As I was looking at the schematics v3.3, I could help noticing that pre_inj0x signals are all parallel connected to OC0 output signall (as PWM mask).
So, If I use LOW-Z injectors and PWM, then all the INJ0X outputs will PWM at the same frequency... So what if I use only INJ00-INJ03 for Low-Z and INJ05-INJ06 for let's say IAC and Boost valve... So PWM would make me problems with IAC and boost solenoid....
How does this PWM low-Z thinngy works? Is this PWM constant, so injectors would get less current? How do we calculate this PWM for lets say 2ohm injectors?
