your understanding of their theory of operation needs work.
what you SHOULD be focusing your energies on is identifying an additional 0-5v analog input to the ecu that is not critical for operation. this has already been done for a different purpose, that of logging wideband uego controller analog translated outputs.

The translator takes the k-type thermocouples output and "translates" it to a 0-5v output. That is what the stock EGT sensor input is. Why would I go looking for a different 0-5v input?
Also using the stock EGT input would allow me to utilize some of the failsafe features in the ECU ... ie: if EGT>1650* then put the car into failsafe mode, thus cutting boost and going to the failsafe fueling map.
