I can haz auto tune!
 

Turned up today, however, because of college (and then karate) it's to late for me to fit it now, but shall fit it tomorrow and give it a blast and post back what its like!

Looking forward to the results. :sbike:

Personally, I try to avoid rolling around with other blokes, especially in my PJ's


:moon:

Ok then, I stand corrected.

Still dancing with another bloke, and in your PJ's.....:rotf[1]:

I do shotokan!

Only been doing it for a few weeks so im still only an ungraded white belt :P

But its fun and only picked up my Gi yesterday!

On the auto tune front...

It took me a couple of hours to install.
screwed in the lambda sensor which by the way, is stupidly long and gets fiddly to fit between the cylinder.

Fitting the rest was a doddle apart from finding a power source. They suggest using the tail light, but I didn't want to start removing cowling to get to the wiring. However, there are under the seat, 2 unused plugs, and one has a power supply that comes on with the ignition, so I cut that wire and used that.

Also plugged the AIS up, which is a shame cause I kinda liked the backfiring but nevermind...

What it doesn't state in the manual, is that when you plug the autotune into the PCV, you need to put the 2 supplied plugs into the empty plug sockets as the auto tune wont work otherwise!

Spent ages trying to work out why I wasn't getting a reading on my laptop from the sensor, and that was why. Soon as I plugged in the empty plug sockets, voila, I was getting a LIVE AFR reading on my laptop... pretty darn awesome.

AFR was set at 13.7 to 13.2, though recommended for performance is between 12.7 and 13.3 I believe, or something like that

Took the bike for a quick ride in the pouring rain... and well, it performs admirably!
Even with the custom map, there was still a small amount of surging. However, with the autotune connected...


None!



It rode like I was riding silky smooth, no jerking no lurching... that thing is incredible.

Just need to take it for a good ride, connect up my laptop again and accept the trim settings which will then allow it to get it even more spot on.

Possibly turn down the AFR too, need more powah!!

Nice to think though that when I add the stage 1 filter, it'll automatically adjust!

Nice one.

Once you have complied your custom fuel map please can you send me a copy so I can have a look at it.:errrr:

I'm not sure if it actually changes the map itself Kev, rather than adjust the fuelling to match the set AFR table.

Without the autotune, the PCV map adjusts the yamaha fuel map to whatever values are inputted by a percentage adding or removing fuel at that RPM and throttle opening.

Whereas with the autotune, it runs on the Air/fuel ratio set in the AFR table, like 13.7 and uses the wideband sensor to pick up the burn ratio on the exhaust, and then adjusts to suit.

You can see it working on the PCV software, if you open the throttle, the AFR will be all over the show as its adjusting. but once you hold the throttle steady, the AFR will read ~13.

Least I think thats how it works anyway Kev

so if I send you my map map, I believe id I'd just be sending you the original map that I put on there myself and not a corrected one by the autotune.

Correct me if Im wrong however.

Just looked up... I stand corrected!

Will send you in a few days time!

What a ball ache its being...

I loaded a map onto the PCV that best suited what I've got and it ran ok.
Now the auto tune just seems to be making it worse!

So I may just reset the fuel map and start from the beginning.

What afr have you added to the target table, can you copy and paste the table to the forum so i can have a look. You can only put a target afr in the high throttle openings on the later Xt's and just leave the rest on the table with zero's.

The surging on the 07-09 models will just confuse the autotune and make a dodgy map correction, also you must block off your AIS system as this will show an overly lean afr at part throttle as well.
