What is this diagnostic tool for a 355?

Not sure but looks to me like a test box, I bet all the holes are wired to the pins on the ECU connector. You then plug the ECU into one side of the box and the car into the other. Then as you drive etc you can use a meter to check levels between specific pins, attach an oscillascope or data logger to try to work out what might be wrong/right with the car.

Don't think its an SD2, they look "more intelligent" - LCD screen etc.

 

It's a breakout box. Either that or a waffle iron.


No, I'm pretty sure it's a breakout box.




Then again... did anybody bring some syrup?

 

Nope. Looks like the ABS test box (for 348 up through 1995 355) to me.

The SD2 looks like this:

Cool That's a Bosch 55 pin breakout box. It is used to back probe the ECU to do real troubleshooting. Do you want to sell it? Very few mechanics know how to use one. If you don't have a use for it contact me at [email protected]. I have used them to back probe into sensors like the Cam sensor to capture O-socpe traces on a digital scope. Then I don't need the SD2 idiot box. I can take sysmptoms and narrow down possible areas of problems an back probe the ecu while running to compare current to past scope traces. It is a quick way to pick out bad sensors. The SD does the same thing but is made for techs so they don't need to think. Most techs still just replace parts at your expsense and still get it wrong. Yup I'm a cynic. You have a very cool rare tool. Count the number of pins on your unit. I am not sure if the early and late 355's which used different motronic box have the same number of pins. I think they do. You can buy these from guys like Baum tool but so few people know how to use them that nobody buys them. Thus they are costly.

 

Actually... I think that's an ST05, not an SD2.

 

That would make for an awesome pictorial tutorial on the 348 Primer site (hint, hint)...

 

Now that you mention it, the original picture was labeled "Skilltester_058.jpg"

 

Sure....Get Chaa to sell me his box.

 

I know what that is...its an expresso machine...no, its a snow cone maker...

 

pin out break out box is the same thing . sto5 and an SD/2 are not the same thing . if you dont have tech literature to us the machines well ...... forza

 

95970072. About $550.

Common Billybob bid on it. You know you want it.

 

O.K....I'll try and get it on Ebay. Can you guys with 355 using the 5.2 motronics how many pins are on your ECU?

 

88 pins !!! This is the number of pins for a 5.2 Motronic. This item is a breakout box for Motronic 5.2 sensors and actuators diagnostic.

 

Resurrecting this to let everyone know I have two 55-pin (95970072) and one 88-pin (95972088), if anyone is interested.

It seems I have two different kinds of 55-pin break-out boxes. Here's one:

Here's the other. Anyone know what the difference is?

Anyone? Bueller?

 

That ECU connector doesnit look like anything Ferrari has used. Looks a bit like an older Mercedes conntector

 

Not sure exactly what its for but I am trying to make one for a 355, if you want to get rid of it let me know please

 

It is a Ferrari tool. I have one just like it. I don't recall what it fits. Most of mine have a tool number so I know what it is but that one does not.. I've used it just don't remember on what. There are a lot of break out boxes.

 

I'll take your word for it, just that connector to my eyes, looks odd.
