Yes, you are right on all counts. But, I do not know how to write computer code and I also do not want any expense such as buying micro controllers, displays or dedicated laptop computers or PDAs.
Indeed I have looked at the OpenGauge/MPGuino project.
I already have all the components needed for building about anything with analog electronics. I am just looking to build a meter that will tell me if I am at optimum throttle and speed with respect to the wind, hills, temperature, etc.
However, I could reconsider, so your suggestion is not out of my realm of thinking yet.
