MAP sensor for non turbo application

Post by andytat »

Hi Guys.

Must the MAP sensor be connected to intake vacuum on a non turbo engine?
Or, is it open to atmosphere to enable the ECU to detect barometric pressure?

Cheers.

You can do either.
If it's on throttle bodies, most people don't bother.

Thanks Alex.

It's on throttle bodies.
So, I don't need a MAP sensor at all then?

Cheers.

Not unless you plan on driving up Everest. I have one connected barametric just for curiosity, it hardly changes fueling ever.

MAP....Manifold Absolute Pressure.

MAP and Baro are two different applications.

As Rob says, no point in this country.

The vacuum fuelling will just be backed in to the map.
