As far as I know ACR has no precision in their tone curves. They just use a gamma correction to an intermedate color space for the initial conversion, and then convert from that space to the output space, where you can apply a tone curve and the goofy sliders. It's **** software. I'm not recommending color perfect, but they have an add on of some kind to get a linear file out of an epson scanner, I forget what it's called. This seems really convoluted to me though, just raise the value in the middle box in levels in epson scan and output a 16 bit tiff. Epson is a serious imaging company, not a shill network like adobe.
