Effect of 'Nominal Direct Injection Pressure'

[alackofspeed]

I'm would be grateful to anyone able to explain what the effect of the 'Nominal Direct Injection Pressure' setting is on an S-GDI. Many thanks.

Nominal injection pressure is a reference "pivot" pressure that the ECU uses as an input signal for closed-loop pressure control, referencing it against the actual pressure. It's generally a rounded median number. Changing it will result in a modification of the closed-loop control and is generally not required if you're targeting between the 50-150 bar range and hitting your targets.
