Im doing a final project for a class where im building a electronic boost gauge using a stepper motor. Im using the stock map sensor off the fd as an input and was wondring if anyone has a spec sheet for it. It would save me alot of time and testing.

Thanks much, Mike

 

Page F-167 of the FSM

 

im looking around f-167 and although there is map information, thats not exactly what im looking for. Im trying to find a mapping of voltage vs pressure. I have it hooked up right now and im seeing about 9.0v at 1bar (open atmosphere) By squeezing the balloon i have hooked on it i can get up to about 10.16v.

Aside from it being fun, without another gauge on it to tell me the boost im wasting my time

 

The MAP sensor is linear. The FSM gives a starting point (range actually) and a couple of operational points to check.

If you really want to be precise, you'll need a MityVac and a voltmeter.
