The E6K is getting long in the tooth, that's for sure.
Since you're already single turbo it would probably be worth looking at one of the more modern Haltechs. I would also consider looking at newer injectors - that's some pretty old injector technology you currently have.

you're in a good spot, every ECU is better than the E6K. in fact you could probably go with a carburetor and it would be better...

If you're going with a new modern EFI it may be worth modernizing the injectors to have a quality setup that will be easy to tune and foolproof in the long run.

First thing to do is find a good, reputable tuner (there are good tuners out there, but if you cant get ahold of them...). From there, start talking ECUs, also, you may want to get familiar with the ECU application, in case you end up doing some sort of remote tuning/file exchange.
Do a a search on ECUs, see what others are saying about said ECU, and support from vendors/manufacturers. Can you find/download documentation/apps from the manufacturer website?
I went from a e6k to a ps1000. I've had the unfortunate scenarios where I had to send my PS1000 for repairs (TWICE, all my fault). The ECU is shipped to US offices, and in both ocasions, they sent the ECU to AUS. First time, turn around was less than a month, second time happened during Christmas time, and entire turn around was about 6 weeks.

The Injector Dynamics injectors, which are based on Bosch injectors, have far better spray patterns, more accurate, easier to tune, more consistent at high duty cycles, etc.

Getting a newer unit is the ultimate goal but for now I'm trying to get my car started with the E6k but having issues with the spark.....

I was gna say the Haltech Elite 1500/2500, but gracer7-rx7 brings up an excellent point. Doesn't matter what you run if nobody can tune it. If you want something a bit older but everyone can tune, go PowerFC. Other than that, I'd look into where you're moving in Texas and find the closest rotary shop to you. Then, ask them what ECU they recommend and are more familiar with? It's probably the most important factor of all I believe.

My older E6K at some point had issues with Spark, my tuner at the time (KDR/Speed1) did something to the leading (or was it the traillings?)coils, and got the the car running like that (dont ask what they did). When the E6k finally died, and I replaced it with the PS100, KDR/Speed1 literally removed the modified coil and dumped it in the trash LOL
E series was notorious for flaky/faulty ignition issues, I wouldnt invest a whole lot of time trying to figure that out, haltech wont even repair it anyways.

've heard some interesting stories, but i kind of wonder about assembly quality, some E6K's are fine, and some should have come with wing nuts so you could pull the engine without tools.
if you go back and so some reading, there used to be a ton of cars with broken dowel pin lands, and these cars tended to have old haltechs. its very very rare to find a broken dowel on a stock ecu or PFC

My tuner lives in Los Angeles, I live outside of Washington, D.C. I could schedule a tuning session with him and drive to my local dyno. All I'd need to do is connect my laptop to the car and the wifi, he'd share-screen in and run my laptop remotely, making all the adjustments from his office in LA.
Here is an interview with ShaneT (probably one of the best tuners in the world) where he goes over remote tuning. Skip to 12:30 if you aren't interested in his background and credentials.
The only real coordination needed would be dyno control and pedal input (if you aren't DBW).
My vote is to spend more up front for an AEM or Haltech Elite now, and save yourself the hassle and costs later on. Take this as an opportunity to get a NICE new wiring harness as well!!

After using an Adaptronic Select (Not really a modern comparison to the other two), an AEM Infinity, and a Haltech Elite, the Haltech has had the easiest set up among them and has the best software imo. For cheaper ecus, I think the Elite is the gold standard with all of the help files, community assistance, reliable hardware, and modern technology. One thing that makes it a little more spendy is needing to buy an external wideband controller, but I can imagine frying an internal controller integrated in to an ecu would not be very fun. There are plenty of options at this day and age to pick from and frankly I believe if a person puts a few minutes in to looking up how an ecu and software works, I don't believe it really matters what you pick as a tuner should be able to figure it out even if it's not the one they advertise for sale. Haltech, Link, EcuMasters (EMU Black now has rotary support), AEM, and Adaptronics all have comparably priced ecus unless you're willing to ball out on a Motec, Syvecs, etc...
Regardless what happens, this will be the best time to do it once and do it right imo.

Most modern ecu's are pulling in enough data on their own that distance/remote tuning is entirely possible! I'm not talking about old school flash-by-mail stuff either.

Yeah, he seems like a really solid and down to earth dude. I looked into him and he's definitely tuned a few rotaries!! Though you probably just don't hear about it on the forums unless it's in passing as part of somebody's build thread.

Alas, to be a fly on the wall when ya'll find out what world-class Motec tuning from ShaneT entails... not for the weak-kneed for certain. I now wear those knee braces all the time.

sevenstock is interesting like that, you hear about someone, and then you get to see their stuff run.
