I have a Screamin’ Eagle Pro Super Tuner (SEPST) black box version that I purchased from an eBay provider in Australia who sells them unmarried for my 2013 Sportster XL1200C. I bought a four-port cable to connect it to my laptop and downloaded the last available software from this forum (v.11.002.0000). However, there were no drivers with the software, just the program itself and the Vehicle Communication Interface (VCI) won't connect to the laptop. I get a beep as the USB plugs it and the VCI shows in Windows 11 Device Manager as missing drivers. I downloaded some other drivers for the similar orange SEPST (2109-08C) that covers more models, but these are not recognised as valid drivers when I try to install them. Does anyone know a work-around or where to download valid Windows 11 drivers for the SEPST from? Thanks in advance!

I have run the software on XP pro and 7 pro without any worries.

My son runs it on 10 pro.

If you got it from Mario, send him a message. He is good to deal with and pretty switched on to the electronics and software.

Thanks.

I’m pretty sure it is an issue with the drivers. It might even be that the drivers do not support a newer laptop running USB 3.1 / 3.2.

I’m not sure who Mario is. I bought the unit on eBay in Australia. 

They have been Orange since 2009, so most Screamin Eagle Supertuner Pro dongles are orange.

They ran like that until maybe 2017. Harley had Emissions compliance issues with them in the US and they were withdrawn

I have used the black dongle version on a few bikes, but all had had them from new in 2008/2009, already "married" to the bike.

My 2017 Software worked fine thru them, but It prompted an "updating" of the black dongle before allowing any reflash of the ECM.

That was not uncommon, fairly often the dongles had not been reconnected to the bike since new, often over 10+ years !

"Mario" was/is a Polish dude in Victoria, and he sold the "unmarried" or more correctly "divorced" dongles. As others have said, email him thru ebay, any dealings I had with him in the past were cordial.
