Ok lets see if I can give written instructions on how to programme two levers for individual engines and use the same levers for reverse thrust for the Saitek throttle quadrant. A registered copy of FSUIPC is required and used for all axis controls i.e. joystick etc is disabled in FS.
Open FSUIPC at the Axis Assign Tab and press the Rescan Button until the two boxes marked Joy# and Axis# are empty and Move Lever is displayed
Move the first lever and Joy# 1 and Z Axiz# will be displayed
Under the section marked Type Of Action Required enable Send Direct To FSUIPC Calibration
Find Throttle 1 in the drop down list directly underneath and tick the box at the side to enable it
Rescan again and do the same with the second lever but this time Joy#1 and U Axis# will be displayed and so enable Throttle 2 in the drop down
It's as simple as that for assigning the levers but they now need calibrating and so the next step is as follows;
Open the Joystick Calibration Tab in FSUIPC and step to the Seperate Throttles Per Engine section where the 4 sections within for throttles will be displaying "Axis not processed". Of course we are only interested in Throttles 1 & 2 so the next step is to calibrate Throttle 1.
There are several boxes which will indicate IN and OUT readings. There is no need for a detailed explanation here but the numbers in brackets are mine.... yours may be different.
Set the lever to 25% on the quadrant (8832) and press the Set button which will enable three more set buttons to the right, Reverse, Idle and Max corresponding IN OUT boxes.
Press the Idle button twice and the boxes underneath will be the same as the two on the left (8832). This is, as indicated, the Idle point.
Now move the lever to 100% ie max thrust and the left boxes will indicate a positive number (16383) and don't worry if they are not exactly the same. Press the Max button to transfer this number to the Max box.
Next is Reverse thrust so move the lever to 0% and transfer what is now a negative number to the Reverse box using the Reverse button.
You now have individual throttle control for each engine where 25% on the quadrant is idle thrust along with individual reversers at 0%.
For the techies amongst you there are detailed explanations available amongst the comprehensive documentation provided with FSUIPC and for those of you are interested I use the third lever as a gear lever.
I hope that this has been some help and do apologise for the lack of screen shots..... the resolution wasn't good enough if I kept them to a manageable size.
