2 bar map sensor
testing the interest in a 2 bar map sensor for the 05, but it will also work on the 97-04. The calibration of the sensor would not go negative like the current 2 bar GM sensor so you could use it in the LS1B and E40 ECU's. The retail price would be $69.95.

The GM 2 bar MAP sensor doesn't have a negative offset. The E40 TBSS I'm driving right now has one.
12580698 is $63.34 shipped from GM Parts Direct.

It's the 3 bar sensor that will plug in but won't work with the E40 as the table maxes out at 2.5 bar which is why I made one and DSteck makes/made them.

Why would they make the baro sensor go 2 bar? Not really asking the question because I know you didn't design it, but odd. Also if it is the baro sensor how do we know it does not have an offset. I don't see it's calibration in any software.

How do we know? God invented data sheets.

Listen to Steck on this one

The MAP sensor in the cobalt shows an offset but it does not give one for a baro sensor. I do not have any factory Cobalt files to go look and find the baro sensor offset.

I would prefer to be dead on. It used to be said to just blow the numbers up at 101KPA and all would be well, but we know that is not the case. Just trying to make a sensor that would be dead on. If there is one that exists that would even be better than me having to spend money to make one.

Dsteck,
Don't be smart about it. I am trying to find a solution and you are saying to just go with it. That is just like me telling you to go with the cheap 60# injectors and they work.
My question is where does the offset come from then and have you tested that MAP you are using to see how accurate it is? I don't remeber where I saw the offset on the Cobalt at but I think it was a -3 kpa, do we even need to worry about 3 kpa difference. If I can find a GM cal I will look and see what the cal is on the baro sensor.

Instead of insisting I'm wrong, do your research.
All the Delphi 2 bar sensors use the same internal core element with the same calibration curve. 200kPa linear value, 8kPa offset value.

Yes, I've tested it. I've tested it on the numerous cars I've tuned. I've tested it my personal TBSS which runs one. I've tested them on my own bench testing equipment that I have built (which is used for verifying my 2.5 and 3 bar sensors). I've done my homework. I'm not a shoot from the hip clown.
Why rely on trying to hunt down a calibration file when you can get the information needed STRAIGHT FROM THE MANUFACTURER'S DATA SHEET.
Sorry if I'm not cheery and bright when somebody repeatedly posts that I'm essentially talking out of my ***.
