The company I work for has been doing similar installs, 2-7 stop hydros, with the eci pixel. They've been using them for 3-4 years now and they seem to be pretty decent. Theyve even started using the pixel for traction mods. The company likes it cuz you can order the hydro mods as a package with the controller already mounted to the tank and wired to the pump and valve. Tech support takes a bit to get back to you but has been ok at solving the problem. The controllers them self are laid out pretty decent fairly simple to wire. I really like the security board for car/hall lockouts mounted right in the controller so no extra travelers. Ive done limited mods, maybe a dozen (3of them pixel), and the eci seems like a solid new era controller.
