Digital instrument panel
I have read numerous very interesting threads about various digital instrument panel/digital dashboard/virtual instrumentation projects and have several questions on the subject.
Let me start with describing what I want to do and a little about myself.
I have been in the computer industry for close to 35 years and I've been building custom cars even longer (yeah, I'm an old goat with gray hair ). I've written C code since, well, since C has existed. I've written Unix (and variations like Linux) system interfaces since, yeah, since Unix came into existance (told ya I was old).
I am building a 1934 Ford pickup street rod and would like to replace the usual array of analog gauges (speedometer, odometer, tachometer, engine temp, oil pressure, fuel level, battery voltage) with computerized representations of the gauges along with controlling heat and A/C.
I also want the usual features in a car computer such as music, video, GPS, etc.
It has a carbureted Chevy 350 with no OBD (I, II or otherwise) so getting input there is not an option. How does one go about getting input from the various sending units such as water temp, oil pressure and fuel level (level, not pressure) into a computer?
I have a pulse generator for an electronic speedometer so that is one sending unit sort of out of the way.
Has anyone out there completed such a project and, if so, would you be willing to share info on how to achieve it?
the fusion brain has 10 analog sensor inputs. you may be able to hook your sending units up to it.
there is an MP3car sub-forum dedicated to the fusion brain. check it out here
I have read a ton of threads in the FB fourm now and it indeed looks like it will accomplish what I want to do--now to figure out exactly how to go about it.
I have a few questions about FB and will post them in that forum.
Thanks for the help.
If your interested in changing from a carb to fuel injected, you could get a standalone engine management system, several comes mind but if your looking for something on the cheap I would go with Megasquirt (msefi.com) its open source, you can output all engine parameters to a dedicated display or to your in car computer. Since your a veteran to computers and mechanics I believe you will find it a breeze, the hardest part of the megasquirt(IMO) is learning how to tune the engne. let us know how it goes and good luck!
