The theory with E85 not showing N/A power gains is, the added fuel volume displacing more air in the port basically cancels out the extra power from the fuel.

The only thing definitive you could get from a resistance test is whether it's high Z or low Z, and if you've run them and the ECM drivers didn't go pop then they're high Z, which narrows it down to...

You can't ID an injector by matching it against a known coil resistance, both the injectors and DVOMs vary too much, and different part numbers are likely to be identical or similar enough that they...

Does it require a firmware update for the latest beta if you're only scanning with the beta but editing/flashing with the old release version?

You can install the beta and have Windows use the legacy editor as default and the beta scanner as default.

Well, 'enlarging' has connotations of it having been done properly, something I'm not sure applies to most modified injectors out there.

Correct values before whatever was done to them doesn't mean it will also be correct afterwards, don't assume yourself into an even deeper hole.

Why 8.1 injectors? Those are only 30lb-hr.

As for high IATs, maybe drawing in hot air to start with and then running it through a supercharger?

How much will the temp offsets change by embiggening a 28lb injector to 81lb, assuming you can work out they started life as LS4s?

No, in the file I posted only the injector data was changed, and the Cat/Post O2 tests that you can't get to in your version of the editor.

Yeah, great if you can work out the cross reference, and it's something with data available. Knowing they're OE Volvo injectors or whatever doesn't do much good.

Physically, all E38s interchange (the connectors and exteriors are the same). But you can't put a 2007 E38 OS into a '08-'09 E38 or a '09-'10 E38 or a '10-'17 E38, and you can't put a '10-'17 E38 OS...

The LS4 injectors are only 28.3lb-hr, if they're stock.

So they not only don't supply data with them, but also deliberately defaced the parts so no one could find legit data on their own? Fuck that. I'd find this company's location and return them, in...

Like a compression test, the spread between them is more relevant than hitting a specific exact number. Lots of variables in an ohms test and it's unlikely all 8 in a set will have failed in exactly...

But downstream O2 & cat codes have been turned off? Are they aftermarket/universal cats or the OE y-pipe?

(that's not the correct layout that matches your VVE, but just a general 'how things work' deal)

It's always going to smell bad without cats on it. There are things you can do to improve...

I don't put a lot of stock in weird offsets between events in the logs, unfortunately. Sure would be nice if it didn't consistently try to fool you.

Whether these things are a result of...

I think you are on the wrong track altogether, which can sometimes explain why you can't find info on others having done it before.

It always makes me happy when I make edits to someone's file and instead of using that file they try to copy over the changes I made into their original file, not knowing that there are things I can...

How would you put a stock OS back in it if you had one? Can't do it with HP Tuners, not on a Gen 4. Needs GM SPS.

If you don't have any idea what any of that means or why you can't do it, then...

There is no GM-format data for FAST injectors, they're made for aftermarket systems where none of that stuff matters.

Well that's not how you do that, use the one column from both tables that matches your base pressure (408kPa will be close enough for 58 PSI).

CMP counts did increment in the runs-on-starter-fluid log.
