Olderguy O2 clamp pressure switch adjust
From the instructions:
The pressure switch, if supplied, is set at its' minimum setting(approximately .5 psi) It has an adjustable range to 4 psi.
i am waiting on a AFPR and a Wallbro255 to dump the Vortech and stock FPR. It will take a couple more weeks. In the meantime, due to the IC effectiveness, the Vortech can only supply enough fuel to deliver 11.5 AFR's when I reach 3PSI.
That means while progressing between 0-1-2 psi, I go lean, say 13.5 or higher. This takes only a second in high RPMs, but if I pull from low RPMs its a longer lean tip in and I dont want to take any chances.
So, I took out the vacuum line connecting to the pressure switch and blew into it while idling at 14.7. it takes aprox 4/5 seconds to go from 14.7 to 11.0
What I am thinking is to set it to kick in earlier, just to be safe untill the AFPR arrives.
If I bring the screw outside the casing surface can I set to start working in atmosferic pressure, or 0.5 psi is really the minimum setting as the instructions say?
