Thanks Mr. z. I did the axis transform in excel but did not increase the MAP estimation…Thx. MAF curve was same as 1 bar for me.

Sounds good. I’ll change the MAP estimation max and give it a shot. Sounds like I’m close. Thanks for all of your help. Need to now set up my scanner histo’s for the new 2 bar ranges
You're welcome.
Hey guys...frustrating weekend attempting to do the upgrade to the 2 bar.
Not sure what I am doing wrong or if I just have a bad sensor or adapter cable I installed the sensor and adapter cable, turned on the ignition to do the write and noticed a "reduced power" message on the dash that just stayed on.
Went ahead and did the write entire anyway and it seems to have installed fine but car would not start. Thought I might of bricked the ECU so I put the 1 bar back in and it started fine with the check engine light of course do to the incorrect linear and offset. But the ECU is OK.
Any idea what I am doing wrong...or if it could be the sensor or cable? It seems like the car immediately senses the MAP sensor is incorrect but I am not sure if this is supposed to go away once the new OS is updated. I will attach my tune again if someone would not mind looking at it to see if I have missed something critical in order for the update to work.
Any help would be greatly appreciated.

in pic 6 male plug that far right pin inside looks to be spread apart and maby not making proper contact with the male pin on other side plug ? , would be worth a check just encase as i think that pin is either reference voltage or signal voltage so will cause issues if not connected right
OK...I might have also opened the hole in my intake too much so there is no longer a good seal.
It must have a code in it when it shows reduced power..
Have you scanned it to find it for sure?

I will do that but I believe it’s a hardware issue. I blocked off the 2 bar port with a vacuum cap and it still throws the code yet when I reconnect the 1 bar it is fine. The car will not start with the 2 bar connected at all. I ordered a new 2 bar from Amazon and will return this one. Thanks for the help.
