question about suzuki computers ?

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.

Dealer flashes it maybe ???  That's all the has me stumped  ???  Unless all the operating systems are preloaded, and then diagnostics are used for programming?  Hmm....   the trickery  :o :-/ ???  I'll make some phone calls early next week and see what people I know come up with.  They are computer manufacturers, but I"m sure during some type of competitive analysis or something they discovered the trick.  You know, some automanufacturers actually use sportbikes for reference.  They sit down and try and figure out how Suzuki squeezes 150 HP out of bikes, when they have a hard time building a larger displacement motor for the Escort or something like that, and they have no HP.  They actually use some bike motor designs for reference.  Amazing isn't it.  8)

Come to think of it, does every ECU contain the EEPROM (chip)  ???  Is it possible that when you order a brand new computer from Suzuki, you are only getting the computer, and then you have to order each chip individually based on the bike.  Two seperate parts maybe.  Computer is one, and then you order a chip to match the build of the bike.   That makes sense also.  Could be that way.  Who knows.  That's another way to do it, and keep the ECU part number the same.  The part number for each EEPROM is different.  Also, does anyone know if the EEPROMS are OTP (one time programmable) chipsets?  Never investigated in d epth, but it's possible to reduce cost.  OTP chipsets are cheaper, since you can only flash them once ,and once their flashed, either use it, or throw it away and buy another.  Good cost reduction there.  Big difference.   ECU EEPROM's use OTP chips  ???

I don't think it works that way. I think you order the computer box and thats it. There's NEVER been any talk of changing actual chips that i know of.

2000-2001 750 had different type of TBs with a cable actuated secondary butterfly control.

Don't know if that adds any insight

Dan, anything further on the datalogger?

Yeah, but development has kinda slowed down.  Mostly because of work obligations.   I was inteding to provide one prebuilt for the Wegman benefit, but that went south when I couldn't make it "easy enough" for the average wrench to install.  It still needs some tweaking to get to that point, and I don't have the mechanical support to help figure things out when needed.  I'm not mechanically inclined, so stupid things take me a while to sort out when an average wrench can do it in 45 mintues.  But, I'm still pushing forward, just really slowly.  I have a general idea of how it has to be for the racers, so I'm trying to get it there.  Right now, it may be just a little to difficult to use for the average person with no electronics/coding backround.   Working on translation tables right now to simplify commands.  Just simplifiying things for use more or less.   Still stuck on some such with optical pyrometers.   Getting crap readings for some reason  ??? :-/  I'll figure it out sooner or later.  ;)
