Rx8 ecu part number
I have a rx8 automatic 2004 model. And the ecu ‘s part number sticker is damaged, and i cant find the part number, where can i find it? I need a new ecu as my car cant remember the fuel trim, and whenever i hot start my car, car shuts off if i dont rev very slightly (like putting foot on throttle and pushing a hair line max)

This still doesn't sound like an ECU problem. Not learning fuel trims is not a thing, any more than your phone forgetting phone numbers. If a sensor is misbehaving, or the fuel trims aren't enough to overcome unmetered air coming in, you might see what you're seeing. But the solution isn't to replace the ECU.
What diagnosis was done? Are there any codes? Does it still do this after a drive cycle or two?
90-100 is technically failing if that's at 250 rpm. Should still run though.

any Mazda dealer can pull it up based on the VIN
here’s the appropriate thread as well

have no input on the actual issue at hand otherwise, but good luck …

I would doubt that it is an ecu fault. There are so many other places to look first
The ignition is notoriously an issue... and depending on the age of the car you can get O2 sensor issues MAF issues or other fueling issues that are much more likely
The compression being down doesn't help... sometimes when you have a low rotor the idle is the first thing that suffers... especially after a warm start when the extra fuel added for startup can wash out the compression even more.
I would check the plugs... and test the ignition with a HEI tester first. Remember that the trailing plugs fire first at idle... and make sure they are OK. They are cooler plugs and can foul much easier than the L plugs.

no codes, i believe if o2 sensor and maf was the problem,car would give cel

I would still check the ignition. I have seen new coils fail almost immediately. And plugs can do the same. At least pull the plugs and have a look. Often you can get an idea about what's going on by looking at them
You could also have an injector that is leaking a bit... it would be more apparent at idle
Best way to figure stuff out is to start at a baseline and check everything. You know the thing about assumptions...
