So I had an idea the other day. Someone tell me if it's decent or if I'm off my rocker.
I have a DMM that has a serial port for data logging. I also have a laptop PC. If I were to tap into the sensors wiring harness, turn on the logging software and then log the voltages as I went for a drive would I get accurate readings. I could stash the DMM under the hood somewhere to keep the voltage taps short, then just run a serial connector to the firewall. I know that I could only monitor one sensor at a time, but I would have a nice realt time data dump saved that I could look at.
useful? Worth building? I've already got all the parts, it's just a matter of putting it together.
