ECM complete removal

Having spent over two years looking for a CJ6 or CJ8 with Auto trans and full hard top that were priced under $20k and finding none.

I got a TJ Unlimited as I want the long wheel base.

TJ's are great with the coil spring but the Idiots in charge put a 42rle in them they should have left the 727 trans in them.

The 42 could be better but it certainly isn't the deal breaker folks try and make it out to be.
 
None of those things are PCM related and you've been correct twice so far, you are not a mechanic.

I don’t think I ever said they were related. But actually, some ARE related just like your crush is to you. I was simply stating that “these are the things I’ve done since I bought it”.
Thank you mechanic for your input and which wheel goes on the front?

You aren't very good at this.

Good to know the question wasn’t dumb! At least to the ones that had the capacity to understand the question.
I appreciate this, thank you.

Boom! Now this is a reply worth reading! Thanks man!

If you decide to do this and go down this path to build a non computer controlled TJ make sure to post up what you did and the results. Some of us here are also interested in accomplishing this.

The PCM doesn't stop you from spinning the tires. There is no traction control on any TJ from the factory.

Ok. Thank you. “Spinning a tire” was used as an example of how I do not want a computer to dictate the way I drive, not a reference to this particular vehicle. But I appreciate the time you took to attempt a correction in my verbiage related to JeEp specs.

And this response had nothing to do with the question. So thank you for the time you took in location the letters on the keyboard to type this completely irrelevant “answer” but it just doesn’t help. So go back to practicing tying your shoes and don’t offer a response to an already answered question.
Simply, the answer is “yes” and it was posted previously with links on how to eliminate the ECM
If you can’t offer a solution to the problem then there is no need to strain yourself and waste anyone’s time with a post.
Chin up buddy! Just keep coloring those pages

I absolutely will and I appreciate the response in reading and answering the question I had without any negative connotation. I salute you.
 
I'm not a mechanic either, but I'm going to jump in here.
First, let me say that Mr. Blaine is one of 2, (The other being Jerry Bransford), guys that you should listen to when he speaks. He's not a dick, but he WILL simply tell you what you need to know and not care whether you like it or not.
Second, our 4.0 engines simply will not run without an ECM. It controls the fuel, spark, timing, and everything else the engine needs to run.
Fuel: we have a fuel injected system. You'd need to replace it with a carburetor, along with a manifold and all the connecting linkage, because fuel injection does not have throttle linkage, it's Throttle By Wire.
Spark: you'd need a distributor, coil, and all associated wiring.
And that's just off the top of my head. To remove the ECM, you'd basically have to perform an engine swap, and install a 258 from a CJ, or an older YJ. Could it be done? Sure. How much time and money do you have. Because since you're not a mechanic, you're going to have to pay somebody to go it for you. And just as an aside, in many places, it's not legal to install an old engine in a newer vehicle.

There are lots of ways to do lots of things, but most of those are like peeking around the shower curtain at your granny. Just because you can, doesn't really mean you should. Can it be done? Sure, go back to late 60's technology and the bullshit that entails. If want anything solid, reliable, good levels of drivability, easy starts, with very consistent performance, that's going to take a computer and a few sensors. And while you may have intentionally overlooked my 700R4 answer, I know of a couple who have done those swaps behind the 4 liter, they never did get them right and these are folks who know what they are doing, not some hack who has never seen a dipstick except in a Jimmy commercial.

Minor correction to your mostly correct post. The TJ (all of them) have a throttle body that does have a throttle cable going to it.

The TJ PCM doesn't have any nanny stuff. No traction control, stability control, most don't even have ABS. It doesn't seem like you actually know what you're trying to fix.
 
So basically I would have another 91 YJ or 79 CJ like the ones I have parked on each side of this Tj now? Lol
I guess I’m wondering if I just completely took out the computer, what else I would have to do to it before I could drive it

You would have to replace the iPad (oil pump drive asst) with a distributor coil and ignition wires or build a crank trigger system for the existing setup. Replace intake and exhaust manifolds with carburetor versions. Replace exhaust or remove cat. Install an instrument cluster for the gauges or figure how to make a conversion module to send gauge sender readings to the cluster via a data link. Then figure out how to make the transmission shift if you have an automatic which would require modifying or installing a manual shift valve body or purchasing a stand alone shift computer to operate the transmission separately.
 
Trying to get rid of the ECM/PCM entirely is going to be far more frustrating than just getting the PCM fixed or replaced ever could be. 05/06 TJs are well known to have various PCM problems, a few of which are serious, but @Mark cantrell at www.wranglerfix.com can walk you through whatever issues you're having. Trying to get a TJ free of its PCM would be a lengthy drawn-out process, even the instrument cluster gauges are driven by the PCM. I'd definitely fix it with a repaired or replacement PCM from Mark. He's a good guy who won't try to sell you one if it won't fix your problem. He can even run your PCM on a 2005 model to test it for problems, and/or run his replacement PCM on that model to make sure it's working before shipping it to you.

And you're new here and don't know the various people here and while mrblaine is not one to spoon feed anyone or worry about hurt feelings, his thoughts and advice are 100% technically correct and spot on. You won't find a better resource for all things TJ related. Really. That you didn't like his responses or recommendations doesn't mean they were wrong, a bit thicker skin will help when seeking advice. Not all good technical resources will worry about politeness or being nice for the sake of it.

I was at Wrightwood Jeep Fest a few years back and a fellow had a Red Tj heavily modified Big Tires and lifted a bunch, that was powered by a Small block Chevy with a 400 trans.

There was no computers at all on it.

It can be done and has been done.
