Corvette ALDL Datalogger (with Raspberry Pi!)
I'm curious if any nerds like me on this board have considered making a Pi-based datalogger for their C4. I'm thinking something that has a connection to the ALDL port and possibly a screen to display data, as well as logging the data to review later on the PC. I found a project that looks like it was designed to do that here, but it's pre-configured to an LT1 so some work would have to be done to use with an L98. Is there any interest in a project like this if I were to work on it further? Or has someone else already done the work? I'm lazy and don't want to re-do work lol.

You’re correct to identify that TunerProRT and an ALDL adapter is a great solution for when you’re working “actively”. My interest for a project like this is to constantly datalog. I’ve been building a 1994 G20 van lately, and my ultimate goal (which I didn’t describe fully above) is to have a Raspberry Pi running Ignition Maker Edition with a custom Device Driver (via a custom module, starting point here) to talk to the ALDL port to get all of the diagnostic data. Once I’ve got tags in Ignition, I’ll be able to do a lot of things using that platform, history capture, building custom UI’s.. In the end, I’d also like to (learn, and then) apply some machine learning aspects to things.
To circle back on the original question, I think this objective is only different in that it is expected to be logging constantly and in the background (via a low-power device that can be easily squirreled away (“installed”) in the vehicle).

This would be awesome but it would be much easier without Raspian. Instead of a Pi, consider an Odroid. The reason is they run Android natively instead of Raspian and cost about the same with the same form factor. There are tons of diagnostic scan tools that run off android and have data logging capability. I use an OBDLink in my car but that's for OBD2 stuff. Either way, going with a single board computer running Android may be easier than Raspian.

Dynamic EFI is an option, you send them your ecm and they mod it with flash memory, USB, enhance some other stuff. www.dynamicefi.com

No. It's just a single board computer like a Pi only it runs an Android operating system instead or Raspian. I use an Odroid C4 to turn my living room TV into a 60 inch tablet, that can be controlled by a keyboard and Xbox controllers. I use it to annihilate my kids at Street Fighter II. Basically it can run any Android app.

i like raspbian though because it’s easy to automate everything and run custom scripts.
i am actually working on another setup to create a custom dash panel that can be used to replace the digital dash with a modern lcd screen, running on a raspberry pi. Unfortunately the problem, as always, is time.
