I like the EPAS Performance kits, the variable assist and small parts are nice to complete the install, but I can't get over the $1.5k price tag. While the prices on the pulled EPAS units are going up a little due to hot-rodder demand, they're still only about $200. You can add the variable assist using an arduino, can-bus hat, and potentiometer or 4 position switch. I just bought another arduino and can-bus hat so I'll be working on decoding the messaging for the EPAS ECU shortly.
