Yesterday I got reminded that not all the GND:s (in busa) are connected to the same ground - therefore ecu may be picky which gnds to use when out of the bike.
When asking a question, you can also consider posting it to facebook:http://www.facebook.com/ecueditorcom
I started building my interface today and noticed a few things. #1 My ECU has alot more pins than the one pictured above, like 34 in each connector. Why is this?
#2 The wire colors in the yosh conector all match except for the wire that you have as dark green, on mine it is brown. I traced it to the ECU and it is going to pin 24 so I guess it's right maybe the color is just listed wrong? My yosh connector has 6 wires: black/white orange/ white white brown grey white/red
The white and brown I know go to the USB cableThe orange/white is powerThe black/white is groundThat leaves the grey and the white/red. Are these the ones I can pullout of the ecu plug and reinsert into the pin 25 and pin 28 locations?I looked over the wiring diagram in the manual and can't find wherethese 2 go to so i'm assuming they are just for the yosh connector.Once I move these wires, then I can wire the switches and usb cable incompletely at the yosh conncetor, right? Can I leave it on the bike allthe time or do i need to disconnect it when I'm not using it? Thanksguys!
Thanks RR, thats why I put it on here before I wired it up. I was just using the wiring diagram at the top of this page with the info from Jetspeedz 05/06 US Gsxr 1000 ECM Flash DIY w/ lots of Pics.I wasnt sure if when wired to the bike there was a difference considering everything else is still connected to the ECU. I have only bench flashed so far using a switch at FWE and reset switch at ground.
If you could check out the new diagram that would be appreciated, hopefuly I understood your suggestions. With the new diagram will I be able to simply plug in to USB, turn on 12v power supply/bike ignition then connect with FDT?
Thats strange, it shows up when I click on it! I will attach again. Also are the pins correct?Thanks
Question for anyone who is able to answer, I have a bench harness for a Gen2 busa, from what it looks like to make my Gen2 busa bench harness work is move the following pins from the hayabusas setup to the gsxr1000.Pin 30 to pin 7 (Rx)Pin 7 to pin 24 (Tx)Anyone able to confirm this?

Move 30 to 24, leave 7 where it is.
Worked like a charm, thank you sir!
