Well, The search for some ecu tuning has made my brain hurt and my dyno run has me scared to really hit 5000 rpm let alone any higher due to the A/F numbers I was getting. So, I contacted vallejo buell and they have some PC's left and will throw one on my bike. Is there anything I should be aware of or look out for?

Yeah,

I am not so sure that they work correctly on xb's. Some say you can use them with the X1 map, but Dynojet is not selling them for xb's. The real issue is probably the oxygen sensor and closed loop mode. If the PC adds fuel, the oxygen sensor will feed back to the ECM that the mixture is over-rich in closed loop mode and the ECM will adjust the Adaptive Fuel Value (AFV) down to get the mixture back to stock.

Techlusion now sells a TFI unit that simply connects between the stock oxygen sensor and also the fuel injectors. As such it is able to fool the ECM into thinking the mixture is leaner than it really is. It then provides three levels of adjustment for fuel, pilot, needle, and main jet equivilents. The adjustment is simply done by turning a potentiometer for each range setting.

I put one on my xb12 and I am positive it runs better now and has more hp. Unfortunately I have not had it dyno tuned so I don't know how spot on it is with the default settings, but you would know because your tuner could set it while doing the dynos.

The only thing the TFI does not have that the PC has is spark advance maps, but if you ask me the xb stock ECM has about all the advance you can run on pump gas.

I think Dave at Appleton Buell was ordering some. Also Al at American Sport Bike should be able to get you one. They are both sponsors on this site and you can get contact info on the banners.

BTW, I think the price is lower than a PCII or PCIII and you don't have to change the oxygen sensor.

The PCIII has been discontinued for the X1 & S3 models, and they never got around to making one for the XB. If you can find one they do work to an extent, but we found that ours would seem to lose it's fill every so often and have to be re-set again. We gave up in the end!

The new TFi unit is very good, and cheaper: )

I should have the Techlusion boxes in a couple weeks.
Price should be about 250.00 before the 10% Badweb discount!

If the techlusion works by making the ecu think its running lean, then shouldn't my ecu already correct if it is running super lean normally?
Good to know about the pcIII needing to be reset. not too hip on that idea.
Oh and can the TFi unit be used on the proseries ecu. Cuz thats all I have.

uhhh not really sure if it worked. Kinda. Anybody got a better idea of how to post this. Does kinko's have scanners? maybe I'll try there and try to post the origional.
Anyways the place I got it dyno'd at says I want to get the CO numbers at around 3.5. The 1.4 and 1.9 are way lean.

amazing, some day I am going to have to figure out how you did that.
So, anyone have any comments about the curve or any of the numbers ?

For the mods you have, the curves look right but the numbers seem far off...Its showing you having a peak HP of 58.9 and torque of 56.7, unless this is a "unhappy" dyno.

I am thinking there may be something else that is the problem but without actually seeing the bike and hearing it run or ride I couldn't begin to guess.

when I brought it in they said not to expect the huge numbers that I have seen from dynojet results and all. Then some blah blah ablah about real hp numbers from their dyno which I immediately tuned out.
http://www.factorypro.com/
here is a link to them and their info on their dyno.
Anyways, I figured the numbers of hp and tq weren't too important, but the fuel ratio and the graph ranges were.
Just need to get that lean problem fixed.

Thanks for the link, I did some comparisons of other bikes and your numbers seem to fall in line wiht the differences. Like I said the Curves looked right but the numbers didn't. I am still thinking perhaps there is something wrong for you to be running that lean.
