Nä, även om jag skulle vilja så tror jag inte det finns någon ÅF som "nånsin hört talas om detta fenomen".. Letar förbryllt efter service bulletin eller dyl.
Du en fråga, har du haft lös din knacksensor? Hade lös min i höstas och det skaju vara en massa klegg där inni som förmodligen gör att den känner av feldetonationer bättre. Tänkte om man kanske måste lägga i nytt sådant..
Men däremot har jag ev. funnit början av en annan trevlig bulletin, som ska hindra att varvtalet svajjar på topp och att maxvarvet sänks radikalt:
My dealer found that the electrical conections on my ECU and the pulsar unit were to tight. They repaired this problem and now are instaling an update from BRP. # 420665199 MY2006 this update deals directly with a cut out problem on 600 SDI as it will faulsely sence a hot muffler at 7000 to 7200 RPM if held there for a period of time or if you are in heavey going this will happen. It is a fault in the progamming and the ECU will over fuel to cool the muffler and some times go into safe mode. This causes the surging and cut out also a lack of power. This update was released in FEBRUARY. Hoping to go sledding this weekend I will let you know how things go.

THE MAPPING UPDATE THAT YOU ARE ALL TALKING ABOUT WAS RELEASED DATED FEB 08/06 FOR RPM Loss,Check Engine Light is named 420665199 file update MY2006 for muffler temperature control.
this is there fix for over heating of motor and exhaust.Now when the sled gets hot the light doesnot come on but it either retards timming or adds extra fuel.Then the sled when you hold it wide open will not rev, in my case 6700 rpms at 60 mph.if you stop and let it cool it will work correct again until it gets hot again.This is not a fix it is a patch.Ihave copy of this doc if anyone would like it PM me.
Slår man det art. numret på google så hittar man nån slags ECM eller dyl., $499
