Electronic vs Mech Guages
 

hey fellas....
can someone gimme the scoop on the pros and cons of electronic vs mech guages?

Electric Gauges:
Pros - Usually come with neat features like peak hold, memory, and other stuff
Cons - A little more expensive, a little harder to install

Mechanical Gauges:
Pros - Cheap
Cons - Cheap

I do NOT recommend mechanical gauges for measuring fluid pressure because that requires routing the fluid into the cockpit area. If there is a failure you could have a very big problem (like fuel in your cockpit, etc). Some gauges use isolators, but I still don't like the idea of an isolator running into the dash either. Most people use a mechanical boost gauge because that is just air and its simple and harmless, but electrical for things like water/oil temp and fuel/oil pressure. Of course all voltmeter's, A/F meters, and EGT meters are electrical.

so i gather that there is no difference in accuracy between the two (or it's negligible)?

someone told me that an EGT guage would be a better way to determine if you are running rich/lean (better than a/f)
can someone educate me on this subject?

thanks for the info guys

you can get the DIY wideband from OZ for like $400
