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 ***.
Dsteck,
I wasn't saying you were wrong, I was asking for verification or if you had bench tested it to verify their data sheet was correct. I am not a shoot from the hip guy also and I am not going to have something made that doesn't work. If GM already has one, that is the best situation for me. I had not seen one that worked yet, but honestly I have also not hunted for one. I talked to Greg B. a while back and I was going to just run the old style unit, but figured I would provide a better solution. Look I have also seen you question Greg B, and he is not a shoot from the hip kind of guy either, but everyone needs to be questioned and make sure the data is right. I answered my own questions about the offset by asking about your data in this thread. I have not seen the manufactures data sheet on the sensors, that is why I was asking about yours. No disrespect was meant towards you.

Dsteck,
My other question was looking at the data you gave for 200 and 8, the cal in HP Tuners does not show that. That is where the real question comes in. If I get one here and put it on the bench I will probably answer this, but I would like to hear what you have to say about. Are you putting 200 and 8 in the offset and it works?

I have used the sensor in quite a few LS2 cars and it is accurate.

Why would it show that specific data? Maybe investigate what 2 bar MAP data HP actually populates when generically converting to a 2 bar OS.

That is in the cal, if you go into diagnostic airflow you will see the MAP setup. You can't just plug in a 2 bar or 3 bar sensor.

Um...I guess you will never get it no matter how its presented to you.

Best of luck

Road Rebel,
That problem is I do get it. You can't just plug a 2 bar map sensor in or a 3 bar for that matter.
In the calibration there is a table for setting the specifics of the MAP, that is the table I am asking about. On a E40 and a LS1 B they do not allow a negative offset. If you look at the factory calibration for the Cobalt that the sensor in question came from, it show a -3 kpa offset in that table. MY QUESTION is does it matter that we only have a 3 kpa difference or does this MAP sensor (baro sensor) have a different setting.
What is more plain than that, pretty straight forward question, however I have been told to use this sensor and it just works, but not data. So what exactly is that I am not getting than?

Also you can't convert to a 2 bar OS unless you want to run speed density, I want to run the MAF, however I want the MAP to be accurate in the upper areas as a back up.

Oh my god. The part number I posted IS NOT THE SAME ONE YOU ARE THINKING OF! The one you're talking about with a negative offset is a 2.5 bar TMAP.



You don't have to run speed density in a 2 bar OS with the E40. You very much can still use the MAF. I do it plenty.

Dsteck,

I understand that. That is what I had asked you earlier and you never responded. The sensor you are using, I understand that we do not know what setting is being used in HP because we can't see it. Are you just using 200kpa and 0 in the offset and it all works well? It is a shame we have to go through all this to get to that. I was going to have a sensor made that would allow that setting and be correct. If there is already something out there that is even better, but you never answered that specific question, of course than others came in wondering if I get it. Of course I do, I am asking some pretty educated questions here that most don't understand. It would be nice to work together instead of bumping heads right.

Post 20 is clear as day. 200kpa linear, 8kPa offset. Not 0. I don't know where you're getting that zero from. I'm telling you that something already exists, others confirm it, and you still don't seem to care. I don't know where the miscommunication is. There's a data sheet from the manufacturer of the sensor that allows you to calculate the linear and offset values for yourself.

Look up a STS-V tune file.

I didn't see that, sorry.

I ordered the sensor last week, the part number you listed. Do you know what the manufacturer's part number is? The GM book is not listing any vendor for it. I am going to compare it to the one that was going to be made and see if they were just trying to pull one on me. However it was priced way cheaper than what the dealer is selling to me for.
