From your Hydra manual: “Injector phasing: This map controls injection timing or when the injectors fire with reference to TDC position. 180 degrees in the map signifies the firing of the injector right at TDC of intake valve opening. Degrees represented in crankshaft rotation."
If this doesn’t make sense then you shouldn’t be anywhere near this map trying to tune it.
Leave it alone as it’s fine as is.
