Vauxhall/GM 2 bar map sensor part number?
fha772 - 16/12/13 at 07:40 PM

Hi all,

I need a 2 bar map sensor, for my EFI conversion.
I seem to be struggling to find out a part number, or what model cars these will be found on.
Any help would be great.

Cheers Frank.

3 bar (for 2 bar of boost), part no- 16040749

Or if it's just for nasp +/- 1 bar, part no- 16137039

It's the 2 bar sensor I need, according to the guys at Canems, I'm starting out N/A, but then I'm planning to fit a low pressure turbo set up later, so a 2 bar is ideal, and saves swapping it later.

Does anyone know the part#, or what model car has a 2 bar MAP sensor?
I can't find a thing...

Anybody?
I'm completely stumped...

the std megasquirt internal one goes to 20 psi ?

an external 3 bar map sensor is what youll need to go to 30 psi (running 2 bar). this is an AC delco part number from america , ive got one , but i cant get to it right now .

which one do you actually need ? and what boost do you plan to run ? because it sounds like a std one will suffice...?

and youve already been given the part numbers

It's the 2 bar sensor I want, I'm using the Canems ecu, that doesn't have an internal map sensor.

I've been told the 2 bar sensor is what I need, I'm running the car N/A for now, and turbo'ing it later, but I'll only be running 6-10psi of boost max.
The 2 bar sensor will do both set ups.

cant find the 2 bar version, but we use the 3 bar. Over kill for your setup but will work fine

Will a 3 bar sensor be ok for running N/A?

BaileyPerformance - 25/12/13 at 04:30 PM

Yes, 3 bar will be fine, to be honest I have never seen a 2 bar GM, only 1 bar or 3 bar.

I think the confusion maybe the boost pressure rating, a 3 bar will go to 2 bar boost.

For example a standard Cosworth map sensor is known as 1 bar as it will read 1 bar boost.

You could use a standard Cosworth map sensor as you only plan to run less then 1 bar boost, these are cheap of eBay.
