Al,

I apologize for the long posts.

In my opinion, the short answer to your question is YES.

The EC2 has the versatility to be tuned in a number of ways.  It appears to me, at least, that a significant part of the MCT corrections needed is the result of injector lag time.  There are at least two ways of dealing with this. 

One is to experimentally determine this for each address in the table.  This can be difficult since there are a lot of addresses and the corrections can be very different for adjacent addresses.  In addition, some of this tuning can only be done in flight.  Some users have more difficulty with this than others.  This may be because of the individual user or the individual equipment configuration or both.  At any rate, it seems to be a recurrent problem.

A second way to deal with injector lag is by including it in the calculation of the injector pulse width.  Doing so removes much of the MCT adjustments that are needed throughout the table and also removes the discontinuities.  This calculation is not difficult as demonstrated by the effectiveness of the hardware addition that I made which has no intelligence. 

Either method requires adjustments with modes 2,3 and, in some cases, 6.  The only difference in using the second method is that the entire table is nearly correct after these initial two or three adjustments.
