Thanks for the kind words about the = EFISM, Jeff.  I think most folks will find that being able to graphically = see their fuel MAP/MCT makes it much easier to understand what your engine = is doing and how well your MAP is adjusted  – the only two units = offered  that are capable of doing this (that I am aware = of)
