I hate to resurrect the thread, but what have we figured out is the "best" starting point? Should I stick with the DIY injection timing map on my MSpnpPRO until I have time to screw with it, or should I go with the "rev" map that I had been using on my MS3.

 

IMO the best starting point is to set it to end of squirt. Sweep injection timing at the lean limit for idle, and find the best timing there. Then apply it to the whole map. Sweep timing during steady highway cruising and then sweep timing at WOT on a dyno to see if you pick up any power.
