Thought I would post this for those interested.

The higher runs are after Evo was intalled and a Motty AFR close loop system running. Took a little bit to get the AFR unit tuning properly as it was disabling self tuning due to high engine temps on dyno. Finally figured this out and raised the high temperature limit and it worked fine after that. It only took a few pulls once I had the temp limits fixed and it jumped from 171 to 176. Took it for a ride today and it just keeps getting better and better. have set the AFR at 13.2, will be going back to the dyno in 2 weeks and will have a bit more of a play with other AFR ratios for best power.

Interesting to see that the baseline on the other sheet is 151. This is the same bike with 1000kms and completely stock with all the crap still on it, while the Akra evo with Motty AFR pulled a 176. Just goes to show how restrictive the exhaust is. The 151 run was done quick and we didnt hook up the RPMs it was done in 5th gear with speed scale on bottom. The Akra runs were done in 6th with RPM on bottom

Was all done on the same dyno but differant days. The other line with the 151 run, was my old 05 zx10r with akra evo, pc3, race cam, head gasket, ignition module, this run was baseline too before new mapping for headgasket and cam, the old 10r got 163 in the end with those mods.

For those that were interested in the Racefit growlers, there was one of our local magazines that fitted one to a 08 10r and gained 10hp.

The only thing I wasnt happy about is the dips at 8000rpm and 9500rpm. Not sure if this is an exhaust characteristic or if its the secondaries, which i have removed. May put them back in when i go back to the dyno to have a look if it smoothes that area out. The AF line was nice and flat, and the Wideband O2 sensor running with the AFR was .1 richer than the Dynojets sniffer. We think this may be because the AFRs sensor is in a better position for readings and not sniffing down the end of the can. The AFR sensor is located in the link pipe next to the rear set.

I wish the Motty was mass produced and sold here in the states. It is even better than the Bazzaz. Any pix of the Motty install? Plug and play or cut and splice as I fear?

I agree, those dips are ugly and I hope not a characteristic of the Akra pipe as I have that same pipe but have not had it on the dyno yet.

Very interesting thread. Keep us updated PLEASE!

According to the manual (downloadable from their website), you have to splice it into the wiring harness. It is available for purchase off their website, so no reason you can't get one here in the States, just not from a local supplier. Looks like the price is at 460 euros which works out to around $675.50 US with current exchange rates. plus whatever shipping might be. You can buy the lambda sensor locally from any autoparts store. They even provide the part #s in their FAQ.

Honestly, after skimming through the manual, it seems to be a hell of a piece of tuning kit and at a great price as compared to the Bazazz unit with optional AFR or a PCIII that can't do tuning on the fly even with their option AFR stuff. Install would be more difficult since it does require splicing into the bikes existing harness but the results look to be well worth the effort. I might have to invest in a Motty unit now...

Couple of notes from the manual, this unit also has built in data logging, 2 map selections and doesn't require extra hardware to control those options while riding. It is all controlled via gear position and the throttle with ignition on and before the engine is started. Awesome stuff.

For some reason I thought there was an AFR unit available for the Power Commander, I guess there isn't tho as I was just looking thru the site and do not see one.

DJ I believe have the wideband datalogger, but you have to interpolate the data where Bazzaz does that and then the Bazzaz makes suggestions.

But this Motty doesnt just make suggestions, but instead makes the hard changes as I understand it.

Cut and splice harness though is not for me.

Maybe one could get a harness off a totaled bike and make personal plug and play for Motty. I think thats over my abilities though. :sad:

That is exactly what it does. Excerpt from their install manual:

4.1.3. Self mapping
The most important feature of the AFR Tuner is the capability to combine the wideband air-fuel ratio measurement with the fuel injector control and merge the two into a closed loop, self mapping fuel injection system. The biggest advantage of the automatic mapping is that the fueling can always be optimal even if new modifications are made to the motorcycle or slow changes take place like air filter clogging or engine wear.

You do realize those are STD #'s don't you? They are fine for tuning to see gains as long as temp. and humidity don't change much.

