NOTE TO ALL:::2008s are different, tuning the fueling is different than 2009+ with IBEAT (TPS adjustments are the same process though- with all mikuni efi)--
I'd set the WOT to 100.2% by adjusting the hardstop on the throttle boddy and accepting the new position at closed throttle. Then verify your FB1 setting is between 107-96- if not change to 100 (per instructions). Write down all your settings before and after. I thought that PDF was on here somewhere but if its not I'll try to post it. Its on another computer right now...
Power-Up and Feedback Proceedures for the 2008 (from husky). Here's a paste and cut of the text....
FEEDBACK ADJUSTMENT PROCEDURE
The FB (Feedback Adjustment) function is used to adjust the fuel injection, basing on LAMBDA
sensor output signal. Changing the Feedback Adjustment value, the engine A/F mixture control parameters
in the ECU will automatically change, and consequentially the exhaust gas value too.
1) To check the existing FeedBack Adjustment value it is necessary to employ iBeat Diagnosis Tool
(Husqvarna code 8000A9634); if you need to operate a change in the Feedback Adjustment value,
you have to connect the LAMBDA sensor to the wiring harness. In case the lambda sensor has been
removed, it is necessary to electrically reconnect it.
Important! if the original wiring harness was replaced by the RACING harness (Husqvarna code
8000B0146), in order to operate the Feedback adjustment it is necessary to apply the original
harness and connect it to the ECU, to the injection system sensors (lambda sensor, throttle position,
engine temperature sensor) and to the contact key and battery.
2) Connect the diagnosis cable to the diagnosis connector (it is the 6 pin connector with cap, placed
behind the front light cover)
3) Turn to key-on, without starting the engine.
4) Start iBeat Diagnosis software program, and click on button on the main page (it is the red
circled button in the Picture No.1). The Feedback Adjustment window will appear according to

5) Register the Adjusting Point (109.5 in No.1 cell - Picture No.1)
In case the shown value is higher than 107%, or less than 96%, please adjust it to 100%.
6) To regulate the Adjusting Value, start the engine and wait until LAMBDA sensor starts to work.
Important: when feedback adjustment function is permitted, Feedback Adjustment Value moves
from 100% and on the display this window will appear:
7) click on the up/down arrow in order to reach 100% feedback Adjust value as shown below in
the Picture No. 2
Picture No. 2
8) Click on OK button to confirm the new adjusted value, then close the feedback adjustment window.
