Default 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

Check the part number. If it's 22012AA090 then its the 3 bar map sensor. Not sure on fitment without mapping changes though.

Cheers Daz.

Does anyone know if a remap is required if there's a difference in the map sensor voltage, or does the Scott T chip cover this?

Yes remap is required as calibration is different .
