I wouldn't worry too much yet how the wheel is reacting in Daytona. The first step should be getting the wheel to a good general starting point for all games using the amc and then you can adjust on a per game basis easy enough in software. As much as the Windows game controller sucks for setting up the amc at least you can use the effects tests to compare to my wheel and in comparison yours still seems a bit weak with no centering.
Have you taken off the pot yet? That should be step one then turning up the reference input on the amc.
As a side note double check the voltage leaving the Logitech motor outputs. One other thing you can try is turning up the current limit potentiometer on the amc

I adjusted the pot and at full lock left and right I get 23.5. The volts coming from the logitech motor output is .3. I couldnt get it any closer without over or under. believe it or not but ref and current are maxed out to get it to move like it does now.
brad808:
Just another thought but what is the amp rating on the 12v power supply going to the Logitech (it is actually reading 12v with a volt meter right)?
Something isn't getting enough juice from somewhere. Just as a temporary test maybe try hooking up the original power supply to the Logitech wheel and see if you can get strong force from the wheel. Don't leave it hooked up but it may start eliminating pieces of the puzzle

Hi all,
Thought I'd add to this thread as its a question I have too for my driving cab.
Picked up a Cruisin World which uses a Happ steering wheel and inside it there's a Rae 3120301 motor. Specs on the body show 90 Volts DC, 1.51 amps.
Has anyone hacked one of these using an AMC 30A8T and 24V power supply? I was going to use something like this: http://www.ebay.com.au/itm/110920245043 , but this is probably going to be overkill, considering the motor is only rated to 1.51A? Is the FF going to be strong using this motor?
