SOLO SB 4600-11. ECU Firmware update, 19/08/2019

[Bill Tugnett]

I'm trying to establish whether this SB has actually been performed. As per the SB, I have installed the latest WinTrijekt Solo 1.43R16 on my computer & downloaded the new ECU firmware (V517R8). I follow the instructions 1 - 5, however the new software will not download. An error message tells me that the 12v to ignition coils must be disconnected - I did this by pulling the # 9 CB. I repeated 1 - 5 without luck -another error msg "Fehler; falsche Steuerung (= error; incorrect control?). Does anyone have an English version of these instructions (including the error messages)?  Any suggestions on what I may be doing wrong? Thanks,  Bill

I spent time on this during our (Aussie) winter. With the assistance of someone more computer savvy than I, they suggested  downloading the firmware V517R8 onto an SD card & uploading it to the ECU when requested at step 5. And this worked! Rgds, Bill
