LT1 computer for TPI
since the LT1 coputer/ electronics are more easily programmed.
Is it possible to just cut the wires you dont need and use its computer tonbetter tune a car?
or is it cheaper to buy another ECM?
What ECM solutions are out there?

This has been talked about before a few times you need to do a 
There is no easy way to run a LT1 ECM in our cars. The LT1 ECM would be looking a signal from the opti-spark distributor which is completely different signal from HEI. Unless you are really good at source code the answer is no.
Just go to the junk yard and get a 730 ECM for $30 and call it a day, and if you are not running a 730 ECM right now then there is a tech article on how to convert to it.

A few people have mounted the Opti guts inside a conventional distributor, so as to be able to use the '8051 LT1 PCM on a regular SBC.
But with an emulator, or a Prominator, a '730 is faster and easier to program, and can even be tuned on the fly, which currently isn't possible with the LT1 PCM. Plus, you don't have to worry about locking up the PCM if something goes wrong during the programming sequence, which is definitely no fun (a concern unless you're using a bench harness. And spare ECMs are cheaper, too.
