Where. Is. This. Tune. File. That. You. Have. Questions. About.
This goes a lot faster with a tune file to look at. Nobody can see what you see without the file(s), nobody can spot and then point...
How did you convert it from 4L60 to 4L80, just flipping the Trans Type switch? No segment swap?
Oh, never mind. 'TBSS' intake, so I assume it's a stock single-inlet returnless rail? What did you do with the rest of the fuel system? Is this a swapped vehicle?
If it still has the original 2002 L59/'Z' fuel rails & regulator, your fuel pressure should be 51 PSI KOEO, all the data in the spreadsheet is for 58 PSI. That's not why you have a no-start, though...
So you're saying that someone edited the VIN/serial to intentionally make it look just like one that's got a problem?

The sucky thing about these Galaxies is they're rear steer, oil pan clearance is a whole bunch of not fun.

Are you now, or have you ever been, a Fiero owner?
Oh. Well never mind then.
There isn't just one, that engine RPO was used in several different platforms and a MAF table has more to do with the intake plumbing than the sensor itself or even the engine.

Use the file with the correct injector data. Open Alvin's file using 'Compare'. Do 'Copy Selected Differences' for anything he changed that ISN'T under 'Injector Control'.
Or do the opposite, open...
That injector number is what came stock in a 2001 LM7, is it not? It's an old number that GM no longer lists but The Intarwebs still remembers it, says it's the same 25lb'er that all those trucks...

If your fuel rails/regulator came from a 2002 truck, and those rails have a feed line from tank to rail and a return line from rail to tank, and there is a little vacuum hose going to the top of the...
If the PCM cane from the same truck as the intake and fuel rail and regulator and injectors, why would you need to be messing with injector data at all?
The reference to use for OE GM Gen 3...
Returnless/non-referenced fuel system in a 2002? What's the fuel pressure?
Yes but whatever data was provided you could just as easily got to by making adjustments based on how it behaved. i.e., it's just tuning, it's not hard specs that shouldn't be fiddled with like the...
Transient stuff is tuning stuff IMO, others disagree. But I've never seen an injector datasheet that includes anything about transients same as I've never seen one that includes a VE table. Just...
Because it's 2 credits for a PCM you've never written to before and 2 credits for the file you found someplace that came out of somebody else's PCM (yours is corrupt and can't be written to the new...
No because it doesn't work that way. A '.hpt' file is an ECM file and a TCM file combined into one thing. Changes you make to the Transmission side of things get applied to the TCM. You're writing...
No, the '05-06 Trailblazers both 5.3 & 6.0 were 24x/1x, they just have the Gen 4 block/knock sensors/conrods/intake manifold/etc., 2006 car LS2s were 58x/4x. GM never mixed 24x/4x or 58x/1x though...
24254909 is 2010 CTS-V, correct?
