Which 3-bar map?

[A.J.]

Is the caliber srt sensor a true 3-bar? I was thinking they were 2.5bar, as I had heard of the Neon SRT.

I applied 30 psi to the SRT Caliber 3 bar map sensor and watched the voltage on my scan tool. At 29-30 psi it's around 5 volts so I would say yes.

Oh ya, and this:

I guess that settles it!

I know where I'm getting my 3-bar!

Very interesting the Caliber unit works!!
The original GM 3bar map was used on the 1989 Turbo Trans Am for the boost gauge as they were MAF electronics.

Let me guess...
Is this one of the crappy ones or good ones?
Purchased from amazon I think.

Nope, Delphi is fine.

For the boost gauge?

[GLHS60]

Correct!!

Not surprised GM would do that. Even on my '98 Buick Regal GS it is a MAF car, but uses a MAP sensor only for the boost readout in the instrument cluster.

I guess it was lucky for us as it was the only readily available 3 bar MAP for the Super 60 package.

I realized when reading the specs on the Auberin's 3-bar sensor in a thread posted a few years back, they did the same thing (sensor range isn't full, in vacuum). decided against that one based on that single fact - I would think that might affect cruise and maybe idle readings and run it a bit rich, no big deal but probably not worth the few bucks it would save.

Get a freescale sensor and install it into a two bar case. Should be less than $20 after everything is done.

I made 2 3bar maps for $25

I have a Chinese 3 bar and if you map out the voltage it comes out to a 3.5 bar sensor.

I just picked up a caliber sensor from work, with my discount I got the sensor for 22 bucks. I think over the counter price was 26-27 bucks. The connector kit is more expensive than the sensor but I had one I cut off another harness.

Just to be sure, the 3 bar map sensor from the 89 trans am turbo will work? It will be at 0 volts at 0 psi? I found it on eBay for only $21. It has the common GM fitting. I will try to paste the link below.

I just ordered an 89 turbo trans am map sensor for ~$21 shipped on ebay. We will see how much of a piece of crap it is.

Thanks for being the guinea pig! I was going to get one myself but I don't need to get one for quite awhile. My car is still in pieces.

Nice work. It'll be hard for me to justify the soldering and finding spare cases given the cost of these C-srt units, but I may do some just because I'll be ordering some 4 bar units for a dual digital boost gauge I'm building.

[wheming]

Huh.
I've got an old one I believe, maybe I'll try this.
Do they have 3.5 bar and 4 bar also?
I might need more than just 3 bar scaling if the van build goes well.

I know for sure that freescale makes a 4 bar map. I know there are 3.5 bar maps out there, but I'm not positive that freescale makes one.
