I'm interested too...
Going to be ordering either the tactrix cable or the Evo cable.
spent the last 4 hrs trying to track down a Datasheet for the MH6371F processors with no luck...
i emailed mitsubishi electric and hopefully they will gt back to me soon.
either way as of right now things arent looking too bright for the 96-97.5 EvoIV equiped.
will just have to wait and see.
if anyhting happens i would love to rewrite the code to used the MDP sensor as a MAP and add a IAT sensor and convert over
