...or an 8.1 base file, with the same firing order/injector bank changes. From what I can see in the service manuals the 8.1 reluctor is the same as the LS.

Where is your 1x cam sensor gonna be...

I think if you are using LS crank/cam sensors and LS coils and LS whatever else, you'd be better off starting with a LS base file. Just change the firing order (ECM 14000) and injector bank select...

Well you're going to have to start checking and testing things, this isn't going to be fixed with a keyboard.

Right click, 'save as...'

If this is the typical ".660" dual spring with coil bind at 1.080, and your installed height is the typical 1.800, you should have enough space to add a .060" shim without binding. That would raise...

'Everything is basically new' means it all HAS to be good, right?

236/250-whatever is more than enough to go past 7500... with the right springs. I'm not sure a generic ".660 lift" spring with 140...

There are quite a few oddities in the early OSes. You can go to the repository and download all kinds of different files from the different years and check them out. They do all use VVE (they're...

Way way too many graphs. You need specific groups of graphs for doing specific things, don't have every graph you've ever thought up that might be useful one day and load them all at the same time...

It is being displayed in the channels list, and a log file by itself is nothing but the channels. If what you mean is that it's not showing up in whatever graph you made, then for other people to see...

The Galaxie is less than 100 miles from here, too.

It reminds me of another one I had way back, a '66 Chevy II, which was nothing but a shell with a 6-point cage, leaf springs and slapper bars,...
