I could use some help setting up my base tune for my 0411 swap on a stock 1998 L29 454 manual 4x4. I used excel and converted the MAF and VE table from the black box to the 0411 pcm. They look to be a good starting point. Now what I could use help with is the injectors settings and spark table.
Now I have the injectors data from the black box. It has some of the data needed but not all of it. What should I use when I don't have the data? Current injectors are 17113221. It also uses a manifold reference fuel pressure regulator. Should I just upgrade to stock ls1 injectors since the values are known? Below is the injector data from the black box.

Now for the spark table I'm going in blind. I can't use the black box table since it goes by map instead of cylinder airmass. Should I use a L31 (5.7) or L18 (8.1) spark table? Now ideally if I could get a tune file from a L21 (7.4) it would answer a lot of questions, but I have not been able to fine one.

So here is what I have got so far. MAF and VE tables changed. I also did a segment swap for the 4x4 and manual trans. Still need injector data, a timing table and to shut off some engine codes.
