I can only comment in terms of sound since I've heard lardawge's pani which has the akra on it. Mine has the standard pipes and although it sounds decent, next to the akra it sounds nothing like it. Akra has a deeper bass (rumble) and only gets more mean with more grunt as the rpms increase whereas the standard pipes kinda get tinny sounding higher in the rpms. The lighter weight n increase power and torque are obvious but the sound is definitely louder than the termi full as well. Even if someone has a full termi, they could easily sell it n add to it some n get the akra. I for sure will be getting the akra down the road.

The Akra doesn't any removable baffles, right? And at idle and just putting around (i.e. going up driveway, putting through neighborhood) is it noticeably louder than stock? Or only when you start getting on it?

Maybe slightly louder than stock but you can definitely tell the difference in tone. It has a more noticeable rumble than stock even at low rpms. It's not obnoxiously loud. I'm not sure about the removable baffles. I don't think it has any. I could be wrong about that though. I just know its sound makes me want it on my bike. Honestly don't even care as much about the performance aspect of it. The bike is plenty fast as is and the pipes + tune may fix that dip in torque but ultimately the sound is my only reason for wanting it. Yea, expensive ass sound I'm after lol. At least it looks cool too.

Has anyone put it on without tuning it? I just wonder if you couldn't wait to mount it, would it run ok/better until properly tuned.

just checked my akras...it does have removable baffles just like the termi's.

I'm sure it would be similar to how cars are. I'm sure it would run just fine but probably very ...... due to the afr being all over the place, therefore not really ideal to be getting on the throttle with an untuned full system. I wouldn't do it personally. I did install a couple of parts on my evo couple years ago before I got my major parts ordered n taken to a shop for a pro tune but I made sure to stay out of boost at all times.

not even the stock system is properly tuned due to official restrictions.

It does have removable baffles. I have not ran it with them in so I don't know how much it tames the noise. They are loud but not in an obnoxious way. Cars can def hear me coming.

The bike I tuned had the exhaust fitted with the standard ECU.
He said it was hard to start and ran very poorly.
I was not prepared to do a base run on the bike because it was very lean.
I am sure it would have been OK in the upper RPM range, I just felt it was time to abort the run when the A/F hit 16/1 in the midrange.

TricoloreSF · Nov 18, 2013

Wayne, did you ever end up developing a launch control for the ECU?

So it sounds like I need to get the Akra tune for my Tuneboy, and install it asap after installing the pipe.

any reason for going with Tuneboy as opposed to Rexxer

when will the akra tune for the tuneboy be posted?

Just let me look into a crystal ball or how long is a piece of string.

I did the last tests on the bike yesterday.
The bike is getting picked up in half an hour.
I will send the map to any of our customers who request it.

The map I have done for this bike will be an Akrapovic specific map. I did this because of the vast different in fuel requirement when compared to the Termi or standard mapping.

The map has the Cruise Control and the strain gauge quick shifter, the strain gauge shifter option allows clutchless down shifts (ECU blips the throttle on down shifts to unload the gearbox).

The map changes the thermo fan settings, the fan comes on at 103 degrees on the first heat cycle then comes on at 91 after that. This keeps the engine temp down to aid in rider comfort.

Like all the TuneBoy maps you can play around with the fuel trims to get the best from your bike, I would suggest a test ride with +5% then another with -5%, then use the one that feels the best while riding.

You can see from the A/F graphs I posted that the bike is tuned over the entire throttle range.
Has anyone posted equivalent info on the A/F and performance with the RexXer flash.

If you don't want any of these features and you want to go with a map that you can't adjust you can use the RexXer flash.

RexXer provide a reflash tool, TuneBoy provide a tuning tool.

In the end the choice is up to you guys (and girls).

What octane fuel was this map tuned on? Here in the states, some states have 93 available while some of us only have 91 octane available. Just wondering what the octane difference is in the fuel during the tune and how that would effect this map for all potential akra owners all over the world.

wmcdonal · Nov 21, 2013

93 RON or MON

The 98 RON in Australia is 88 MON

Number one because I already bough the Tuneboy! Second because of the features mentioned above - cruise control and unlimited possibilities. Not to mention, there is experience on this forum and charts to support it for Tuneboy, Rexxer not so much.

How would I be able to contact you about this map? Any clue on the cost?

if you purchase the tuneboy unit

Now I'm confused as to why I have to purchase the tuneboy? Ok, here is my situation. I want to purchase the akra system. Can someone tell me what else I have to buy in order to achieve the best possible performance out of the system?? Please provide a list of things for me and where I could buy them. Sorry for the redundancy but i still haven't found a clear cut answer.
