Electroniv vs. Mechanic Boost gage...whats the difference?

[JoeyJigglesGSX]

just as the title says...what is the difference between an electronic boost gauge and a mechanical?

Mechanical boost controllers are inexpensive, simple to install, simple to use, but you have to pop the hood every time you want to adjust your boost settings.

Electronic boost controllers are expensive, somewhat complex to use (a bi*** for daily driving if you have one that uses fuzzy logic). don't need to pop the hood to adjust.

Unless you're always in a constant state of tune with your car save your money and go with a reliable manual boost controller, with most daily driven cars, boost is a "set it and forget it" kind of thing

hes asking about gauges... not controllers.

Electrical gauges use a sending unit or transmitter which sends a resistance or current/voltage signal to the gauge. In mechanical gauges the air goes directly into the gauge where a bourdon tube expands with pressure causing calibrated linkage to move the pointer accordingly. A mechanical gauge will always be more accurate than a sender type (resistance) electrical gauge but some current or voltage based gauges can be fairly accurate if the transducer is of high quality.

Damnit, I'm a fool.....

Electronic gauges don't require you to run that crappy, easy to kink nylon line through the firewall for one. Instead it monitors boost through a MAP sensor.

its cool...thanks for the responses anyway...damn i wish i did the research before, i bought an Autometer C2 boost gauge, i had no choice of it being electronic or not...i hate anything dealing with wires, makes everything soo complicated...the only reason why i asked was because my battery died on me the other day and when i get everything running agian my gauge was reading 10 psi of vac...i was so pissed off, but then i turned my car off and later on turned it back on and everything is fine..

do you guys think that electronic guages are innacurate?

do you guys think that electronic guages are innacurate?

Yes they can be. Alot of the automotive transducers are cheap and inacurate compared to an industrial 4-20 mA or 1-5 vdc output transmitter but it is a cost thing. Do you want to pay $400 or more for a transmitter that is accurate to +/- 1% scale? Most people can live with the 10% or so of a $50 unit.
