Default 91-93 Lamborghini Diablo ECU Chips?

I saw these on ebay, does anyone know if this fixes the ECU problems?

I have never heard you can buy just the chips,
or if the chips are the problem in the first place

Exactly. Seems like a solution looking for a problem.

Those look like the chips, but can you really trust they work? Some ECU problems have nothing to do with those chips. Trust me, I've bought 4 new ones in the past three years.

It's insane that they charge that much just because they're for lamborghini. If you have the bin file you can burn your own eprom for less than $50 including the price of the burner. For a more common car a stock replacement chip would cost about $50 used, and the only real difference is the code and map values on the chip.

Austin your correct, but how do you get the information that is on them? Lambo won't tell you. Lamborghini doesn't even know what will happen when they run out of ECU's for the older models. If your a wiz kid, I have one bad and one good one as spares, you could make lots of $$$ if you know how to fix them.

Hmm, well if it's true that lamborghini doesn't even know what to do as far as chip replacements then there's probably some other complicating factor that I'm not catching on to. Normally you can read either the bottom of the chip or the top, underneath the label, to see what the model number of the chip is. Then you find a usb chip reader/burner that reads that chip. The good burners will come with basic software allowing you to read the chip, and you will get a .bin file in hexadecimal. You can then put a blank chip into the burner and write the .bin file onto the chip. Lamborghini would know this process though, and would have copies of the bin files, so as I first said if they really are stuck somehow then there's probably something complicating the issue that I'm just not experienced enough to know. Do you guys by any chance know what the engine management was for the 91-93 diablos?

Austin

example Moates chip burner:

I'd be happy to try reading the file off the chip and burning a new one, but if they really are as rare and expensive as you guys say then I'm assuming no one would be to eager to lend me one through the mail lol...

Austin - Your last question I think is the main problem. I don't think Lamborghini even cares, nor do they want to, regarding engine management and the repair of them in the older models. It is also impossible to get any information from them. During my restoration, I had several inquiries and the factory politely referred me to their vendor each time. You would be surprised how little they manufactured in the early days. In the case of the ECU units, the company is out of business, and from what I understand, they discarded all the equipment to make them. You would think that someone somewhere has a schematic of the ECU units for each model year.

Otherwise, from what you are saying, I can take one of my good chips and copy it as long as I have the correct blank chip and a burner? Is there any chance of the chip getting erased or damaged during this process?

I guess this would fix the chip problem. However, from my experience the units are made of more than just chips. Further, I have looked at several units and they are not exactly the same. Some have different chip numbers, wiring and circuits. For example, the two ECU units in my car work fine, but are not exact duplicates of the units that went bad. You would have to know more information regarding what each unit did for each model year to definitively know and how to fix them. By time you figure this out, I would have installed an aftermarket ECU and waved goodbye to future problems.

Just reading this tread, I want to point out that the programming referred to is for programming the ROM chips. While these can be copied and programmed as described and may fix the problem. The problem may be in the CPU or other support chips of the LIE computer. Hate to say it but if it is these you are screwed. Without a circuit diagram and specs it will be difficult to replace them. Does anybody off hand know for example what CPU the LIE computer uses?

The LIE's in just the Diablo went through at least 4 major revisions with differing chip sets.
