Does anyone know what the injector duty cycle is for the DI injector used in the 4.0L platform?
This injector (MB PN 256-070-56-00-80) is used on multiple engines including the AMG GT where my interest lies.
The GT comes with multiple levels of performance output using this same injector:
The GT is about 469hp
The GTS about 503
The GTR about 577
So, I imagine fueling varies and that would mean different duty cycles for the same injector. For the most part, the differences BT the GT(469hp) and GTS(503hp) appears to be only a 0.2 Bar increase in boost.
If anyone knows the duty cycle at any level across these variants, or all 3, would appreciate it.
