海外サイト引用ですが、お役に立てればと思います。 I trust you have converted maps to twin PTB format. Check Port on Computer is set to match port on software Also some Info I had given to me as follows The handlebar switch doesn't affect the uploading. 1) Uploading to mode 1 if you select mode 1 for fuel and ignition then the selected map is placed in the ECU in memory position 1. 2) Uploading to mode 2 If you select mode 2 for fuel and ignition then the selected map is placed in the ECU in memory position 2. 3) Uploading to mode 1 & mode 2 If you select this option there is no need for a handlebar switch because both memory placed have the same information. The selected mapping is send to meory position 1 and memory position 2. 4) Switching Ignition and fuel if you only select fuel or ignition, only the selected setting wil be uploaded to the selected memory position. Reading mappings from the ECU. This sounds a bit strange, but only the last uploaded mapping can be read back. So if your last upload is to mode 1 then it only possible to read back that mapping from mode 1, If your last upload is to mode 2, only mode 2 can be read back. so every time you change something in the mappings you have to write it down somewhere.
