Let's remember that the Andial unit works in the exact same manner as an adjustable WUR except that it is controlled by an electrical signal rather than boost/manifold pressure.

Andial used a pulsing injector to limit the fuel flow returning to the tank (post WUR), thereby increasing the pressure in the CIS fuel delivery system, and the amount of fuel being delivered. It obviously has limitations, just as the WUR does, and I'm not sure how effective/usuable the programming was in the Andial unit, but in theory it should do no better or worse than the adjustable WUR.

I have an Andial unit sitting in my toolbox - I never got around to putting it on my car because I have good A/F ratios with my current setup. I would have no aversion to using it in place of having my WUR modified.
