the heat protection to stop the hugger melting (Bike is pulled down on dyno so the rear exhaust hoop is closer to hugger)

I notice you have stock rear-sets. If you replace those with Lightechs, you should see a 10-15% increase in HP for your dyno results.

I corrected this for you!
We're talkin akra here

wmcdonal · Nov 11, 2013

I know what you mean about the Unicorn.
When you look at the workmanship in the Akrapovic system you can see why it took some time to come to market.
A work of art...
A nice sound.
Good performance.

gigantor · Nov 11, 2013

i'm really leaning towards getting an akra at this point, meaning some termi slip ons will be for sale shortly.

Nitrouz · Nov 11, 2013

My full termi's will be for sale as early as next week when I have time to put on my Akras.

wmcdonal · Nov 12, 2013

Tuning is complete.
Max power is 190.
All I have left to do is to find the throttle points that make the most power at the mid RPM points.
My dyno shows HP even when holding at a fixed RPM.
I hold the bike at an RPM point then turn the throttle until the power peaks and starts to drop, I then back off to the point that makes the most power for that RPM point. I note down the actual butterfly % open.
I repeat this at the points between 5000 and 8500.
Once I have this data I modify the throttle tables so that these throttle points are what you get when you open the throttle fully.
Fully open throttle plates do not give the highest power in the midrange.

The exhaust has turned a very nice blue colour, looks great.

I will prepare some images and dyno graphs and post these later today or tomorrow.
I will do a little video on my iPhone, I doubt that the iPhone microphone will do the bike justice.

I'm sure I speak for all who are interested in this exhaust when I say very much appreciated wmcdonal.

gigantor · Nov 12, 2013

definitely interested to see the final results.

wmcdonal · Nov 13, 2013

OK.

Here is a little video I took of the bike on the dyno.
You can see the exhaust has a nice blue colour.
The throttle is being controlled from my laptop with the TuneBoy program.
The dyno we have allows the ramp rate to be controlled, the ramp rate in the video is set to 10 kph/sec, this is why the bike climbs through the revs at a fixed rate. It does not mean the bike is not making power, it means the dyno has to work hard to control the power.

Panigale 1199 with Akrapovic full system on Dyno - YouTube

wmcdonal · Nov 13, 2013

This screen shot shows the gain I made by adjusting the throttle opening (Explained above).

You can see I have made some nice gains between 4000 and 8000 RPM.
I was surprised how much the throttle needed to be closed to find the best power (when compared to the Termi full system).
Some points moved back from 70% to 58% throttle opening.

wmcdonal · Nov 13, 2013

Now the good bit, the comparison.

This first graph shows the HP on a standard Panigale vs the Akrapovic Panigale.
I didn't run the standard bike to the limiter because it only had 2000 km on it.

Now the torque

This next graph shows the Akrapovic system compared to the AR system we tuned on our dyno.

And Torque (Akra vs AR).

I don't think any words are required...
