Good thread. Just for anyone that wants to get a good speed sensor reading, this may be of help. you can even datalog it or convert it to a 0-5V output, activate devices based your speed, etc. It can read from 2 HZ to 20 KHZ. There are 2 frequency inputs (RPM, Speed, etc), 4 0-5V inputs, 1 EGT input, 1 programmable 0-5V output (based on 1 or 2 inputs) and 5 on/off ground outputs (programmable). Its a 7 channel datalogger, window switch, etc.
Those that want to read about it...
Smart Controller
This controller is only 3 inches by 3.5 inches and maybe 3/4 inch height.
I am in the process of taking my elise and putting in a carputer. I will be re-creating my own instrument cluster. I am still writing my custom software, here is a sneak peak. Please note that the gauge that says "FLOW" will actually be the speedometer. I will be integrating water temp, RPM, Air temp and a few other important goodies as well.
