Heres the tables against one another.....the corrections are in completely different spots....and these will change depending on what injector you're running....and how low your pw is getting and how linear the pw is. It is not just completely normal functionality of the ecu. the ecu is simply doing what its told. take one table and paste it into the other and see how normal your car functions...
Then take the per cylinder fueling comps from a tf car and put em in a sf car.....then take the per cyl timing comps......
The roms are vastly different. If you try to tune the same mods on a 16bit car vs a sf car vs a tf car, the cars will drive very differntly with the stock tables in there. the 16bit cars have simple 2d per cyl fueling/timing tables, the newer 32 bits are 3d, and the tf vs sf cars are adding/subtracting fuel at very diff rpm and pw.
When you combine all these differences you can get fueling results that are 20-40% off.
