I've had fuse 41 pulled for a week. 3 trips to and from work and about 8-9 start-stop cycles. NO CEL!!! All this really solves is the 1700RPM NPP issue. What you give up is on-the-fly changes to Engine Sound Management, so 100% open NPP all the time. V4 mode is unaffected.

I have only been operating in Engine Sound Management OFF. Not sure why it would make a difference in CEL if set to AUTO, but I wanted to mention it.

I like it better, but I can understand why the NVH guys may have done this. The bass resonance is noticeable in the upper gear tip-in lugging as described previously. However, I like it better as I can hear what the car is doing all the time.

So it -appears- that a LED spoof load fuse may not be necessary to prevent CEL. A simple relay control as proposed elsewhere may be all that's necessary.
