I tried looking for something that could tell me my instant fuel economy and my overall fuel economy, but I had no luck. Its like one of those Driver Information Centers in some of the GM cars that shows all of that information, the Cobalts have it. Does anyone know if an aftermarket product like this exists? if not then can one from older GM car be installed to work in a 2001 2.4L cavy? If you take a look at the pin outs at one of these they got all the same sensors as in the cavalier, but i'm thinking that its calibrated for a certain car so it won't work.

Do you mean something like this?




This is an aftermarket Fuel Economy gauge.
