So this is what I posted...

Really Simple.

So you are allowed to make incorrect statements and have people believe things that aren't true because your incorrect statements were off-topic !!!


You are sounding more paranoid by the minute.

The only "non-sense" here has been your posts.

The ECU can't be "cracked" in the sense the poster was asking about, many functions can not be changed at all, and the system overall is encrypted in ways that not only make it extremely difficult to try and work around, but would make it illegal under DCMA to try and reverse engineer your way around.

The post in question went on about some other issues that had been asked in the thread too, which I suspect you understand even less than these items, but the overall point being my post correctly addressed the questions raised by the thread, and you have, as usual, offered absolutely nothing of value to the thread of any relevance to the topic by posting in it.

Lemme help you out even! Here's the bit I was reponding to regarding the ECU:



Since you admit that killing the fusable links makes the PROM non-writeable, in what way would yanking the chips off of the ECU and reading them on other hardware help the poster accomplish what he is asking about?

What? It woudn't? Then why bring up being able to do so? Especially YEARS after he asked the question?

I'd love to see a sane and relevant answer to that...

Feel free to post another content-free rant though.
NO!! Get it right !!!

Again, in what way is which device you need to read the PROM (an electron microscope or an external PROM reader) at all relevant to the actual question asked or the answer given?

In either case you can't write to the chip, and thus can't make changes to it, and thus can't remove the checks for functions the car no longer has.

Thus, the substance of the answer was accurate, and the substance of every single post you continue to make is non-existent.

You also seem to not understand what the word "paranoid" means... kinda like you didn't understand what a "heat sink" was in the other thread... or understand that you were caught in a lie about having multiple positive reps about your posts in that other thread because you didn't realize others could see your rep and realize that wasn't true either.

So you are wrong again, and you then start again with your personal attacks.

So lets recap,

You were wrong, you didn't say anything about reading the ROM with a reader.... only you couldn't without an Electron microscope...

This is wrong, you realize it and are squirming like crazy again, with all sorts of non-sense...

Again, in what way does a change in the device required to read it have anything at all to do with addressing the actual problem the OP was asking about? You know, since reading it with an EM or reading on the bench will produce exactly the same amount of progress toward solving this posters issue.




If you'd like an example of actually, totally, and completely "wrong" though it would be for example when you claimed steel made a better heat sink than iron...because you didn't understand what a heat sink was.

or when you claimed you had multiple positive rep comments regarding the brake thread when anyone could easily view that you did not.

Or any of the myriad other times you've been in error about basic elements of fact.


Rather than address those, or try to do some learning so you'd actually have something relevant and correct to add to a future thread for once, you apparently spent your time scouring years and years of my posts, finally going back several years to find one in which the relevant part of my answer I gave was entirely correct, but there was an additional way in which one could have read the data on the PROM (which would in no way change the substance of the answer).


That's... frighteningly sad...

And kinda makes me think I'm gonna eventually need a restraining order involving you...



But again, do you have anything at all of value to contribute here? Anything that might actually help the folks asking the original questions in the thread?

And this has anything to do with what you wrote in this thread...

And this is not correct... Simple...

You don't understand what you write half the time, miss-quote what people do write and brow beat anyone that has any other opinion.

But you can't do that once the links are burned as they are in this case.

FYI, eeprom means electrically erasable read only memory... those you'd actually be able to make changes to, but aren't the ones being discussed in the Lexus ECU.


If you need any more basic terms explained lemme know!

(obsession might be a good one for you to learn!)

if you've got anything at all to post that would actually address the topic in the post, or in any way help anybody that has asked questions here, that'd be great too (albeit highly surprising)

BTW, did I miss where your magic bench somehow gets to read all the other ECU programming despite the encryption?

Because if not it makes your posts even less relevant, which I admit I hadn't thought possible.

Now you really are showing your ignorance.

You still cant swallow that you made an incorrect statement can you !!!

Of course once its programed its not changeable !!! Funny that !!

I was addressing your incorrect statement, and nothing else.

Let me remind you that you do this to everyone all the time.

How?

And please be specific, because it'd be great if finally had something of value to say here.

Specifically testing a memory chip on a tester or bench.

Nothing to do with Drug Stores or Magic..

I should've known better than to expect any useful information though... my bad!
