1. shaft slot is vertical, carefully slide the connector onto the shaft without
twisting. Slide down to about 1/8” from the bushing of the pot.
2. Snug down the pot shaft clamping screw and look into the open end of the
pot connector. Make sure the slot is perpendicular to the split in the
connector as shown in Figure 28. If it is not, loosen the clamp screw a bit,
adjust with a small screwdriver, and retighten.
3. Next slide the pot bracket assembly through the hole in the rear chassis
plate and onto the steering shaft terminus. Install the pot bracket screws but
leave them a bit loose. With one hand grasping the pot connector use a
Philips screwdriver to slowly tighten the pot bracket screws. While doing this,
rotate pot connector back and forth to make sure it slides freely on the
steering shaft. When the pot bracket screws are tight, the connector should
still rotate on the pot shaft without binding. If it does not, loosen the bracket
screws and try again. This procedure is important to avoid side-loading the
pot. Side loading can wear out the pot bushing prematurely.
4. Finally, slide on the wire terminal connectors as shown in Figure 19. Do not
tighten the steering shaft clamp yet. The pot needs setup which is explained
in the following section.

STEERING POT SETUP - USB HD ULTRA
1. The pot is setup using the Windows Game Controllers calibration routine.
Reconnect all cables, making sure the ground cable is properly attached and
start the computer. Go to
Control Panel
and select
Game Controllers
from
the menu. The Game Controllers dialog box should appear showing the
ECCI HI-DEF USB
controller is connected. If this does not appear check
your connections.
2. Highlight the controller, and then click on the
Properties
button. Select the
Settings
tab and click on
Calibrate
. Leave the controls untouched to set
center point then
click a button
on the wheel.
3. A square calibration box will appear. The steering wheel will be recognized
here as the X-axis, moving the crosshair horizontally in the box. Click the
box next to
Display raw data.
Numbers will be displayed for the X-axis.
Leaving the steering wheel centered, rotate the pot connector until the
number displayed reads
510
+/- 10 points. Using a 3/32” hex key, tighten the
steering shaft clamping screw of the pot connector.
4. Move the wheel left and right, observing the numbers. Let the wheel return
to center and make sure the numerical value at center has remained
consistent. Press a button to move on. Your steering pot is now setup and
the unit cover can be replaced.

PEDAL POT REPLACEMENT
Place the pedal unit on a clean well-lit workbench with the pedal pads facing
away from you. Remove the bolts at Pivot D [Figure 10] and rotate the pedal
frame away from you towards the heel rest. To avoid scratching the finish put
some cushioning material between the pedal frame and the heel rest. The next
steps involve removing the pot cartridge and are illustrated step by step in Figure
14.
