Just a little tip I use that seems to help me. Starting with windows 7 control panel, I make sure my wheel is correctly calibrated as stated in the users ECCI handbook first. Open control panel/ devices and printers/click ECCI/ game controller settings/properties/settings/calibrate. Open the calibrate wizard, click next,find center point and push any button on controller. On the next screen that shows X-Y axis, I check the box where it says "show raw data'. When moving the wheel left and right max, it shows me 880 all the way right, and 440 when center and 0 all the way left. Then I know if my pots are set correctly on the wheel.Then I use the same number,880 as my steering wheel range in ASR controller options.
From there I like the following: 100% digital steering,throttle,and brake. ( don't have clutch)
75% speed sense
100% look ahead
0% head movement
I like the following in sensitivity:100% on steering axis...( which ever letters are mapped to these )
35% on brakes
100% on throttle
with 15% dead zone for my mapped brakes only.
The rest,0% dead zone
About the only time I don't use these settings is in fixed set servers. Then my steering and throttle may drop any where from 5% sensitivity, to 35% on the steering and possibly the throttle and brake may call for being lowered as well. It depends on the track, the set, and the controller used to make the set (keep the speed sense at 75%) Overall when building my own sets, I stick with my base controller settings, I start with 17 to 18 steer lock. This hardly ever changes, even when I run fixed sets. With fixed I adjust only the sensitivity. Keeping everything else the same , as much as possible.
Note: My ECCI is the 6000 HDI. If the raw data numbers in win7 calibration are not correct, then follow the instructions as to getting the pots adjusted correctly. Replacement may be needed if they are old and worn.
