there's a new one that supplements the original when
you go to the custom OSes.
You may have to play some with injector offset value,
it's certain to be somewhat different than the stockers
but good luck finding any data; cut and try. You may
also need to shorten the minimum allowed pulse width,
see if you are bumping up against that and being forced
to overfuel as a result.

Are you 100% sure you have a 2-bar map sensor in the car?
What was the part number on it?
This is because a stock sensor will report the full 5 volts at key-on. Which now with your 2-bar OS, 5 volts means 15 psi of boost. The stock sensor uses 0-5 volts to represent full vacuum (0v) to full atmosheric pressure (5v).
The correct sensor for your OS will report 2.5v (or so) at key-on. Which your 2-bar OS now recognizes as regular atmospheric pressure. A working 2-bar sensor uses 0-5 volts to represent full vacuum to 15 lbs of boost, with normal atmospheric pressure in the middle of the range.
