neil brown Posted November 24, 2019 Report Share Posted November 24, 2019 As I have a spa digital gauge fitted monitoring fuel pressure have noticed a few times that at 1 bar of boost that fuel pressure only goes to 3.6 bar now and again and when letting off throttle fuel pressure drops to 1.6 bar the reg is 1:1 type but afr ratio is good at 11.3:1 do I have a fuel pump issue or reg issue or could it be the sensor for gauge playing up Quote Link to comment Share on other sites More sharing options...
Steve Posted November 25, 2019 Report Share Posted November 25, 2019 Look at pressure through the DIFFERENTIAL fuel pressure PID instead. Should stay close to your set fuelpressure at all times. Like 300kps (if thats what you set it to or run) Quote Link to comment Share on other sites More sharing options...

neil brown Posted December 25, 2019 Author Report Share Posted December 25, 2019 Turns out the fuel pressure sensor for the spa gauge is acting up as stated I had minus 0.5 bar of fuel pressure and afr ratio is fine Quote Link to comment Share on other sites More sharing options...
