Currently have Big Stuff version 1, thinking of going to Big stuff 3..any input

[87GN 98GTP]

My big stuff 1 twice has had problems connecting to the lab top so Im thinking of going to Big stuff 3 now,
1. will the current wiring work? if anyone knows
2. Is there anything I need to buy(besides prob getting rid of the msd and go to ls1 or 2 coils) anything else like Ive heard the crank sensor issues?
any other input would be nice

You may want to contact your BS3 dealer if you want to swap to LS style coils. I am pretty sure it's going to take a complete rewire along with many other changes. Bailey's new ignition box will probably be a better option
