So after my short dyno session I found I'm having a fuel pressure problem at wot. Only 29lbs at the rail sensor. So I brought car home did pprv delete and checked pump clearance going into top of the basket....and was told log the pressure see what I get before another 2 hour ride to the dyno. So I downloaded live link got everything hooked up get all my options from the table....select fuel pressure drop and duty cycle from fuel pump section. When I hit ok it loads the chart but with car running its like I'm getting no signals....I've never done this before....am I missing a step? My programmer says passing through to live link...I'm stumped....help please.
