Again, I love computers, I just dont think they belong in cars .
What other complicated machines we commonly use don't compooters belong in?

The last book I read they bragged about the old ww2 jeeps would keep on running. Guess they were magneto fired?

Does not count. While they operate similar, they are very different in use. Go get a mechanical CJ7 as a toy and drive it, have fun with it for a few years, and you'll start to understand just what computers are doing.
There's a reason guys will spend $20K swapping in a more modern computer controlled engine and trans into an old ride. I'm in the world of old cars, and I barely know anyone running points, and I'd guess about 1/2 of everybody now has also swapped from carb to some type of electronic (computer) fuel injection too.
I also understand you don’t want any negative feedback. Hopefully you don’t enjoy off camber wheeling. Even with an “off-road” carb. It sucks and I’ve owned several GM carbed trucks and tried to do mild wheeling. EFI swapped every one.

The number one reason for all the battery powered lawn equipment and stuff we have nowadays is purely due to folks not wanting to deal with carburetors. I have had a wide range of crap ranging from concrete mixers to weed eaters to chainsaws to wood chippers with carbureted engines on them and I despise every single one with a passion.
This, I had a CJ5 before this TJ and lots of times if I got off camber the engine would quit and restarting off camber was an issue etc. I don't have any of those issues on the TJ.
Not negative feedback Just, looking out for you. Maybe they make better carbs now?
understood, thats my exact plan with the cj-7
I know wranglerfix can fix them (within reason?) but at some point we're all going to be left with bricks in our driveway once the computer dies and there are no replacements available and the companies who repair them reach a point where its no longer profitable to do so.
There were a finite number of TJ computers created, and there are less working ones now than there were in 2006. I know wranglerfix can fix them (within reason?)
But on the other hand, I do wonder if it's possible to replace the PCM with something like a raspberry pi. I mean, the computer is just taking input voltages from sensors, doing some lookups & math, and sending an output voltage/ground somewhere else.
I'ts already been done using Arduino. Behold the Speeduino!! It's an open source that uses TunerStudio as the base program.

This seems like a better use of time & money. Looks like this post is the first time it's been mentioned here, guess I have to go down a rabbit hole.
I learned ECU's and tuning by building a Megasquirt 2 for my brothers 85 GMC 1500 back in 2014/15. That's when we started down the LS rabbit hole. From there we graduated to HP Tuners and now have transitioned over to the Holley Terminator system.
Assuming we all agree that there is a certain degree of efficacy involved, you also can't run your car without the proper number of tires and what do we do when something has a reasonable expectation for failure? That's right, we get a spare and most of us even carry one around on the back of the rig.its more so that computers in cars are a necessity if they are in the car. you can't run the car without them or temporarily disable them.
I realize we're all just shitposting at this point, but I feel like we're purposely missing the point. There were a finite number of TJ computers created, and there are less working ones now than there were in 2006. I know wranglerfix can fix them (within reason?) but at some point we're all going to be left with bricks in our driveway once the computer dies and there are no replacements available and the companies who repair them reach a point where its no longer profitable to do so. It's not hard to envision a world where good quality sensors are hard to find as well. I'm not so worried about it that I'm going to follow OP down this path, but it seems fairly reasonable to look into the future and ask questions.

If you were really that worried about the PCM failing, a few bucks, a few tools, and neato little box to toss under the seat would get you back on the road with a quickness. I can even give you the name and number for a nice guy who can hook you up with a spare, turn off the SKIM function in your current one and be done with this whole mess in less time than you've spent answering posts on here.
having no PCM ever would mean I would never have to worry about sending it off to get fixed, no matter how long that takes its still an inconvenience even if you can mitigate the downtime.
