Motorcycle Tuning 2005 Yamaha YZF R6

Postby VX L67 Getrag » Fri Aug 18, 2017 3:11 pm

Howdy all,

Just wondering if anyone here has experience with tuning motorbikes?

I have finally got around to reading the file off my own R6.

The ECU seems to get identified as either Denso or Mitsubishi but it has the 3 diamond mitsubishi symbol on the front of it.

The file is only 128k but the xdf is almost as big so well defined although there is a lot of unknown maps.

The numbers on the front of the controller which are also what identifies it are 5SL-AO(they all have the 8591A as known between these).

2003 to 2005 have the same setup just the last 2 digits change depending on year model & country of origin.

Anyway to the actual question does anybody know if the VSS ratio is adjustable in the eeprom dump?

Hey VX L67 Getrag,

I'm currently in a similar situation that you were a few years back. I'm looking and reflashing an 05 R6T, mostly for decel fueling, tip in fueling, vss adjustment and fan temp control.

I have come across woolich racing who offer a product to alter the fuel and ignition maps but not the fans or vss.

Likewise Samios have on their website that they have reflashed an 03-04 R6S (

I haven't gotten to the point of getting the binary dump off my ecu yet but was wondering if you made any progress on this?

Any info would be greatly appreciated.
