Default Electronic vs. Mechanical gauges

hey guys, i was wondering what is the difference and which is easier to install? i have been told both, that the electronic ones are easier and that the mechanical ones are easier, what have you guys installed and which do you prefer? i figured the electronic ones must be easier because they cost at least twice as much, can someone explain why that is as well? thanks for the help.

as far as ease of use and installation, nothing beats electronics, mechanicals are more accurate usually, but it depends on the guage and the manufacturer.

An example would be an oil pressure gauge. The electronic version would be a sender installed in your engine block or maybe at the oil filter which reads the pressure, then sends a signal to the gauge via a wire. A mechanical oil pressure gauge would actually have to route some oil into the cabin to the gauge so it can measure the pressure directly.

If electronic gauges are less accurate, then it's not by so much that I would notice, and I personally am not hardcore enough to want oil and/or fuel entering my cabin just so a gauge can take measurements. So I went the electronic route.

FWIW, I have my Omori mechanical boost gauge and SBC ID both tapped at the same place, and the Omori consistantly reads 0.5 to 1 psi lower than the SBC ID.

The only mechanical gauge i would get would be boost, everything else should be electrical just for safety sake and for a cleaner install.

just to add to this, i had my SBC-ID, then switched between my GReddy peak/hold boost gauge and Defi boost/timer unit. the GReddy was dead on with the SBC-ID, the Defi read about 0.7bar higher than the SBC-ID.