I would like to see the SAE (corrected) #'s.

Please, someone correct me if I am wrong. I would love to thing I will be able to tune 176rwhp out of my 10!

Ill see if I can get a print out with the SAEs next time Im there.

Yes it is cut and splice, not that difficult though as all the connections are made at the start of the ECU harness. The unit came with a simple model specific wiring harness guide that made it easy, you just need someone who knows how to solder if you dont yourself.

I will try and get some pixs up of the unit, connections, and lambda sensor when I get time.

Ill put the secondaries back in and see what effect they have on the bike. Im interesed to see if its the them or the exhaust thats causing the dips in the curve.

Im going to say that 176 std is going to equate to roughly 164 sae.

Just got back from the dyno again.

First map is baseline of 08 ZX10R with 1000kms , 5th gear pull, bone stock vs. same bike with 3500kms, 6th gear pull, with Akra evo system and Motty AFR running 13.2afr. This map is in SAE for the person requesting it.

Second map is 08 ZX10R with Akra Evo system with Motty AFR running 12.8afr vs 08 ZX10R with M4 full exhaust with PC3. This map is in STD.

Also forgot to get the map but the secondaries reinstalled did not effect the dips in the line, they picked up a little power down low, but traded it off for up top. I now think the dips are being highlighted by the exhaust, especially when compared to the M4 system map. The M4 system has a smoother power spread where as the Akra is more peaky, the Akra design looks like it is going for all out power. We did pick up a little more power running it at 12.8 vs 13.2.

Such a nice set-up.... I wonder if it will play well with a forced induction motor...?

...that dip is nasty though, and it looks to be a result of either the A/F tuner or the Akra system. If it was down in the 3k-5k range it wouldn't be such a big deal... but up in the meat of the midrange like that is not acceptable in my opinion. Have you had any luck figuring out what's causing it? BTW, I noticed that my 06 picked up more MPH consistently when I was running 12.5:1 as opposed to my 13.0:1. The dyno showed almost no difference in power, but it was worth 1-2 more mph when it was actually running. No small difference there, really. :)

Cheers


PS Just re-read: did you have the A/F tuner on there with the M4 system too, or just with the Akra system?

The M4 system was on another 08 10r running a PC3.

Im making a guess that the dips may be a characteristic of the 08 10rs, as the AF line was fairly smooth, looks like the Akra is really highlighting them, where as the M4 seems to have dulled them down a bit, but there still slightly there. I guess the trade off is for the extra torque and hp. Will be good to see when other members post up with Akra runs and see if it is indeed a trend.

In the end I set the AFR to run at 13.2 up until 50% throttle and 6000rpm from there it drops to 12.8. Probably could make it better with more time, it would be great to work out all the differant AFRs vs throttle and RPM, but ive had enough of dynos for now. Another interesting thing was that the bike was still pulling 170hp at 80% throttle, the dynotech was suprised by that one.

Not to worried about the dips because there at 100% throttle, I suppose I should say I havent noticed them being a problem yet, the bike is still silky smooth getting on the gas out of corners. Im only at 100% on the straights, more of an issue keeping the front end down.

From Akra's website, stock versus their Race/Evo system. I never automatically believe what they have on their website though. May not be nothing compared to what the rest of us actually have, but here it is anyway.

I agree, that dip high in the tourqe curve in the previous graph is ugly, and makes me want to get my bike on the dyno for a baseline run to see if it is there and is being caused by the Akra or something else.

Just after I posted I went and checked out their website. Would be nice if my line looked like theirs. Was thinking I should experiment with differant afr settings at those rpm points to see if I can get an improvement.

I've got one of these Motty's on the way for my 05 :)

jon & phill @ racefit is cutting out the valve on my stock headers replacing with a straight thru ti section and putting a plug for the lambda in...

essentially going to make it into a full system/growler setup

:thumbsup:

the 2ndry flies are full open by 6000-6500rpms so i doubt that they are causing a issue at 8000-8500rpms, good 3's on the dyno thgh bro
