Re: The BIG Dynojet PowerCommander V and AutoTune Q&A topic

Reviving an old thread to ask a question about the AT-200 autotune module. Mine has two holes in the top, aparantly to allow access to something? One hole is plugged, the other isn't. Do I need to leave that open for any reason?

Thanks.

Lower RH corner there are two holes next to each other. The one on the left is open. I can see inside the unit.

Cool - thanks. I don't know what the other hole is for, but the button seems to be for the O2 sensor diagnostics...

Hmmm! Thanks, it appears I'm missing a button.

There should be a LED light in that spot. That light comes on when the unit gets power. Yours appears to be missing.

Thanks. If the AT module works, I'll just seal the hole and roll like that. I hate returning things from an overseas APO.

So if I want to just use the AT200 with stock headers, I still have to have the bung welded on? The AT sensor doesn't replace a Yamaha sensor? Is the AT300 worth the extra money and time?

After the AT does its thing and you get the desired maps is there a reason to keep it installed?

Bike is basically stock but does have one of Anthony's early flashes.

You will need the AT bung welded on. I would suggest the 200, and for a stock bike probably not use the 300. You can build two maps if you like, performance and fuel economy and then use them at will.

Thanks T.

I know you can add a switch to the pcv to use more than one map, but how does that play with S and T mode? Do you then really have 4 maps or do you do your performance and Eco mode in S?

In my experience you will get a bigger difference if you keep it in S or T more often than not. If you go back and forth your AT will start to pick up the ECU differences and start to make some changes (over many miles, not in five minutes) It will also depend if you developed the map in S, or in T... It will then be highlighted more in the one it was developed in. We develop all our maps in S and then the ECU will tone it down with the use of T. Some of these differences we've seen over the years ARE differences, but many of them are small and very few would 'feel' or even see the difference on the maps.
There is another layer of "vanilla" to the story. You will see/feel these benefits much more with a bike that has most of not all the bolt on goodies..... When you develop the PCV&AT on a stock bike you will and probably see differences on the PC screen with the AT out put, but probably not on the bike. The PCV&AT will help some of the specific fuel areas on the stock bike though, and you will feel that.. Its just not nearly as pronounced as a 'hot rod' bike.........

I just found this thread.

I have a question for all you guys. I'm looking for a bit more power out of my 2011 ST. I have the ecu flashed by AC (errmm the agressive map in sport mode where the throttle ramps up faster than you are actually twisting it), clutch basket from Karson (thanks man!), and tb's and CO set as per this site, staintune pipe, ran mostly without the baffle, and oem air filter.

How much money would I need to spend to get these gains? Do I need the headers, or could I simpy chop the cat out and call it done? (my acd plate would not fit, unless I extended the studs etc etc).
What are the real power gains of these mods? I saw the dyno sheet on one of the pages and read that it's making 107 foot pounds? or am I reading wrong? The tenere comes with roughly 75 foot pounds (don't quote me), is that a realistic gain, or am I a complete numpty and reading it all wrong...

Ideally I would love the bike to run like it did in California at sea level...you know that feeling when you crank it open in first, and the handlebar knocks your teeth out :D

and yes, I maybe looking for a winter project on the big girl.
your opinion and knowledge, are appreciated, as always

Thanks again, not looking for big gains. Was hoping to just smooth out the throttle. The on-off at lower rpms. I am sure this could be done with just the pcv but I haven't been bold enough to fiddle with it.


I am running the stock map from PC. Anybody have better maps for a stock bike?

For you, the AT would probably be your best bet..... so you can see what is going on and change it for your needs / feel....... .

Re: The BIG Dynojet PowerCommander V and AutoTune Q&A topic

For anyone who is running the O2 optimizers and Arrow headers, what have you found to be the best setting to smooth out the surging?

Cannot help with Power Commander, but the recent ECU Map I had developed on the Dyno sorted it, so it can most definitely be fixed 100%, I can now hold any rpm, 1500 / 1600 / 1700 or whatever as well as pull away smoothly from under 2,000rpm in top gear. It did seem to take a long time for the guy to sort the surge out, almost as long as it took to do the other 99% of the mapping.


To Answer Greg the Pole, I think Arrow headers are needed to get significant power, this is what I have for my bike (Arrows + Flash) Vs a stock bike with no mods:



You can see the huge top end gain with more power at 6k than the stock bike makes at its 7.5k peak, also the curve starts dropping off on the stock motor at 6k and I always found it felt a bit wheezy up top in stock trim, as soon as the headers went on (even before flash) I instantly felt it was much keener to rev out and pulls hard al the way up to (and beyond) the redline.

thanks Rasher,
so headers, and a PCV would be the way to go to achieve the above gains

Just finished the Romney Rally with the "full package" of headers, can, PCV, autotune, ECU flash, and S-T maps that have been refined by others over the last few years.

Other than I would be more comfortable with a quieter sound in the woods, I am very pleased with how CLEAN the bike runs in both modes. It's very refined, in my opinion. And just feeeeeels like it is fueled perfectly.

Sure, it makes more power than it did. But for me that is not the best thing about the mods. If those magazine dudes would use my bike in the comparisons, it probably would still come in the same pecking order, but with far fewer insults. Cuz it is very well sorted, at this point. I'm actually done.

Yea, I said it. Lol
(Oops, I just remembered our good buddy in Florida just shipped me the Tenere trailer hitch. If I ever get back home, I might put it on and go tow something)

Yep ::008::

I am not all that knowledgeable on the various Power Commander modules as I had the whole lot sorted via flash, but was told that there were some good gains from altering the ignition maps as well, also so if you can find a bolt on to do this (and a skilled tuner so as to avoid piston meltdown) a bit more can be eeked out.

I think Tabasco is the man for the Power Commander stuff.
