I was looking into modifying the pedals with a loadcell. (something like this dude: https://chippedwood.wordpress.com/2015/07/07/46/) And looked at http://www.leobodnar.com/shop/index.php?main_page=product_info&products_id=199 for a loadcell amplifier to connect to a arduino. but have you found other solutions with the cable you mentioned?
No the simplest solution is what you found. The G27 being analogical need just a load cell and an amplifier circuit, and it simply work. The cable is supposed to pass the signal from 256 to 1024 bits ... it probably work , can't test it.
Yes I know that. I nearly bought one until I found with my DD setup you don't need it. The circuit board provided can deal with it. You connect it direct to the circuit board. You just can't use a USB.
