As above, it's your car you do what you want with it.
The Turbo will also run on cheap $20 4 lire oil packs, 91 Octane fuel and a rubbish Pod filter or even no filter at all, as well as just pulling the vac hose from the turbo pressure sensor to get the fuel cut.
it's your choice.

Re: Gen 6 FCD + Extra's for the SW20 Turbo
It was a serious question. I actually want to know what else it does. Obviously you've done a lot of research into this to build a product that replicates the nature of the MAP sensor's output voltage so there must be a really good reason why you did that and I'm genuinely interested in knowing that reason.
If the MAP sensor does in fact serve an important purpose other than controlling a useless boost gauge and determining the fuel cut off point (that we're trying to get rid of) I think that would be good info to have for people that just go ahead and disable the MAP sensor.

Re: Gen 6 FCD + Extra's for the SW20 Turbo
A quick bit of research throws up both HKS and Greddy making FCD's.
So really to me there was never the question of whether I should use one or not, only to build a better one with a few extra functions specific to the MR2 that had showed up as areas of obvious weakness during road testing.It was perhaps a bit unfortunate I didn't road test the requirement for the fpr switch, but then again its just opening a circuit at 10psi thats already open at 1-2psi so no harm done and its no longer required as part of the FCD function.
I found the following artical quite interesting reading. Read the second paragraph if nothing else.

Maybe it's just me that's giving some credit to the likes of HKS and Greddy that a FCD makes sense. One would generally come to the conclusion that they already did the required research.
Bottom line is that in fitting one you can be 100% certain your not stuffing up any other parameters in the engine that could be derived from this signal so the decision to fit one was easy.
