Fueling Dongle

My 2018 690 Duke was a bit rough at low RPM (lugging the engine). Most of this is due to the large single power pulses and small/light flywheel. Some of it is due to a lean fuel/air mixture (not enough fuel to burn properly) at low RPM while the engine is warm. This dongle smoothed some of the jerkiness out due to the lean condition. However, the jerkiness that is associated with the power pulses and light flywheel remain - as expected. This is a simple to install, inexpensive mod that will give you a little more power range down low. If you want to smooth the engine even further, find a heavier flywheel.

To be honest I want expecting much out of something that claims to work so well and be so cheep, but I was wrong. This took all of 5 minuets to install and then did the 15 minute idle reset just to be safe and then boom. It's a completely new bike runs so much smoother increased throttle response, i'm more then happy with this product and would highly recommend to anyone!

Very easy install and solved a problem that has plagued we for a while. My bike stalls at the most inconvenient time like a water crossing so I got the dongle and so far it's all good.

Bike runs super smooth now, especially at low RPM, it no longer chugs like a tractor. Best value for the money.

It helps smooth out the low RPM throttle, where the factory map is the worst. No it doesn't do everything a PCV does, but its a cheap effective alternate. Noticable improvement in my 701 E with this dongle and a Wings exhaust

This thing is miraculous. Took all of 3 minutes to install and the results were instantaneous. Smooths our the low end at take off with no more stumbling or jerkiness. I was a little skeptical but after reading reviews all over the KTM forums I said what the heck. All I can say is that at less than 30 bucks this is the FIRST thing you should purchase. I am very happy with the Fuel Dongle and definitely recommend it to any KTM 690 owner.

It took me 10 minutes to install. Works like a charm.

I've put this in a 2019 Svartpilen 701 that I just got, and it works phenomenally. The bike in stock form is unusable in the 2-5k RPM range. This dongle helps a lot, making any RPM +3k actually useful.

If you've just got this bike, this is the first thing you should do to it.

With 13,000 miles on my ‘17 KTM 690 Enduro R the O2 sensor went bad. I finally decided to get the fuel dongle and plug and it made it so much smoother transitioning off idle. Now those slow sections of single track are much easier. Cheap, easy performance upgrade. DON’T WAIT!
