Ed,

I was = thinking of=20 trying that.  I couldn=92t figure out which bins are not = correct.  For=20 example, in my case, the bins go from 43-44 to 47-48 when it = jumps.  So I=20 didn=92t know if I should adjust the intervening bins (the ones it = skips) or one=20 or the other side of the jump.

It seems that = you=20 adjusted the receiving bins??

Bill, if you don't like = the idea of=20 using Mode 6 because it may cause an adjustment of all bins above = staging - here=20 is an alternative suggestion based on the way I coped with the=20 situation.

 

As I mentioned my engine = would also=20 bog due to leaning during the staging process - being too lazy to read = the=20 manual and spot Mode 6 as a possible solution, I used the "brute force"=20 method.  I observed that when my engine staged my bin pointer would = jump=20 from the 30 some region to around 60.  It was immediately after I = observed=20 the manifold pointer to make that jump - that the air/fuel ratio = went lean=20 and the engine bogged.

 

So from the lean = indication I was=20 getting , I presume my engine was (for whatever reason) not getting = adequate=20 fuel in the bins around 60.  So I started increasing the MAP values = in bins=20 60-65  higher (enrichen) in incremental steps.  I found that = each=20 adjustment richer in those bins caused the bog to become less severe = giving me a=20 comfortable feeling I was headed in the correct direction.  = Eventually the=20 bog disappeared and my bin values above 65 were not affected because I = did=20 nothing to change those.

 

You might want to try that = method -=20 but I would give Mode 6 another try by adjusting below staging and = checking=20 results above staging.
