haltech map sensor
Anyone know if the haltech map sensors found on speedmachine would work with a stock ecu if the wiring was made compatable? cause i cant seem to find a N370 part number pressure sensor anywhere...

Yes.
The stock Turbo II boost sensors are 2-bar MAP sensors.
Just keep in mind that the wiring between S4 and S5 boost sensors are different.
One uses +12VDC and +5VDC, while the other uses just +5VDC (I think).
The GM sensor that Haltech uses just requires the +5VDC, ground, and signal.

Its been said that the stock map sensor found on FC's is similar to a haltech 2bar (GM styled), but its very likely that the output characteristics aren't presicely the same, if you do use it with a stock ECU you might need a AFC of some kind to dial it right.
Otherwise, just toss the stock ECU in a box put it away and use a haltech.
But Ted is right, the stock map sensors use both 5v and 12v, so you need to confirm with a wiring diagram to see how to connect it, and make sure you dont feed 12v to the GM sensor or you'll probably kill it.
