Hi there! WITHOUT going way OT like in that injection discussion, I would like to know if someone has used some kind of sensor to measure fuel flow. The idea is to measure the instantaneous fuel consuption. Problem is that it's a small flow. If cars spent more fuel, it would be a lot easier! 8) Why am I here? Well, I want to build a small car-computer, based on PIC. I really would like to include fuel consuption indication on its features. Thanx, Nuno Pedrosa. -- _/^\_ __ _____/\_________________________________oOOo__O-O__oOOo______/oo\____ /\/ / Nuno Filipe Freitas Pedrosa __ /..\__/ \ \/\ mailto:Nuno.Pedrosa@oen.siemens.de /`'\\__/-\ __ \/\ \ Tel. : 0049-89-72222342 \__/ \__//@@\ ___/ /\/_______________________________________________/OO\_..__\__/_ \/ \__/
