Why not simply take off the RBE and see what happens? If the lights go out, contact RBE and tell them their unit has a problem.
Why fart around with parts that did not present any issues BEFORE the RBE?
My 2 cents (and we don't even have coins here)
After l fitted the more basic “Rapid Bike Easy” unit to my 2019 Duke 390, the check engine light came on after a few rides.
I took the unit off and after a while the light went out.
However the bike was so much smoother (at low RPM) with it fitted, so l emailed the manufacturer
They said to turn the fuelling adjustment (on the RBE) from +2 to +1
Which l did, and the check engine light has stayed off since.
The RBE still works with this adjustment to the settings.
I wonder if any similar adjustments are available on the Evo version.
It is my opinion: the steps of a RB install should be,
1) perform an ECU reset ( whether it be by idling for 15:30 or via the KTM ECU shop tool if available). This way the ECU is reset to a baseline without any learning? having taken place.
2)Install the RB of your preference (Easy in my case).
3) Start and ride the motorcycle, allowing the learning process to take place from a baseline with the RB installed.
It is my belief, and I can certainly be wrong, that us end users install the piggybacks after running our bikes for XXX amount of miles. The ECU has learned the operating conditions to that point. The piggyback is installed and when the bike is started the ECU receives a new signal from the exhaust sensor that is enriched from the last time it was started and then records a code causing a check engine light to illuminate.
Has your code returned? Mine comes and goes, and i only get it at startup and idle when it does come on.
