I work in automotive electronics repair, and have been for a few years now. This ECU looks almost identical to holden VZ commodores. We also see similar failures in Holden astras, bosch 5.7 & 5.3 ABS ECUs, etc. A lot of different vehicles use similar construction for their electronic modules.

The majority of the failures we see are related to the wire bonds between the connectors or mosfets, and the ceramic substrate. Often these are aluminum wires making connections fail, as the vibrate and over time will fatigue and break through.

We test for failed bonds by putting the ECU under the microscope, and very, very gently tugging on all the aluminum wires. if they pull away with no resistance, we know that's the issue and need to make a good connection to get the ECU running again.

There are also gold wire bonds used to make connections. These gold bonds are much more fragile. However typically do not fail, as they are not as prone to fatigue as the aluminum wire bonds. The gold wires are so fragile, that testing them will often brake them. Since they don't fail often, we do not test them.

To make a new connection, we cut away at the potting compound where the wire is supposed to attach. And clean out a area around the pads by cutting, and using tweezers to remove the potting compound. Being extremely careful to not disturb anything else. We scrape the remains of the failed wire away, and use a special solder to tin the pad on the ceramic substrate where the wire used to attach. Very low soldering temperatures. Then we can solder a wire between this pad and the connector.

This is very finicky and precise work. One wrong move can easily destroy the entire ECU. And even the heat from the soldering iron can destroy surround gold wire bonds, without touching them. Having the iron temperature too high, or using the wrong type of solder or flux can vaporize the pads you are trying to connect to. However, with a lot of practice, we have around a 90-95% success rate on repairing similar ECUs.

In the event a gold wire is destroyed during the repair, we can reattach to it. However they are much more delicate. And it is very easy to vaporize the pad you are trying to connect to if you get it wrong.
The wires we cannot repair are the ones that connect to the bare silicone dies on the board.
In the event there is a blown mosfet, we have a custom PCB we use to replace them. By milling away the remains of the blown mosfet, and running wires to attach to the ECU.

Very impressed with the bench setup here. Would be curious as to know more about the virtual engine test box. Who makes them and weather they are available for purchase?

Since Bosch made the ECU's I would wonder of they could remake another batch of them in order to provide to customers. Otherwise you'll need people who can reproduce the software and possibly adapt a later design or specially built ECU custom made for what ever vehicle that needs it. It would likely take hardware emulation to work with the rest of the car's systems, and that would be a lot of work if it could even be done.

Union Jack says:

Hasn't Hose already fixed this ECU about a year ago?

Lassi Kinnunen 81 says:

if it can start the car 40 times, why not use it for the battery in the first place ffs.

damn im so happy for you ūüėÄ

George Lucas says:

Motronic 7.3 ECU's are very common over here in Europe. I've got one in my Alfa 147.

rick James says:

Well long story short I fried my LS ecu and had a cell phone shop give it a try they told me it wasn’t there normal but was willing to give it a shot they was able to fix it the ecu is about the same size and looks the same as what you have and I know the part in cell phone are smaller bu I would ask them to give it a shot mine was damaged from terminals hooked up backwards during a jump start fried a few small parts and they was able to fix it

now wait a minute……..we have spent most of our adult lives watching this little pup fer rah we grow up to become an adult. the least you could do is allow its foster parents to view the young and fixed adult Ferrari a view of its majestic glory on the freeway hitting at least over 20 miles an hour. then take it on a trip by the beach or where there are a lot of people so that they too can marvel at such a technological wonder on four wheels. we need to see this green italian stallion on the road before it gets sold. yet due to all the thousands of hours of repair and the hundreds of thousands of dollars that went into fixing the Ferrari from hell….we the foster parents of our green italian son would like to know if you will be keeping it?

George Ngugi says:

Play at 1.25 speed. Thank me later.

Max Schrappe says:

Man, you need to clean and make it looking beautiful!

TiltyWheels says:

I take it something like a Haltec could not remedy this? I know Ferraris are finicky but besides all the normal gremlins a Ferrari has, its still an internal combustion engine. So could a Haltec just control those peramiters? Or even a Link ECU?

will Brown says:

A company will start to produce them at some point. But the price most likely will not go down…there just aren't that many Modenas in the world.

Advice Teller says:

Up grade ecu

Jair Corona says:

Finally Sam!

Zack Z says:

In theory could you not just map the layout of ECU to a schematic, open Eagle PCB, and redesign a standard PCB-based version of the ECU. If available, the cost of these older components would likely be low, the PCB ECU could be made smaller and more durable, and the cost of manufacturing is very low using a modern PCB manufacturing service like PCB way. The only hangup I would see is the flashing Of the ECU which seems like a non-issue for the company in the video that potentially has the software side mapped out. Just food for thought. Am I missing something here?

Micah Bell says:

Wow, i'm glad you finally figured it out! Grats!

Brion Flynn says:

Congrats on getting it fixed, it seems like it's been 1 year in the making, good it know there is companies that fix ECUs. Shout out to Jose.

jake lami says:

Is it a bosch unit or a siemins? Your best bet might actually be to take the image off your old ECU and run it on a standalone that emulates the original.

Even if you decide to replace your faulty unit it's only a matter of time before the replacement dies because something on that board is not designed properly…I highly doubt it's proprietary given Ferarri aren't really known to design their electronic systems in house.

I don't have one of these cars to test it on but if you're willing to send me a dump of your DME I might be able to send you back an image that will run on a standalone that will be more affordable.

Theodore Killmeyer says:

Sam, why are they not dumping the CPU micro code and use a FPGA to duplicate the ECU functions? it shouldn't be that hard…. especially the duplication that's been done for the Retro Computer community….. the hybrid Tech was dropped many years ago… they proved to be too costly…. an FPGA would do this job and the board design wouldn't be that hard.
