Fan after turnoff

[MTech14]

Just curious, how hot does the xb12r need to be for the fan to turn off AFTER you turn the bike off. I have a 09 buell, and shortly after riding, I can hear the fan running when I'm going faster than 15, and turning off when I come to a stop, but the fan has NEVER turned on after I've shut the bike off. Anything to worry about? No CEL or codes, and I know the fans running.

Thanks

It's the "speed based fan control" and I hate it.

You can turn that function off and find your specific temp on/off settings (and change them too) using tuning software like ECMDroid, ECMSpy, TunerPro, using a cable or Buelltooth (wireless) connection.

I agree. Seems a little backwards that the fan runs when the bikes getting hit with moving air, and turns off when the bike is idle and not getting airflow. But any idea why my fan never turns on after shutoff?

I'm with Cooter on this one.
Makes no sense to have the fan ONLY running while the bike is moving and air is already cooling the engine. I think it's much more beneficial, for the engine, to have the fan run when the bike is static. Yeah, it's not the coolest sound in the world when you shut your bike down and the fan kicks on, but if you're worried about that... ...don't ride a bike that has the rear cylinder crammed into the rear of the frame in order to house the fuel in said frame.
Anyway, I'm getting off topic. My bike is an 07 and I've never changed the fan logic. If my fan doesn't come on when I shut the bike down after a long ride I think something is wrong.
BTW for anyone reading this, adding a RSS, from the comfort kit, while drastically reduce how often the fan kicks on.

 

[MTech14]

So basically, if I drive 30 miles on the highway going 80 mph, and shut the bike off shortly after, and the fan doesn't come on, something is potentially wrong?

 

[MTech14]

And if so, what setting am I looking for in ecmspy to make my fan turn on after turning the bike off?

 

[Cooter]

Just let it do its thing.

 

[Chicknstripn]

No sir.
You're fan/engine temp sensor is programmed differently.
My bike is an 07, and since the first day I rode it I've understood the fan kicks on when the engine is at a specific temp. For me it's after the key is off. Sometimes, if it's really hot out and I'm really flogging the thing it will come on during the ride. Your bike is an 09 so the fan functions differently.
Google search "buell xb fan function" or "buell xb fan programming" to get some more info.
As Cooter stated, it seems your fan function is triggered by speed more than temp. But to be honest I'm no expert.
So hopefully an ECM guru will chime in. Until then do some research, it can't hurt.

 

[MTech14]

Alright, thanks everyone. The way I see it is, fan settings haven't been messed with, and it clearly works when riding the bike, so the bike must not be getting hot enough to require it to run when off. Either way, its working, so I'm not gonna worry about it. Thanks for the help as always!!!

That is incorrect, that is stock for 09. Buell/EBR changed to that fan logic in 09. I would turn off the speed based fan control.

 

[Chicknstripn]

AZ is one of those ECM gurus I mentioned.
I'd follow his advice.

correct as usual cole. that 2008-2010 fan logic is annoying as hell. and with RSS installed the "fan activation at speed" becomes a moot point. guy who initiated this thread ended it with "i'm not going to worry about it" so, as usual, our recommendations will fall on deaf ears.

 

[MTech14]

No, don't worry, recommendations will be listened to. Just wasn't going to worry about it too much, because as Cooter said, just let it do its thing. I'll be deactivating the speed based fan control today, and definitely looking for a RSS. Thank you for the info everyone!

Here is the one I installed on my 06 Uly, and it did reduce fan on time, by lowering the head temp, But what really made a difference was running a race ECM.

Here are some interesting #s to share with the group.

OK ... got some numbers ... 85 degrees outside ... 7 mile ride around my neighborhood. Last 1 mile was 50MPH of open air before shutting off bike and taking temps.

NO SCOOP:

Right Side Front Cylinder: 263
Left Side Front Cylinder: 260
Right Side Rear Cylinder: 288
Left Side Rear Cylinder: 270

Fan Came on when stopped. Fan turned off with Right Side Rear Cylinder at 265.

R. Crins RSS installed:

Right Side Front Cylinder: 271
Left Side Front Cylinder: 270
Right Side Rear Cylinder: 276
Left Side Rear Cylinder: 270

Fan Came on when stopped. Fan turned off with Right Side Rear Cylinder at 265.

Note:

Bike was warmed up about minute before riding with no scoop. I also had more stop and go traffic the no scoop ride ... got caught at several lights.

I put RSS on and then took the ride so bike was warm. However, I only stopped at one light on this ride ... rest was 3-4000 RPM ...

Riding aggressiveness was same on both trips.


All temps take with IR thermometer pointed at cooling fins at the highest point visible on the cylinder.

 

[AZmidget91]

This simple test makes it seem like RSS is not worth it .... this is not what I expected. Also not sure why but front Cylinder actually ran warmer with scoop installed.

The RSS didn't come in a "cooler engine temperature kit" It came in the "rider comfort kit" air cooled engines are designed to be in the open air, or have a tightly fitting shroud. The RSS really just keeps the heat off your leg, and directs it towards the engine.

 

[TPEHAK]

It also maintains better look.

Thank you AZmidget , I was in a hurry and posted the wrong kit , :black_eyed:
And for the record the test was not my doing found it on the net, I have always installed the kit on my XBs just for piece of mind if any thing.

So what you posted is not from first hand personal experience???? How much other "information" are you simply doing a copy and paste job on? Do everyone a favor and let us know when you're doing that and what your source is. That way the info you post can be ligitamized, investigates, researched... whatever you want to call it.

I will say this much about this whole fan related post, my fan does not run as much as it did prior to me installing the right side scoop from the buell comfort kit. Take that for what it's worth. That's my personal experience having owned the same heep of buell for over ten years. 5 of those years were without the RSS.

I'm pretty positive AZMidget runs the RSS. I would have heckled him, if I wouldnt have seen it on his bike.... and his bike is pretty damn dialed!

I'd never run an XB without the RSS, but every one I've owned did not come with one from the previous owner. And I'm assuming these bike probably lived in AZ all of their lives (some potentially for 10+ years). So, it probably doesnt hurt the bike without the RSS, but I'd rather spend the $$$ and buy a few degrees of heat away from the motor and my right leg (I also get the heat shield).


I do agree with you, about the fan being less active with the RSS in place. Maybe its placebo, but it sure seems like it doesnt run as much, especially at shutdown.

Chicknstripin, For what it is worth, pretty much all I have shared with the board is from first hand, from owning and living with bikes for over 45 years of working on all my bikes myself, could not afford to take them to the shop. I am a hands on bike owner. I dont understand why I am defending my self, LOL If you would like pm me ,That goes for any board member , I will tell you my life story with all my bikes that I have rebuilt and owned starting with my 1963 Greeves Griffin 250 , 2 cycle with a leading link front end my first dirt bike.. I enjoy bike talk!!
