hi bob, when a fuel injected 81-83 is converted to carb you lose the mpg,& fuel range to empty display readouts. this is because there is no longer the fuel injection computer to measure all this.(basically- i know theres more to it than that but i don't think its interesting enough to go into any more detail!) you do retain the readout for amount of fuel in the tank. one of my 78 nybs had an aftermarket computer added that did give instant/average mpg. i'd love to know if something like that could be added to an 81-83 imp so it would give back the mpg readout. any body know of such a thing? mark victoria & vancouver bc canada 81 imp 78 salon __________________________________________________ Do You Yahoo!?
