Power fc says for stock intake car to drill holes and connect them between throotles and head! One map sensor on 3rd and one on 4th cyllinder.

So maybe you are wrong to connect them between intercooler and throotle body!

Bellow you can see my engine. If I connect the map sensors at the end of the intake at the point that I connect also fpr,avcr,boost gauge will be ok?

Or I must connect them exactly after the throotle body like if when we have 6throotle?

Or I must connect them at the 3rd and 4th cyllinder as power fc says?

I am very confused :P

I don't want to connect them wrong :D:)

yes pau is wrong. they must get their signal AFTER the throttle. you can stil do them the same as the PFC manual states (tap into the 3rd and 4th intake runner) or you can tap two holes and fit the nipples on the top of the plenum, or there may already be some points you can use on that plenum ( I can see some MAP take offs near the back of the plenum/surge tank).

the reason they must be after the throttle is they need to be reading both boost and vacuum. if you put it between the intercooler and before the throttle it wont get a proper vacuum reading when the throttle is shut.

Any explain why power fc has two map sensors?

As you tell me I can connect them everywhere in my plenum... and I will connect them as you tell me at the end of the plenum where I have connect map sensor from avc-r,fpr, sevro, boost gauge.

So as I connect both there they will have both exactly the same value.

So where is the point to have two map sensor the power fc?

the reason they have two maps sensors is they are desinged to work with the standard plenum/6 throttle set-up. so they can take 2 readings from 2 different runners. and average out the two, like they do with the standard Airflow meters. since you now have an aftermarket plenum and single throttle it's a different story. yes you could just use 1 MAP sensor, if you had an ECU that was designed to run one. but since you've bought the PFC that is designed to run with the 2 sensors just run with those two. try it from the vacuum ports at the back but just make sure you get decent readings from there (should do), otherwise just fit them as per normal, in runner 3 and 4.

It runs 2 map sensors because ITB cars vacuum per runner after throttle plate are never quite the same no matter how well ballanced they are, this way it takes an average between the two...

Fit both sensors off 2 nipples near the center of the manifold, if your using a greddy manifold put it where the the rest of the nipples are, remember to keep the map hoses as short as possible.

Put the IAT sensor behind the throttle towards runner one like you see the GTR's doing it, if you want pictures of how to do it email me.
