It seems like the transmission sensor outputs a sine and the speedometer output a square, so you cannot run the fuel injection directly off the transmission sensor. Ari (on the 9k) board indicated the transmission sensor is 4x the frequency of the speedometer as well, so there is major incompatibility.
I am now trying to find out if you can isolate the circuitry from a 9000 to do this function. I guess a need a 9000 speedometer to take apart. And an oscilloscope to find out if I did it right. :)
Nothing is easy, eh?
