I have been looking into raspberry but haven't found anyone doing exactly what I want.
I have an 86 F250 powertrain and a 76 f250 body. The problem is the electronics on the 86 are slightly more advanced than the 76 electronics. I could easily remedy this with a couple relays circuits etc. I however think it would be really cool to have electronic display.
The couple of problems I am having now and how I plan to solve them are as follows;
The speedometer set up for the two vehicles are completely different. I want to make my dash out of small screens and use the RP as gps to give me speed, direction and related info on the screen.
Another problem is the powertrain from the newer truck has electronic fuel pump and will need electronic fans. I want to use the RP to read and display a few crucial sensors (engine temp, oil pres, fuel lev etc) as well as use these signals to trigger the appropriate motor ie fan, fuel pump.
My truck is pre obd 1 and 2 so I will be able to hand pick the needed sensors but have not seen anyone feeding the signal directly from the sensor to the module. Is this a problem and will I be limited to say 1 or 2 sensors?
I believe I will have to use an external power module to use the pcm signal to actually trigger related relays is this correct?
Is this something that the RP could handle?
Basically can you point me in the direction I need to go? I have some electronics and programming knowledge.
