Just buy the autotune and skip the dyno.
The Flash Tune Datalink cable isn't really intended to supply you with a "flash". It is intended to supply you with a TOOL to develop your own "flash".Rodge said:Hi Guys, this seems to be the perfect solution for me, can somebody confirm that the 91 oct based map removes the timing restriction in 1-2-3 gears?
From the website "- Removal of all gear based or speed dependent restrictions, TRE"
Did not see it discussed in this tread, is it a function of timing values in the timing tables?...
Will introduce myself in the proper section...

For just an Akra slip on I don't think you will gain much from a dyno tune. Do you feel you have fueling issues right now?jvl said:I hit a couple of issues on my flashing project. First one was that my bike was actually a 2011 bike despite being sold to me from a dealer as 2012, so I have the -00 ECU. I was planning on sending my ecu to be read during the winter so I could flash it for the next season. Luckily someone already did that and the -00 is available in the software. The second issue was that the installation instructions were wrong for the -00 so there was some hassle with that, but I did get the ecu flashed with the bench harness. All I have changed for now is the throttle and fan temps and those worked ok.
I just had 20 000km maintenance done and they increased the CO setting to 12 to richen it up, apparently the plugs showed that it has been running slightly lean. I have the akrapovic slip-on so I guess my next test will be to import the akra map from powercommander. I also have a powercommander for the bike, got it for my troubles from the dealer so maybe I install that aswell and get it tuned at a dyno or something. Local tuner had never seen ftecu program but he was thinking that there should be no problems tuning the bike with that instead of a powercommander so maybe I will see if they can do that for me.
Thanks to whom ever sent their -00 for a read!
My main issue is the jumpy throttle at low revs and I don't know what causes it and the dealer was not able to do anything about it. Might not be fueling related.avc8130 said:For just an Akra slip on I don't think you will gain much from a dyno tune. Do you feel you have fueling issues right now?
You can import the PCV map for the Akra and I bet you will be pretty happy.
Have you worked on throttle maps?

I've tried A LOT with the throttle. If you feel it is "jumpy" you need to smooth the map. Dull the wrist vs TB in the areas that are jumpy.jvl said:My main issue is the jumpy throttle at low revs and I don't know what causes it and the dealer was not able to do anything about it.

Only things I have modified so far are the fan temps and the throttle maps. I now have the throttle map value to be directly the value of the throttle no matter what the revs are. The change makes a big difference and the bike feels a lot better with it. I get TCS blinking all the time now.
I got some ideas for changing the throttle more, like maybe I will soften the low rev area and do the opposite for the higher revs. Less aggressive throttle for low revs and more aggressive for high. Have you tried anything like this?
The jumpiness is only with low revs just above 2000 and steady throttle after a little engine braking. This situation doesn't come up that often but when it does, it is very annoying. The bike feels like it can not decide if its supposed to engine break or go. I was also thinking that this might be about the ECU trying to do something with the o2 sensors in a loop that makes no sense for the revs, but this was just guessing. I don't think this could be fixed with throttle maps because it does not happen if I go through the revs with the throttle steadily increasing. The bike pulls fine on flat while idling, but does not do so around those revs (occasionally).avc8130 said:I've tried A LOT with the throttle. If you feel it is "jumpy" you need to smooth the map.

Nope, I only have the Akra.avc8130 said:Arrow headers?

Hmm. I have some theories on this, but I haven't been 100% able to resolve this myself.jvl said:Nope, I only have the Akra.
Interesting. I did not know that. Something like that could explain it. Any idea why such a thing exists? I have to admit, I don't quite understand these tables. Is TPS vs RPM for setting the fueling based on throttle position and rpm? then what is the MAP vs RPM?avc8130 said:Hmm.

You can try changing the TPM vs MAP value in that area. I think part of the issue is the bike switching between MAP and TPS based fueling in that area.

btw one difference between -00 and -30 is that in -00 there is no such thing as MAP-TPS Bias.
Give it a shot. The nice thing about controlling your own flash if that if you don't like it, just flash it back!jvl said:Ah yes, it is in the FAQ :-[ Thanks!
I'd like to test setting the bias so that it is always using TPS vs RPM. If that would eliminate the problem I could prove you right. I read about some r1 guy removing o2 sensors and using the bias to make them obsolete (=no error when removed), I also remember reading that you can remove o2 sensors if you do the ecu unleashed flash. These two things make me believe that ecu unleashed might be doing this. This was actually bothering earlier me about the ecu unleashed, how could the sensors be removed and the ecu to leave the closed loop.
Exactly!avc8130 said:Give it a shot. The nice thing about controlling your own flash if that if you don't like it, just flash it back!

I have Arrow headers. I've been fighting surging and fueling "fun" for quite a while. I refuse to accept any burble or bobble. I've read so many reports that "add 5% fuel" and it goes away, but I've been there, tried that, stumbled away.jvl said:Exactly!
Did you have this behavior on your bike or some other bike that you have flashed?
I have the Gen2 ECU-U map and can confirm they have NOT solved this surging with Arrow Headers, the UK ECU-U dealer provided a lot of feedback and did a lot of dyno work with ECU-U using a customers bike and were never able to completely remove the surge.jvl said:These two things make me believe that ecu unleashed might be doing this.
