Programmable Standalone ECU

This will sort of open up a can of worms for a street car. For starters, you'll have to figure out a way to pass emissions in AZ. There will need to be some integration with the rest of the chassis in order for everything to work correctly like it did before. Not that it can't be done, but it's something to consider. The fact that it's a 2.5 chassis makes things a lot easier than an earlier car because there is almost no CAN integration. If your car has cruise control, you would lose that feature, and you would have to do a few things to make the AC work correctly, but it's nothing I haven't done before. It honestly wouldn't be too difficult, just a bit of an investment to do it correctly. For what you need to do, an AEM Infinity 8 would get the job done. It's pretty good hardware for the money, and very capable.

Is this something you are wanting to tackle yourself, or would you be having a shop do the work?

If a plug and play solution is what you're looking for, there isn't one.

Passing emissions in AZ isn't a problem.
Both AC and Cruise Control work with my current bench flash. I don't care so much about cruise control, but AC is a must in AZ.

Ideally, I would want a shop to dyno and tune my car as well. The car runs extremely rich currently.

I like your stand-alone ECU project .Would it not be easier to resolve the rich running problem ? If that is the only problem,it may be easier to solve/hack than a stand-alone ECU?
For example, could it be as simple as using different injectors and using the correct air filter? Or just getting the injectors cleaned and maintained - easy diy job.
