3)Do #1 first and #2 later

I say keep the JWT ECU or go to a system like AEM infinity, or preferably a Link G4+ ECU. A 64-pin SR ECU should plug in, you'll just need to move to a coil over plug igniton.

AEM V1 flat out sucks, and V2 is okay but tends to have a lot of problems with trigger issues and is generally slow in comparison with modern ECU's like Link, Haltech Elite, and Infiniti. My

Why do you say the AEM v1 sucks?

It seems like it's pretty much an OEM KA/SR ecu with more support for coil drivers and a map sensor. I know it's pretty basic especially compared to what's available nowadays, but I was under the impression that it would be more than enough for my goals.

If it sucks because it's unreliable and slow like an old computer from the 90's then I guess it is a problem lol

The biggest problem you will find with AEM V1 & V2 is support. They are both outdated & should anything become damaged on them, you’re screwed as there will not be replacement parts for them. On top of that, should you have a harness designed to plug into them, now you will have one more thing to replace. “Budget” & “Standalone” rarely belong in the same sentence.

You nailed it, haha. Serial cable communication takes ages, no live tuning, limited tuning flexibility, etc. It's just not something I would ever pay for. I would 100% run a Nismotronics board over V1, and probably V2. So that's another option for you.

Modern ECU's are awesome because the inputs and outputs can often be reconfigured, there's tons of compensation tables for everything you need to make the car super driveable and reliable, and you can tune them live because the processor is actually from this century hahah.

Megasquirt PnP. not a bad option for “budget” standalone imo. planning on purchasing one for my KA-T soon.
