You mask a good point, but agqain its already been done, the Cad's have a
crank trigger system that is adapable to the LT1 format. 

This would alow you to uses some of the more exotic diagnostics.

Other alternitives are:
1) use a PIC chip to make an electronic converter
2) The cheapest is to re-write that part of the code.
