PowerCommander in airbox

I've had mine in the airbox before but re-routed it due to the inability to load new maps quickly.

Well its mostly street so wont be changing maps once it been tuned on the dyno with the new airbox.

Anything to to consider when doing it? Other than it not falling of and getting sucked into the engine. Would it be an option to fit other electronics in there? Or would it make some kind of turbulence that would be bad?

One thing to consider is that is taking up space that air would be so you would have less volume. I"m sure it's not really going to make much of a difference, but still.

Changing your maps would be a pain unless you had a connector routed to outside of the box. Also you will have wires going in and out of the box to connect in which would risk creating a leak in the box.

It would just be much easier to relocate to somewhere else where you can get to it. I always thought it would be cool to mount in on the dash so you can see it and watch the rev LEDs light up and know that it's working and have super easy access to it.

Should have mentioned Im fitting the T1 airbox, so there should be plenty of volume, and access wouldnt be THAT difficult, just lifting the tank.

Good point about the wiring needing a seal.

I guess my main concern would be having the PC3 misted with oil everytime your crankcase breather tube sends some overflow mist. After a while all that oil mist will start to seep into the cracks and buttons of the PC and potentially make it not function.

You wouldn't put your ECU in your airbox would you? Why do it with the other computer on your bike? I mounted mine on the side of the framespar left open after removing the side mount radiators. I am considering relocating my CDI unit on the opposite side frame spar right now FWIW.

FWIW and or FYI... Thorsten is the Man who did this... as usual He's the First that I know of... and it's the ECU and stuff, I'm pretty sure it's NOT the Power Commander. Anyhow, YOU can find the info.\Pictures on Thorsten's Web-Site!:rockon :clapper

One last thing.... The Power Commander is one thing I Also would NOT install in said AirBox....

OH Yeah,.. He "Thorsten" also did this Running the ECU His "Dumby Fuel Cell" so it's extra Huge AirBox NOT just your normal everyday runt of large AirBox

Wait a minute. Did you just ask if you should install your PC IN THE AIRBOX?!:woot::wacky

it's best to keep things out of the airbox. your coolant expansion tank for your front mounts can be put anywhere on the bike and doesn't need to be nearly as large as the oem unit. i use a honey bear at the moment and it works great. you can put it on the right side of the bike behind the front rad, and leave the left side open for electronics.


but really... why not just put it in the tail where it belongs?

Well Ive spend the last month reading just about everything on Durbahns website because Ive got nothing else to do.
And he speaks of 2 things, lowering the weight, and mass centralization, so I just though "why not" - Ive got about a month or two of vacation when I get home, with no weather to allow riding so might as well tear it apart.

so your 3oz power commander is going to make your bike awesome by moving from behind the rear axle to between the axles? you aren't even putting it lower by locating it in the airbox.


at this point it seems you're looking more for tinkering than you are for making a substantial change to your bike.

Well excuse me from wanting to mod my bike and clean up the tail.

Im sure no one else has ever done a mod to their bike, that didnt make any real difference, but did it anyway...

Hey LKHanberg,

Here's a Great TIP for You, Give Him "wilbbly" the 1 figure salute, off the bar ALL Day long Reply.... somehow It just Feels like the Right thing to do!

Glad YOU found the picture I was telling You about.:rockon

Peace Jeff

The airbox is subject to some significant vibration (aka intake honk) as those big cylinders gulp air. Electronics typically dislike vibration... :twocents

LKHanberg said:

Yeah well asking here beats trial-and-error resulting in having to buy new electronics...

Thanks for the useful answers, apparently I wont be doing this.

And Heist, next time I get an idea Ill just jump into it and start a thread asking what went wrong after I ruined my bike like all you guys do. Oh wait, you dont, you use other people's opinions and experiences....

Edit: Just found this photo on Durbahn's website...

Well, Durban is an interesting character - I have no idea why he put the coolant expansion bottle in intake tract, let alone next to the velocity stacks?

Still enough, I've never heard of mounting a PC or Bazzazz - let alone any electronics save for some kind of MAF sensor inside the airbox.

Off the top of the head, I could think about 5 things very bad and maybe only 1 good thing (increased airflow cooling) but the immediately offset by radiated heating from the lump of a mill sitting 3 inches below it.

Hello Heist,

That is NOT the coolant expansion bottle... That is the mod. catch can for the Engine OIL breather... Which by the way... I don't know why anyone would do this either...?
As I have mine just blowing into the AirBox!:rockon Plus,.. This picture is NOT the picture I was talking about, now that I've had sometime to look at it. As a matter of fact... I'm not so sure this is even of Thorsten's RC51!...

Hey LKHanberg
I'll go and find the picture\INFO. I was talking about..

Peace Jeff

Thanks a lot, at least now I dont feel quite as stupid Knew Id seen it somewhere, but just couldnt find it. Again, thanks.

Nice find Mav! Quite the media reference bank you're storing in your head there.

From this pic, its unclear if he is going to have any oil mist go into the airbox and if he is going to be running a std tank or a below the seat fuel cell with dummy cover over the airbox/ecu/cdi.
