I have rode several times this year and was getting a DET 7 code on wide open pulls lasting longer than 5 or more, it did this maybe 4 times where it sent it into limp mode. I didnt think this was going to be a serious problem because it was still hitting 8200 and pulling hard. However i brought it in because the problem obviously needed to be adressed. I live 50 miles from the dealer so i called them to ask what the code i was getting was, they told me it was high/low voltage to an injector. Well apparently i had low engine compression in the mag side cylinder, and damaged crank bearings. They have been handeling my warranty claim HORRIBLY. It is still unclear to me why i was getting this engine code and why this caused my engine to fail. Does anyone know anything about the DET 7 code? The sled has 1400 miles on it, i thought i was pretty easy on it, as i was scared to hold it wide open for too long with the qd belt. Pretty disappointing, my m8 made it 4k with no problems....
