Dobeck is assembling them now and will be ready next week according to them. They are taking orders now and expect to ship them out next week. The model number for Buell XB is 1045ST, which sells for $259. | ||

anyone know if it does anything different than the PCIII? | ||

Did you check out the dobeckperformance.com site. It explains what this unit does and how it differs from the competition. | ||

The techlusion box will only richin the fuel mixture. The new model is supposed to keep the check engine light from coming on. I have the techlusion 1040i box on my xb and it works fine, as long as you don't mind the check engine light coming on now and then. Techlusion boxes have just a few basic adjustments making them easy to set up. The new model is supposed to hook to the O2 sensor. The model I have does not.

I did now. | ||

Capt...With all due respect, knowing the importance of the check engine light, it would drive me absolutely insane if it kept coming on for no reason other than the DFO. Glad that isn't the case with my X1. | ||

The techlusion box will only richin the fuel mixture If that were the case, then how is the A/F ratio changed as diagrammed in their website? | ||

Unless they have changed the box significantly, you can only richen the mixture. It is pretty clear in the instructions that come with the techlusion. The check engine light, if it were to stay on it would bother me more. It is strange, as it only flashing now and then at speed. At idle, I never see it on. Hopefully they will get that bug worked out. However, there has been talk of this new box for at least the last 6 months. I'll believe it when I see it. Then I will likely buy one. I can always sell the 1040i box I have as that is the same one used on most harleys. | ||

Okay I'll bite. Why would I want one of these on my Xb12r with a race ECM? I'm curious! | ||

You would be able to flatten your fuel curve which "should" give more power unless the race ECM's fuel curve happens to be set up just right for your particular part combination. | ||

The model 1045ST is the new box for XB - I just ordered one. I can't say what the difference is between 1040i, if that unit indeed was designed for XB. | ||

Tatsu...Run your bike on a Dyno with exhaust analyzer. If you are not running lean, you don't need one but may want one to alter the power curve or get a few extra ponies. On my X1, I had a lean condition with either the Stock or Race ECM with the intake and exhaust mods I had done. The DFO corrected this and allowed the tuner to put more grunt in the low and mid RPM range which is where I ride most of the time. Could have added a few ponies to the top end at the expense of the low and mid range but that just wasn't my goal. IMHO, the DFO is a good thing to increase the life expectancy of your engine. There may be better ways to go if all you care about is a race oriented bike. | ||

I sometimes wonder why Buell even fitted a check engine light, like if there was a critical problem wouldn't we know about it? It cries "wolf" too often...mine's very close to being permanently disconnected, and the stored trouble codes are all that are really needed, and a lot more useful. | ||

Dcmortalcoil, The 1040i was not designed specifically for the xb. It will work, but will throw the check engine light on. The 1040i was designed for most other harley engines. Let us know when you receive the 1045st. Everytime I have inquired about it, I've been told they were not ready yet. | ||

How does the Techlusion deal with the closed loop and the learning portion of the Buell ecm? I thought that the learning part of the XB ecm would always try to return the fuel curve to ORIGINAL, so that if you add fuel with Techlusion, the XB computer re-learns and sets it back to original AFR. It seems to me that the only part of the fuel curve that the Techlusion will alter are those parts that are outside of the learning and closed loop portions, and the AFV (Adaptive Fuel Value) will also change in an effort to return the fuel curve to normal. Am I wrong? mikeyp | ||

There has been speculation about adding a potentiometer or something to that effect to the O-2 sensor... theoretically if you could change the voltage received from the O2 sensor you could fool the ECM into thinking that the bike is running the way the ECM wants it to. I think this is basically what the 1045st does. | ||

Just a little info from the techlusion site. Q: I hear your product only adds fuel. Some people say you need to remove fuel? A: It is true that our product only adds fuel. We designed it that way to keep it simple and affordable. Our belief is that in almost every situation, addition of fuel is what fuel injected bikes need. Fuel systems are mapped by the factory to be lean in cruise and everyday driving conditions in order to meet emission standards. If you decide to change your fuel system, most aftermarket exhaust systems tend to reduce back pressure, which leans out the fuel even more. There are a few exceptions to this, and one that comes to mind is the Honda CBR929/959 when the exhaust power valve is removed. Honda designed their engine specs around that feature (specifically the exhaust cam timing) and when you remove that valve, volumetric efficiency in the motor is lost causing a bottom end bog. You can mask that bog by pulling out fuel around that area, and for that, you may have to go to another product. However, our product performs well with all aftermarket exhausts. We keep in mind that the exhaust must at least match the flow of the stock system that is being removed or modified in order to maintain maximum volumetric efficiency. |
