I need someone who owns a 2009 model of any XB model other than the Ulysses. I hate the fact that my '09 XT with comfort kit flash runs its fan 100% of the time, and asked the dealer to flash it back to pre-comfort kit. Anyway they can do that but they need a VIN from any 2009 model other than a Ulysses.. can't be from the X or XT model because their system will automatically pick the comfort kit flash as the latest available for that VIN. None of the other models got the retarded speed-based fan settings. Thanks in advance. | ||

Ebay or just change the model code in your VIN.
That is inaccurate. All 2008+ XB models can be re-flashed to get the new fan strategy. The 2010 models come from the factory with it. | ||

Never thought of just changing the model code from my VIN. I'll give that a shot. Thanks. I assume the VIN is broken down in either the service or owner's manual to tell me where the model information is? | ||

RTFM  http://www.buell.com/om/99474-09Y_en/file-2.asp#hd topic000654 But yea there is a 2009 Firebolt on ebay you might want to copy the VIN off of just in case. | ||

But yea there is a 2009 Firebolt on ebay you might want to copy the VIN off of just in case. That is the route that I would recommend. There's a check digit in each bikes VIN, and there's no guarantee that the check digit is the same for Uly #XXX as the check digit is for XB12Whatever #XXX. You may get lucky and they are, or you may meet extreme resistance when they say 'That's not a valid VIN!'... VIN's are such special things... 1313 | ||

Thanks Froggy. My Uly owner's manual is tucked away still in it's plastic wrapper. The same info is probably in the service manual, I've just never looked for that specifically. I'll see what I can get accomplished with that 12R VIN. | ||

took the Uly to the nearest dealer - had them reflash the ECM using the 2009 Firebolt VIN from ebay. The bike works exactly the same way it did before, with the same retarded fan logic that kicks on at operating temp and 15+ mph. | ||
| Arcticktm |
Is it possible you have another issue, like a faulty temp sensor? I don't recall anyone else saying their fan ran constantly after the reflash. | ||
| Froggy |
I hate to say it, but I knew this would happen. The new fan control logic is superior to the old style and helps keep the engine running cooler. Nothing defective. | ||

Arctick, there is no problem.. nothing to "fix". It's just my personal opinion that the most recent flash and it's fan logic puts a lot of unnecessary wear on the fan. I can ride in sub-freezing temperatures, and as soon as the bike reaches operating temperature the fan runs even though it's completely unnecessary. I mean I had to stuff a rag into the oil cooler so oil temps would get high enough to avoid condensation build-up, yet the fan still runs. Makes more sense to save the fan life for days like today.. 95-100* outside when I get stuck at a light on my way to work and the engine actually does need an increase in airflow to stay within a safe temperature range. Guess I'll leave it the way it is for now. | ||

I have to stuff the oil cooler even with the old style programming on my 06. The point of the new programming is to keep the engine temperature lower from the start so it is less likely to need to run the fan after shutdown. | ||
| Pkforbes87 |
That's why I wanted the old fan logic. Fan running after shutdown means a lot less wear and tear than the fan running for 100% of my >15mph miles. That XB engine doesn't need the fan to run as much as it does now. My X1, even with it's modified higher compression engine, has not once overheated when sitting in a reasonable amount of traffic or stoplights, etc. Yes, I realize the tube frame allows more airflow. In a variety of situations causing the engine to reach higher than normal operating temps, I've never seen oil temps on my X1 higher than 208. I don't have a way of measuring the exact head temps, but hooking up ECMspy ASAP after a ride has always shown the head temps to be around 310. Measured from the rear head on a bike with no cooling fan of any kind, I'm not worried. Now I do foresee times when the cooling fan on the XB models would be needed. Because the XB frame doesn't allow as much airflow, the fan is no doubt essential when in an urban environment with stoplights, traffic, low speeds, etc. Since the bike doesn't need the fan while traveling 80mph down the interstate, I would like the option of saving the fan for when it's really necessary. Neither one of us will change our minds Froggy. I understand your points, I just don't agree with them. Again, thanks for your advice. Guess I'll look into the newer tuning software that will let me mess with the '09 ECM as I don't think my current version of ECMspy will work with anything but DDFI 1. | ||
| Froggy |
I do understand your concerns. Airflow is an issue at speed on the XB, given that the frame blocks a lot of air that could be cooling down the rear cylinder and head. That is why even with the old fan programming, the fan would often kick on after a few minutes on the highway. The Uly tail section doesn't do much to help airflow either, hence part of the comfort kit was a revised fan duct. I am sure the operation can be reprogrammed in TunerPro. I just am not sure exactly how to do it, as I lack a DDFI3 XB to experiment on. Oh, and a fan is a hell of a lot cheaper to replace than a motor. 45k miles on my original fan on my 06. | ||

I had a new fan installed in December on my 08 and the latest flash done. The fan is always on from about 15 MPH up. Or it was until it died. 6 month service life for a fan seems pretty short especially since it snowed from December through April, then rained most of April. Wait that is only two and a half months of riding. With the new flash I think the bike runs hotter, if you ask my right leg! | ||
| Froggy |
Pk - I was just thinking about this, I recall a thread mentioning the XB12XP does not have the revised programming. Perhaps you can try a VIN off one of those? | ||
| Pkforbes87 |
alright, thanks for the idea. I'll try to track down an XP VIN and give it a shot. |
