So. Talk to me about this new "SOI offset".

If it's the one near the top that says "global offset", then that parameter takes whatever calculation for SOI that is made and automatically adds or subtracts that value across the board.

Say with all of the calculated SOI maps you would end up with 26.5 degrees of SOI BTDC at a certain operating condition. If you put a "-5" in the global offset parameter, then the PCM will tell the IDM to fire an injector at 21.5 degrees. Same if you put in a "2"; you'd end up with 28.5 degrees.
