Converting Carb to MPI EFI system

[A.O.A]

Hi there every one :)
its been a long time since ive posted my last post.
well I have a new job which is an instructor in Automotive Mechanics school, and my project for this year is to convert a Carb engine (Mopar 318 1990 and a small block chevy 350 1990[ TPI] into a Multi port injection{MPI} EFI system. I am really lost in finding a cheap and not easy method which I was looking for is an MPI intake manifold, I found some but the fitting is the problem, the main issue that I am going to drill the original manifold and get the Megasquirte EFI system (injectors and sensors) and install them, and I am thinking if it is possible to get any other vehicle's ECU and use EFIlive or any other method to remap this ECU and make it work with my setup. By the way there are many BOLT on MPI systems which are $2000+ which u can't let the students work on :) and the MegaSquirte (as the Tech support said) won;t give you or store DTC codes which we use to make the Students trouble shoot the Faults

I hope that you guys gonna share your knowledge and thoughts with me

thanks a lot
Best regards
