Its is possible to modify an R34GTR MFD to output to a standard screen, but for most ppl it is to much time, effort & $$$.
Personally I'd be happy with software for PC that could be skinned to act/look the same as the 34 MFD, possibly using ECUtalk or similar as a service if need be... unfortunately nothing half decent is out there(that i've found) so ill end up having to sort it out for myself lol
btw. HKS Camp 2 has been released, but still very $$$...
