Map sensor query

Map sensor query
MY94 WRX; TD05, front mount, full de-cat.
Also fitted with an early ScottT scoobyecu chip running 16psi with a 17.5 fuel cut.
However on track days when temperatures get higher, the boost creeps up triggering the fuel cut.
A recent service showed a stored fault code in the memory for the MAP sensor (early type sensor - 1.2 bar)
So a couple of questions for the experts.
Can I fit a MAP sensor (1.7 bar) from a later 98 model ( I have one in my garage) without any problems with voltage signals?
I read a recent thread that a remap is needed, but I don't have the later ESL board. Is that correct?
Or should I just fit a FCD (HKS or Hybrid from Harvey)?
Or indeed any other suggestions?
I do plan on a replacement ecu in the future, but recent cash has been spent on brakes and handling, so not yet.
Many thanks
Dave
