Cheap & Easy Tunning on my 08 XB12R

It's simply too good to be true... :)
No mods to fuel injection, other than the gadget? So, OEM fuel maps.
Please, say more about tuning process. Just turn screw/test/turn screw/test...?
Smooth response @ throttle changes and @ cruise?
 
OK, I'm not an expert on tuning exhaust systems, but I remember a few things from gas dynamics classes back in college. First thing is that there is no such thing as "negative pressure." Pulling on a gas is less possible than pushing on a rope. Second expanding a pipe actually slows the flow. A venturi demonstrates the opposite effect. The tuning pertains to the relationship between the engine frequency (RPMs), the accoustic resonance frequency of the pipe, and trying to maximize the effeciency of flow through the system. If I remember right from my XB maintenance manual, the interactive exhaust system switches from long to short and back to long as the rpms climb. Ultimately, you're limited by the size of your pump and atmospheric pressure. Therefore, the only answer is that you need a blower. :)
 
aptbldr,
correct, no mods to fuel injection and stock (OEM) fuel maps. basically all you are doing is telling the ecm that the exhaust has no unburnt fuel (so the engine is not running too rich) and the IAT is telling it that it needs more fuel. by turning the screw you are just adding more fuel to your stock map by percentages. all this thing does is compensate for mods that will make your bike run lean, like K&N & exhaust mods. so to answer your question; yes, very smooth at all throttle positions and acceleration is very responsive weather light or heavy. Hope this helped. ;)

jeff m,
I think the interactive exhaust valve is open under heavy acceleration at low rpm, closed at mid range, open again at high rpm. & yes, very limited by the size of your pump! but that's what makes mods so much fun; trying to get all you can get out of that pump (without hurting it of course) :D and no i don't need a blower, i would hurt myself! lol. long story short: I am very pleased with the results & performance thus far!:D:D

I have a 07 XB12Ss with Jardine exhaust with adustments in Dyno bench. Yesterday I mounted Dyno Boost Performance Chip and did a test trip without any adjustments on the device.

The engine was a bit jumpy at low rpm, but there was significantly more power when the rpm increased, even at high rpm. :D

The magic device was pretty easy to install, even for a novice as me. But as always novices runs into some problems and I need some advice from the pros.

I followed the instructions and cut the IAT signal wire and contacted the purple wires to the two ends.
Now the Check Engine Lamps is red constantly when I drive.[confused]

In one of your previous posts you wrote:
"spliced it into the o2 sensor wire & the IAT sensor wire under the air box (that was the easiest location to get to) then gave it a power supply on & off with ignition"

Did you also cut the IAT wires and removed the IAT sensor?

Right now I have mounted the device directly to the battery and the device always is on. Can you explain how/where you mounted the device to turn it on/off with the ingnition key?

I doubt he did, since cutting the IAT wire will throw an engine code (as you've now seen). The ECM needs to have a way to know what temperature the ambient air is, and you've just removed it's only method. I would suggest you return your IAT to function immediately, and simply splice in your new toy, instead of cutting the IAT wire and connecting the two.

You can connect it with an add-a-fuse to an appropriate fuse in the fuse block. Or you can power it via relay with an appropriate switch.

I would advise all of you to reconsider purchasing this item. There is no "magic" tuning device. Your best options are datalogging with a WB O2 and tuning maps individually. It's a permanent method, requires little technical skill, and a lot of bike hours (which, let's be honest, is a good thing).
 
Thanks to theoctopus for the tips

Dear xoptimizedrsx
I do not know how to understand your feedback.
Do you really mean that the things I write is a lie and that my experiences is all wrong?
I bought this device as a customer and has no commercial interest in the product or supplier. My only wish is that the device will function according to the commercial and I can confirm that it works quite good and as the commercial says after running approx. 250 km.

Have you tested this product since you are so firm in your statements?
 
Bump for updates on this?

Haven't had any luck with tunerpro, or ecm droid.
 
Hello I have a doubt about installing the dyno that you installed your. Your you might send images wherefrom the cables go it to install in my buell xb12 firebolt. that the image is the original one of which you have your to be following the process. Thank you from Chile.

Hola Antonio. Bienvenidos a BuellXB. Estas cosas no funcionan muy bien para Buells. Hacen mas daño que bueno. En mi opinion, las personas que dicen que estas cosas mejoran sus Buells quieren ver mas resultados de los que hay en realidad. Debes usar ECMSpy si su Buell es 2003-2007, o TunerPro si su Buell es 2003-2010.

(Lo siento para mi español, no es mi primera lengua.)
 
Hi Antonio. Welcome to BuellXB. These items don't work very well for Buells. They do more damage than good. In my opinion, the people who say that these items improve their Buells are looking for more results than there are in reality. You should use ECMSpy if your Buell is 2003-2007, or TunerPro if your Buell is 2003-2010.

(I'm sorry for my Spanish, it's not my first language.)
