Greddy Inteligent Infometer?

[GTR 94]

i am curently looking at purchasing one of these for my R32 GTR but am just wondering if anyone else is running one, or knows of some one who is?? my main concern is, it points out that it will run from the diagnosis point in the car on a standard ECU, will this mean that an aftermarket ECU will not be applicable, or are they just pointing out that it will still work on a standard one??

here is the site i found it
