I should make a disclaimer in my signature, even though I am a licensed technician and have the skills to keep your turbine engine from killing you, I am just getting my feet wet on modern EFI marine systems and am just relaying you what I think I've learned over the last few months.
That's what I meant when I wrote about not using digital gauges- if it's less expensive/hassle to re-do the digital ones, it may be easier to go with analog. The problem with the digital gauge system is that they're very sensitive to bad grounding. Hoping and praying they'll work is the hassle I'm referring to.
