I'm doing a turbo build on a monte carlo with the stock ECM, and I wanted to know how to change from the stock one bar to a two bar MAP sensor in HP tuners. I know I need to be in the OS tab in the editor, but I've opened that up and nothings there for me. To be specific, I have a P04 ECM. Do I have to get a file, or a whole ECM from a supercharged monte, and transfer my existing tuning changes to it?
