Does anyone have the scaling values and data required to run a LSJ 2BAR MAP sensor in a E67 ECU?

This is an over the top performance Harrop Blower kit for a 2008 2.4L Cobalt Sport. Any help with this would be appreciated. It has a ton of stuff changed like IAT1 sensor, TB, etc and had custom harnesses made to adapt everything.

It was tuned with Trifecta tuning before anything else was available and the OS has been changed

I found out this is not a changed OS

Just enter in something around 188 - 200 in B2101 and key on engine off, check kPa reads 100, I assume you are at sea level in Miami :sly:
If it's not right then just keep altering B2101.

Although this would work, I am sure pulling the LSJ values from a stock calibration would be accurate.

The proper values for those looking are:
MAP Scalar: 270.59
MAP Offset: -3.30

Thanks Paul. -3.30 is odd, but if that's what GM have then we'll have to accept it.

I verified these values this morning when I got to the shop. They work perfect.

This car now has a SIP sensor and I am trying to figure out what it is wired into to make it work, what it is calculating, etc
