The $58 code (it's really the same code, I4 or V6) has a few cool things built in. For example, if knock doesn't stop when timing is retarded, the ecm is programmed to add fuel then to reduce boost. And the ecm will control the boost control valve. I don't know of a MAF ecm for four cylinder that will do that.
The values to change are max advance, max retard, and reference angle. It's simple but not... Many definition files out there have the wrong conversions. And you want to know whether or not you're using a crank with the notches 10 degrees advanced, which would change the reference angle from 60 deg to 70 deg. If you have the correct stock calibration for your car I could likely pull the limits out of the file.
