Yes I have a F.A.S.T. for my mustang. It's very limited by today's standards, but it does the job. It doesn't sound like you're fully up to speed with what the stock ecu can do. I would never claim it's the "be all end all", but it's more capable than I think is being represented here. I don't want to get into the weeds and start arguing point by point or anything, so I'll just leave it at that.
The mac is a little dated though, our ECU is more related to this:
I’m familiar with the stock ecu, its hacks and what it lacks.
Keep believing in it Sir.
Thx I will. Until a stand alone can pass smog, it doesn't do what I need. Just so you are aware the stock ECU is capable of a lot of the things you listed out. I'm not going to splain to you about though, you can look more into it if its something you care to learn about.

Faster logging and live adjustments have been accomplished through DMA. Personally I want to work on getting at them (and more) through the AUD (JTAG). I started a thread about it a while back. I'm just some hobbyist though, not a professional developer. So it takes me a long *** time to make progress on this type of stuff.

There is no reason to be running a stock ecu on a car that needs these injectors. ID2000's will make 1000whp with the fuel pressure turned up a bit. 2600's are another capabple of probably another 200-300whp. If you're concerned about emissions inspections to get tags, put small injectors in and keep the stand alone "plug and play" so you can plug the stock ECU in and go get the car inspected. The Haltech Elite and Motec M1 (JRR Firmware) will run great on stock trigger wheels, so there would be no mechanical work to changing ECU's other than changing injectors. And you can drive the car knowing your $17k race engine and $3500 76mm turbocharger are being protected from undue damage.
Tuning an 850whp Evo on the stock ECU is basically a joke, you get one, maybe 2 lines of datalogging per 1000rpm on a 3rd gear pull, no safeties, no closed loop fueling in boost, no per cylinder timing or fuel adjustment. It just isn't enough. The stock ECU doesn't really belong on cars making over 8-900whp. The super hard fuel cut rev limiter is hard on parts as well. I wouldn't even want to attempt something over 1000.
Theres a big difference in what something can do, and what it should do. Can I dead lift 450lbs? Yes. Should I? If I want to walk tomorrow as opposed to going in for back surgery... no, I should not.
I guess what I'm really confused about is if you have the $50k to put a car together that needs these injectors, how do you not have another $3k-$4k to put proper engine management in it?
Oh, and then there would be the fun of getting a big turbo stock ecu car to actually hook. Those big turbo's don't really have " low boost". Even with twin 44mm gates, they're going to make too much power for 1-3 gear on wastegate line. So not having DBW or, a method to control boost other than wastegates, or traction control, will be a huge performance hindrance.
But yeah, stock ECU would be fine other than all those huge issues.
you guys sure went meta on this question. OP asked "can" not "should". These injectors operate on a pulse signal just like all the rest, there is no reason the stock ECU can't send these a pulse just like any other injectors.
What is with this "no safeties" stuff...we all know you have to force the stock ecu to let you blow the engine up. Tephra added Wideband AFR monitoring with boost cut...etc.... just saying. I started tuning on a Barry Grant Mighty Demon, guess how many "safeties" or log files that generated. Got the job done just fine though.
