Ecu Hacking Questions


I have been reading around trying to get an idea of what is going on. I don't have a degree in electrical engineering or anything so I might be a little slow with understanding this. What I understand so far is that you need to have a TTL to USB converter. Do this by making one like this guy did

or you buy one from bikeland.info

You then follow the a precedure.... dont know what it is.... and you connect the ecu to the pc once you do so you can reflash it with a file that you have modded using enginuity.

Now there is AUD connector... Is its only purpose is for me to read the ecu so that I can get a file to mod? If I can find a flie (download it) then I dont need to worry about the AUD connector. Right?


Please fill in the blanks for me. This stuff is very interesting to me. The ECU I will be hacking is a 06/07 GSXR 600 ECU. Which is a DENSO 32-bit ecu if im not mistaken.

So far it sounds like you have a pretty good grasp of what is going on.

You are correct about the AUD connector. If you can find a copy of the file for your ECU then you won't need to cut your ECU open and read out the code with the AUD port. BTW you will need different hardware from that pictured above to read the AUD port.

To fill in some of the blanks, assuming you have the file already.

You need to...

Build or buy the USB -> 232 -> TTL interface.

Figure out which pins on your wire harness are the programming pins

Get a copy of Renesas Flash Developers ToolKit (FDT) free software to flash the ECU

Find a map definition file for Enginuity/RomRaider. In addition to the ECU contents you need a second file the defines which map locations do what.

Edit your map

Flash your ECU

I think you'll finding the files you need will prove a lot harder than coming up with the hardware needed.

It is starting to look as if I will spend more time looking for files than I will be soldering. Any good places to start when it comes to looking for the right files? Or does it come down to you have to ask somebody for it. Are people pretty helpful when it comes to giving you files? How intensive is it to connect to the AUD port and hack it?

Thanks

As far as I know this is the only place such files are available. There are other sites with some files but most link back to here.

How easy the AUD is to read really depends on your background but even a complete electronics novice can pull it off with a little determination. You'll need to spend about a $100 at your local Radio Shack. I've helped people in Germany, Greece and the US do it. All were successful.

Of course once you have the map you will still need someone to write you a definiton file for it. Around here Petrik did the Busa and I've done most of the others but I don't do that anymore.

What does getting the definition file involve doing?'

thanks, your a lot of help

ALSO
I read you have to have a very constant voltage to run it and then a different voltage to flash it. Is there a seperate unit that is reqired to do this? Any links to build one?

and

will the hayabusa definitions work?
