I called my local dealership and they can't find anything for the stock truck manifold that has increased capability. Anyone have a part number for a 2 bar or a 3 bar map sensor from GM that fits in the stock location? I have a GN 2bar sensor, but was hoping for a plug and play solution. If there isn't a stock 3bar sensor, does anyone have a part number for a 3bar sensor that can be adapted (like the GN sensor)?

I want both sensors -- I will be able to write 100% supported 2bar tunes and should be able to write 3bar tunes in some betaware.

1 million thanks in advance!

2 BAR

Connector keying might be different though.

It's the BARO sensor on the supercharged saturn ION

K now heres a rumour ive heard from the j-body board and one of our customers with a built boosted J at our shop, he was tellin me the Aztec has a 3 bar MAP, he has no idea why but apparently it does? any truth to this? further more wouldnt teh GTP have a 2 or 3 bar map?

You know that presents an interesting question. If they are using the 2 bar MAP on those cars, how are they handling the flow throught the MAF and how do they deal with it in the PCM on those cars.

probably the same way the 3800 has been doing it for years

There's nothing to explain. They are boosted from the factory.

Think about the power levels involved.

We don't run into problems until you run out of MAF range, usually over 600HP.

Not too many factory cars doing that

Anyone have pics of these sensors? Cause I know the GTP one won't work with my Mag. M/C or at least be used in the same place.

Aside from the wire connector, would the cobalt or ion sensor be a direct fit replacement for 1 bar lsx series map sensor?

Ive got two part numbers in our inventory here that are both 3 bar MAPs, just different plugs. 12085502 and 12223861. I couldn't tell you which will work with your truck.

Hello Fellow Gear Heads,

I am trying to find out if I have a 1 or 2 bar map sensor. If it is a 1 bar, what do you recommend and where can I get the sensor and plug as well? Thank you all in advance.
