OK, so I am starting to dial in all my parameters for my sensors on my EIS. I didn't really think about it too much before hand, but I bought an off the shelf fuel pressure sensor. How can I figure out the aux parameters to make the instrument read accurately? I know on the GRT MAP sensor etc. it tells you what to set it at. Do I need to buy a GRT branded fuel pressure sensor? Or is there a way to figure this out. Right now it is showing 10PSI with no pressure...
