NA ECU upgrade options?
Seems to me there are limited upgrade options for the Turbo engine, and even less for the NA?
Can anyone point me in the right direction to research NA ECU upgrades?

The only NA option is the RTek, and only for S5.

Otherwise you need to go with a full standalone, which would be my recommendation regardless.

Not true anymore. Chris Ludwig (www.ludwigmotorsports.com) now has an S5 ECU that is programmable. You'll find him here as C. Ludwig I believe. He posted some dyno sheets over on IT.com. Not much to gain on the top end, but the gains he posted under the curve were tremendous and very worth it.

There is an S4 2.0 version now as well.

It allows you to alter fuel and spark, and other settings via a PDA. It's basically as close to a standalone as you can get without going to a standalone. You don't have to redo any harnesses or wiring work with the 2.0, you just have to send in your ECU and wait.

The 2.0 allows full control over fuel mixture and timing (independent adjustment of leading and trailing). It's standalone type control in a plug n play package. The ECU ships with the stock program in place and the user can then tune as they see fit to extract maximum power, just as they would with any standalone. 2.0 also includes some useful datalogging features and some other little nuggets of use. We've used the 2.0 on completely stock engines and full-race prepped ITS road race cars and have shown solid gains with both. See our website for dyno charts. www.ludwigmotorsports.com In short, the stock fuel curve leaves much to be desired.
The other versions of the rtek chips are no adjustable prom chips that are meant to allow swapping larger injectors in TII applications without overfueling off boost areas of the fuel curve. They don't provide for the same tuning ability that you get out of the 2.0. The reason they're not offered for the NA is that there really is no need for them as the NA injector is plenty large enough as it is.

You can also go with a Megasquirt, and there's even a plug and play version. Tuning it will be more involved than tuning an SAFC or Rtek, but it's more flexible and has more options, making it a more powerful system if you want to get more radical.

Why do you need to mod the stock ECU on a non-turbo?
If you wanna play with fuel and spark, just go full stand-alone EMS.
If you really want piggy-backs, AFC + ITC can give you what you want.
That IT-C is pretty rare, but it does pop up on eBay.

The stock box is already available in a mod version. The rtek gives you a lot more resolution than the AFC plus timing control of both leading and trailing not to mention some useful datalogging features. It's just a lot more capable system than the AFC and there is no wiring to fool with. At $400 it's cheap enough to compete on price point as well.
I've setup the same ITS car with a fuel pressure regulator under the old rules, an rtek, and with a Haltech. Using a fuel pressure regulator you can produce an optimum a/f ratio at any one point through the rev range. And typically you would optimize peak power. So peak power ends up being a push between those three methods of tuning. The rtek and Haltech can deliver more power below and above peak than the fuel pressure regulator alone by way of giving an optimum a/f ratio through the entire rev range. The Haltech (or any standalone) can't deliver more power than the rtek anywhere because they're doing the same thing at the same points in the rev range. So why spend more money unless you want the ability to control aux functions or want the expansion capability for later?

Well, racing usually becomes a matter of how much money you wanna spend?
The "ringer" combo is to stuff MoTeC guts into a stock ECU box and redo all the pinouts to match the stock engine wiring harness.
