Les, Depends on the age of your vehicle. If it's newer - the guys who are saying digital lag are right. Why doesn't your computer boot faster after an upgrade? Same problem. A digital gauge will go rail to rail - that is, 0 to 5 volts for CMOS stuff. Heaven forbid you should pay more for faster processors that would do analog to digital conversions faster. As it is, you buy slow stuff than only sample the input from the analog to digital conversion of the gas tank at slow rates - because gas is burned at a fairly slow rate. Reset the thing -- turn it off, then on -- and you get a new boot, a new start on your sampling. They expect you'll know you've just put gas in and won't want to pay for a gauge that tells you what you already know. If you have an old gauge -- pre 80's or so -- the gauge is a volt meter. The float in the tank gives more or less voltage depending on resistance in the varistat (like a light dimmer) in the sensor. Problem is, those thing bounce up and down like crazy - so gauges for them are packed in grease to get a fairly sensible reading. My guess is that you have a digital system, so you need to reboot your computer to get a true reading. If that's no good - then you have to pay more for a faster analog to digital conversion to tell you what the best computer - your brain - already knows -- that you've refilled the tank. Steve
