James I like it! I would have NEVER thought of that.
Now I gotta figure out how big that is and where to mount it. It will have to be hidden fairly well. I love the out of the box thinking. It would be something to talk about when I show my boring stock 350 engine. As Spock might say Fascinating.
I will look into that as well as the speed sensor idea.
I was thinking about the speed sensor idea. I know that I can hook my laptop up to the ALDL and monitor output from the fuel injection computer. It shows the speed, and throttle position and O2 sensor readings. It also know what gear the transmission is in and other values.
Nothing can be changed from the fixed program, but you can see what is going on. I really need a motor-head 18 year old programming geek to figure out how to integrate all the readings just to turn a fan on and off.
