To my understanding, adjusting the EHA properly requires checking the difference in fuel pressures between upper and lower chambers and that difference is 0.4 bar?

also, at idle the EHA should be pulling 0 mA of current?

what do I do to set up the test to check the fuel pressures? what tools do I need and how do I set this up?

what harness are people getting to test the EHA valve currents?

my current method of setting the mixtures with lambda tower and EHA are just manual calibration based on reading duty cycle and I've narrowed it to around 45% at idle and 50% at 2500RPM no load. the car runs better than before, but I want to make sure I have the EHA perfect.
