with check engine light permanently on.
We have two 790 in our group with rotweiler on it.
Both with check engine light. Now the guys fight to get the money back.
They have now install the akrapovic mapping.
No performance gain at all, but also no check engine light and all the drive mode features stay active.
Doesnt seem to be a no-fix permanent solution though but instead a temporary problem though.
"NOTE: With the purchase of a Powercommander from Rottweiler Performance we offer the O2 Optimizers for free below.
As of 4/23/19 we have dongles available, and they will work to keep the stock ECU from overwriting the PCV tune, but the engine light will go on. If you opt for a free set, that is all we have for now and will not replace this set with a free set once we have found a solution. We are making them available for customers who need them for racing or for tuning, but are willing to live with the engine light until we find the solution. "
O2 delete sensors that is causing the problem at the moment.
I will get it regardless of the light because you have tree different maps to choose from, standard setup, open slip-on and full system and easier to deactivate for the inspection.
EDIT:
"NOTICE: As of 4/21/19 we have achieved defeating the closed loop portion of the stock ECU for the purposes of running our 790 Duke Powercommander V maps and holding the tune perfectly, but we have not been successful in keeping the engine light off on every bike which we are still working on.
We are keeping these online and available for racers who are in need of them and do not mind the engine light being on for the time being, but want to notify our customers as such until we find a solution to the engine light.
We have decided to discount these parts 50% until we find the solution to the engine light but no refunds will be issued once a solution is found and if purchased at this discount.
All customers who purchased before this date will receive a credit for the solution or a replacement set if costs are roughly the same. "
