There's a few things to overcome with the Stageas, Liz:
We're trying to use R34 PFC's on s2 R33 engines, Liz, which is where one of the issues is.
The s1 Stagea ECU, even though it *probably and most likely* runs an R33 program, has an R34 plug, which is problem two.
There seems to be a few different parameters run on different pins between R33 and R34.
The Stageas have AWD, and in that regard they're the only RB25-engined Nissans to use a turbo motor and AWD together (whether it's the R33 or R34 Neo).
Even the s2 Stagea, with the R34's Neo motor, needs mods to the PFC wiring to sort out issues with traction control and the engine light staying on.
That list is the stuff that I'm aware of so far, so who knows what else will pop up.
It HAS been done (I think Millenium Motorsport in Qld were amongst the first in Australia, but they were and maybe still are unwilling to share the information), so there's no reason why Duncan and I won't eventually be able to have s1 Stageas with the R34 PFC - it's just a matter of time and having all the correct information together to make it all happen.
Back on topic, I'm still keen for a run on the dyno, even with the standard ECU still in my car.
