You mean the plate's clearance against the intake inlet or the metered air after the ICV?
I just came back from testing and I am only getting 4 Bar by connecting the outlet to the cold start valve on the fuel distributor to the CIS fuel pressure measuring gauge. This time I only used a single hose so I don't get confused with the two hoses setup. I then unhooked the hose and measured at the test outlet (lower chamber) and pretty much got the same result. If my gauge is measuring correctly (which in my case I ALWAYS doubt) this means that the EHA is NOT compensating to create a 0.4 Bar difference between the upper and lower chambers. I guess when it cools dwn a bit outside I will go back and turn the EHA inner allen adjustment screw clockwise to get a differential reading/setup, right?
Could it also be that because the pressure is so low that the EHA doesn't even bother to work the pressure?
