You need an XDF for your bike/ecu.
I have two for the 900SS variants, which I understand will work on the 750.
There are two types of 15M ECUs. The A0 which is usually 2000 and earlier. The A8 which is 2001 plus.
The version is shown on the back of the ECU so you will have to undo the four mounting screws to get it out and look.
From memory the battery needs to come out first.
You need your bin file which you can read with the 15m version of IAWDiag.
Once you open the correct XDF first then open your bin file you can click on Tables, then double click on Main fuel, which is the horizontal cylinder.
The vertical fuelling is an Offset from he Main fuel, so just plus or minus small values and often zero.
That will show you the values that are in there and you can modify them, then save the bin file with a new name.
Then you write it back to the ECU with 15M version of IAW Writer.
They are here. Donationware like Tunerpro, so please donate

I do not know how to attach files here, so sent me an email.

Change the at to @ and the dot to . and I will send you he XDFs I have.
If you send me your bin file I can check if the XDF is correct for your ECU.
Also in your email tell me which country you are in. I am in Australia.
