Have You Ever Seen a Fuel/Timing Map Like This?

I have seen other posts where you have mentioned this, and I'm curious as to what type of problems you've had by leaving the trim limits at 20%. I just recently started using auto tune and I left the limits in their default settings. I figured whatever trims it created, I would accept them and over time the values would get smaller and smaller as the tune got closer to being dialed in. My first trim tables had quite a few 20s particularly in the 2% tp column below about 2500 or so rpm if I remember right. I thought it seemed a bit odd, but I accepted the trims anyway. All of them. I am considering reloading the original map and starting over with lower trim limits as you suggest, but I'm curious as to what exactly the thought process is. Also curious why you mention especially with cams? Even if I do lower the limits, I will probably still accept all the trims, because the way I see it, if I'm going to second guess the technology, then why did I buy it. I am an autotune newb, and appreciate any enlightenment you can drop on me. Now back to your regularly scheduled programming.

44 is for 2011-2013 heated O2's and DBW all engines 96 to 110
9 is for 2010-2013 heated O2's and DBW all engines
205 is for 2008 to 2009 non heated O2's and DBW
176 is for 2006 to 2011 non drive by wire.
141 2006 open loop
127 is for 2005-2006 open loop
105 is for 2001-2004
171 is for 2007 up sportsters.
The V-rod uses a lot of the same strategies
There are other strategies, but these are the main ones I have had dealings with.
Hope this clears it up some. The DBW strategies all use the %load kpa and the others use throttle position tables in the VE tables. All the spark tables seem to use the % load kpa tables and are pretty standard as to ranges.
