The bike was wild before but this just makes it better! The Rottweiler fuel dongle brings the 701 closer to the bikes full potential. Rottweiler's Fuel Dongle: www.rottweiler...
I had one of them and it did a decent job on my Svartpilen 701. Replaced it with Kev's Mod and noticed an even bigger improvement in low speed engine performance. Smooth no jerking or shuddering.
no, it should automatically force the computer to run more rich. Mine is a 2022 and I have noticed a stronger fuel smell from the exhaust as well as less stalling.
Dont know if this is still relevant for you but if you got a Euro5 bike you need a different dongle. US huskys are all Euro4, there for its the same dongle for the lot of them. But EU bikes differ. I think 2021 and up is Euro5.
