Clearly certain aspects of how the N54 works are being mischaracterized to fit in to your model of how you've tuned other platforms or how you think it should work. For example, you and clap135 continually ignore the adaptive timing system. Instead you say "well, if you set the advance maximums so low that it can't adapt up then you'll have tuning like you would in any other platform", and that is of course true. But no one does that and for very good reason. The adaptive advance system is one of the best things about this
platform. Timing is managed on a cylinder by cylinder basis and is almost perfectly timed in every situation, condition, and octane. It's never lazy or undertimed and never knocks. Try doing that with manual timing tables.

Also this has nothing to do with products. The fact is there are more tunes out there using the JB3s method of timing control than there are using CPS. It's about understanding how the DME and tunes work. I think clap135 put it really eloquently when he said if you add race gas and timing goes up its knocking. That seems a reasonable position and as I've said that will happen with any tune on this market. If you don't believe it then let's put that to the test once again. You'll be surprised.

You're right Mike. The ability of the N54 to protect itself in all conditions is quite impressive. Those BMW engineers really know what they are doing.

But...those same BMW engineer saw fit to reduce the timing tables in the IS version of the engine. Why would they do that if the system that they created was so good at adaptation that it shouldn't have been needed based on your reasoning? They increased boost in the IS and reduced the maximum timing allowed under certain load conditions. We are increasing boost even more with the aftermarket tunes, yet you suggest that we don't need to adjust the timing tables? I would think it would be prudent to follow BMW engineerings lead since they know the abilities of this engine and DME better than anyone.
