I was wondering if anyone had the voltage readings for the JDM map sensor. I.E. 1 volt = 14 psi etc etc. Reason I ask is Im trying to get a digital gauge made up to display boost directly from the map sensor to help clean up the clutter under the hood. I was speaking with the guys at Dynotune today and was told if I had the voltages they would most likely be able to make a gauge for me. Any help would be great.

 

You can find some assumption based "answers" here:

It would probably be better to just test it though. How are you going to tap the signal without interfering with what is sent to the ECU?

 

would it really be all that bad to just tap the stock wire at the ecu ? I wonder how it would make performance suffer?
