[Diy_efi] New List Subscriber with Vague questions

The Holley Pro-Jection system isn't all that difficult to tune.  It's pretty
close to being a bolt-on operation.

I bought the 4Di version, and it works well.  It runs fine in closed-loop
mode (steady state) without any tuning, and isn't difficult to tune.

If you don't want to mess with an old laptop computer (a 386 will work
well), you can get the 4D version and tune it with the knobs (five of them,
I think).
