Well i have one plumbed in for my fmic but just wondered what it does etc??

it measures the amount of air going to it which in turn allows the ecu to deliver the correct air:fuel ratio

this is my basic understanding of it.

You mean MAP I think. It's a pressure sensor, I believe the ecu uses it to measure boost pressures as it is between the turbo and the intake manifold. You also have a MAF sensor which is on the hose between the air filter and turbo that measures the air flow going into the turbo.

MAP sensor on pd130 (and other cars I believe) also measures the air intake temperature, and will retard the engine/fuelling if it is a bit hot.

Yeah map i ment!! Im guessn through your ecu port thibg you can measure boost pressures and intake temps, im running 1.9 bar

Anyone know what happens if the MAP sensor dies??? A jerky acceleration and plumes black smoke??? :wonder:

are you john holmes? :p

are you john holmes? :p

dont know who he is am from the 80's not the 50's :p

anyone know at what stage a 3 bar map sensor is required,

im running 1.9 bar and believe im still on the 2 bar map sensor

what are the differences?

When you run more than 2 Bar of Boost

You can of course still run more than 2 bar with a 2Bar sensor (Assuming the Turbo is capable) but the Ecu will not see it & be able to adjust the Fuel accordingly, Replacing with a 3 Bar unit removes the Ecu's white stick

ahh maybe ill just whack a 3 bar map sensor on it then
