Using iRacing wheel settings wizard with my base v2 I got a range of 0 to 65535 values for axis which is a 16 bit value so I thought it had been improved.... 
compared for example of 1024 values of T500rs or 255 values of G25 or 4096 (12bit) value of Bodnard controller.
For me, the most important is the time of response of the controller and the number of values between min to max more values you have more you control finely your axe/pedal...
It appears that those total values do not give the true resolution of the pedals. When I cited those values to David Tucker of iRacing he responded as follows: "The utility is reporting a range from 0 to 65535, or 16 bits of resolution, however I'm positive that these pedals do not in fact have 16 bits of resolution." He then provided me with a utility to measure the resolution and it came out to 8 bits. I certainly don't really understand any of this. I'm just reporting the results I got using the utility that was provided.
Below are excerpts of my private messages with David.

Thanks, David. I got 256, which would be 8 bits of resolution. This is less than the 10 bits if I connected the pedals via usb.
Thanks again.

Ok, I posted a hacked version of joyInfo here (called joyinfo_delta.exe). I modified it so that instead of reporting the devices position, I report the change in position for the center value (between min and max). Try to push on your pedals really slowly and see if you get a stable number there.
On my XBox360 controllers trigger I got +/-128, with a max reading of 65535 so dividing 65535 by 128 gives me a value of 512 or 9 bits of resolution. Interestingly on the joystick I get +/-309 or about 212 samples (probably 256 samples with a bit of processing in the joystick itself).

I'm afraid you can't work out the resolution from that utility, at least I don't know of a way. The utility is reporting a range from 0 to 65535, or 16 bits of resolution, however I'm positive that these pedals do not in fact have 16 bits of resolution.
The only way I know of to work out the resolution is to record the output from your pedal while slowly pressing down on the brake and then calculating the delta, or change from sample to sample, to see if the readings tend to jump by a fixed amount (say steps of 32). To make things worse there are several different units that DirectInput can give you, and that will tend to add noise to the reported values making it harder to detect the resolution. And on top of that most utilities report the calibrated range and that further muddles up the data.
. . . .
You may be able to get a bit more information out of my 'JoyInfo' utility. This utility will report the raw values from the pedals without trying to upscale it to the 65535 range and it will remove any calibration information so you can tell if the pedals are using the full range of travel or not. If you are careful while pressing the pedal you may even be able to see the jumps in the output, but it is better to use a computer program to log the information over a wider range of motion.
To use it just press each pedal all the way down in turn and then hit the export button. There is a bit of information printed on the dialog, but the majority of it ends up in a file written to your documents folder.
