Tuning mafless oem operating system

[Dlong]

Can anyone help me locate a thread. I have seen a thread about running a 2bar map sensor without upgrading to a custom os. I can't seem to locate it again. I want to tune the car this way and then with a custom os for a little experiment and practice. I am new to tuning so I need the practice. I know it sounds crazy but I have unlimited dyno access. Thanks for your help.

Just read the Auto Tune tutorial and don't plug the MAF back in.

Thanks for the info. I'll try it.
