question about suzuki computers ?

[Steviebee]

I have a computers (spare) i got off ebay. Theres 2 sets of numbers on it.

32920-35f30
112100-0561

The first one is the part number.  On ron ayers it lists this as the control unit, for 750s and 600s.   2k -2k3 .  But what is the second number ??

Reason i ask is the other computer has
32920-35f30
112100-0560     (not -0561)  

I want to make what the computer is before i try to sell it.

Any crack suzuki mechanics out there that can anser this ?

It could be a number of things.  Manufacturers sometimes put the build run numbers on computers.   Different numbers can mean different flash files or operating systems.   Depends.  Best bet is to contact Suzuki or the ECU manufacturer instead of a mechanic.

could be that one is from a 600 and the other from a 750, or maybe they're from different years? just a guess.

     If I remember correctly they made a significant change in the computers after the 2000 model (or was it mid 2001?). One of them may be the earlier model which may be listed as usable for the later models?

[Steviebee]

wouldnt they change the part numbers if it was a different computer with a different tune ?

its the same part number listed on ron ayers for the 2k or 2k3  750.  ??

Not necessarily.  The hardware from 2000 to 2003 could be the exact same thing, but the operating system (flash file) could be and probably is different.  The operating system sometimes doesn't affect the part number.  I'm not too indepth when it comes to those type of computers, but you can always see if you can find the right flash file and program it yourself.  Dealer maybe?  Not really sure to be honest with you.  But, more than likely, it's all the same with hardware, with different flash files. That's how alot of the ECU stuff is done.

You could also see if you could contact a fuel injection company such as FIM in AU and see if they can help figure it out with you.  You may be able to just purchase the computer, and then send it to them to be flashed with the operating system and possibly handle any performance mods at the same time.  I'm sure someone has to have the original source code, or an "upgraded" flash file from the original.

I will ask my Suzuki instructor and get back to you with a definate answer when I get back from school.  The last set of numbers usually indicate how many times that part has been revised and how many times the supplier for that part has been changed.
Like I said, I can give you the exact answer this evening

If the part # is the exact same, but the program different, then how would the part get distributed properly? Suzuki parts come ONLY with a part # on them, not what year/model bike they fit.

Not really sure on the process of bike manufacturing, but I'm assuming each bike is done by "build runs" where they make one specific model on a certain date.  Not sure though  ???  We use the same computer boards all the time, and based on the BOM (Bill of Material) for the final produt we will be shipping, we flash the computer with the operating system accordingly.  For instance, we know that we are building units for company X from January 1st thru January 5th.  During those days, the only flash file we are using, is for that customer, but we use the same "core components" for several different customers.  This really helps in mass production, primarily because the hardware is the same for a few models in the line, and the overall quantity is higher for one specific part.  Same reason companies like GM use the same parts on different vehicles, and use "platforms" when building and designing.  Look at all the GM trucks and Vans.  They all use some of the same parts. So, the overall quantity brings the cost down.  Could be different regarding bikes, but I'm sure there are tons of similiarities in mass manufacturing in general regardless of the product.  It also depends on when the ECU is actually flashed, and put in the bike.  I know from my own personal past problems, that I recieved a Ducati 749 with a 999 ECU in it right from the factory.  Bike ran like crap, and we spent 2 weeks trying to figure it out. Finally had the ECU replaced with an Ebay bought ECU, and it ran perfect.  6 months later we found out it was the wrong flash file, because the ECU's were identical.  Just the operating system was different. Then, along came a 999, so we tried swapping the ECU, and the one from my 749 worked fine in the 999.  Go figure  :-/

another thing to think about is that chances are, Suzuki doesn't make the ECU for the bike.  Someone else does, and ships it to the factory on pallets or something and it's labeled.  They might say to their supplier:

We want 40,000  ECU's part number: ABCD

10,000 with flash file A (gsxr600)
10,000 with flash file B (gsxr750)
10,000 with flash file C (gsxr1000)
10,000 with flash file D (gsxr1300)

But, when it comes down to it, their overall purchase quantity is 40K pieces of part number ABCD, and that's the volume they pay for, because the flash file doesn't really matter in the whole financial scheme of things.  Regardless of the operating system, it still has to be flashed.  Won't take any longer or any shorter time to do it.  All the same thing with different perimeters.  Those ECU's could just show up on racks labeled part number ABCD version A and based on that, the assemblers in the plant know what rack to go to for parts for what bikes.

That's my thoughts on it. Most manufacturers don't make their own parts anyways.     :-/

[Nate R]

Right, I can totally see that case. I doubt Suzuki does make the ECU.

 But, in the case of REPLACEMENT parts, if they're all part ABCD as far as the Suzuki part #, then there's no way to tell which order gets which version.

If I ordered 2 ECUs, one for my GSXR600 and one for my 1000, and they WERE the same part # but different flash files, there'd be no way for suzuki to know which one to send.
