Injector data not correct. (I know, broken record... but it keeps being done wrong, I dunno man.)

The table that was changed isn't used, the one that is used wasn't changed from stock...

What is the fuel pressure? How long does it hold pressure after key-off?

No Bosch O2s in GM vehicles, ever. GM/Delco, NTK, Denso only. No Amazon Marketplace.

If it has stock 2002 LS1 injectors why was the Injector Flow Rate table changed? What is the fuel pressure in...

Did you ever answer if it sounds like a rev limiter when it stops pulling? Sounds funny, goes flat, maybe some popping/banging? Or it just hangs at that RPM and sounds normal?

If the injectors are what the number on them claims, and you have a return/referenced fuel system, and it's at 58psi base, and it won't run with legit data... do you think the problem lies in the...

Misfires read lean at the O2 sensors. O2s do not measure unburned fuel, they measure oxygen.

Since you just replaced the sensors I assume you've already worked out whether the harness is set up for case ground or isolated and made sure the new sensors match the harness?

It sounds like it could be anything that causes an open circuit on both sensor signal wires. Only you can narrow it down from there, when I look in GM service manuals there's no diagrams for a '54...

No closed loop because both your O2 sensors are flatlined at the bias voltage. They're either not plugged in, or wired wrong, or dead/broken.

In the editor, type CTRL+N. Type in '14000' or '12301'.

Explain how this is an intake manifold:

MAP also increases right when it starts doing whatever is happening.

Kinda cool, would be a lot cooler if it was $3000 instead of $4500, it's someone's abandoned restoration project (bad, don't like...

Do the smart thing and buy a subscription at alldatadiy.com, that way you can get good diagrams for anything you end up with and don't need to limit yourself only to what's been put up online for...

...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...

Other things...

What is the crankshaft end play?

Is the crank sensor OE GM or some parts store offshore garbage?

When it reaches the 6500 limit, what does it sound like? Like a traditional...

So PRC knows which springs that cam needs to go +6500 with heavy-ass stainless valves?

Is there a part number or something more than "BTR 400+", or is this just how the world works now?
