Thank you. Now I understand a little bit more.
But what are the values in the EGR Table? Percentages? Absolute Values? Factors (most probably)?
It seems to me the lower theses factors are, the smoother the map becomes. Why?
What are they doing with the map?
And: How can I manipulate them to get which result? How do I know How far and in which direction I have to change them. How do I see the effect?
The VE Tables are not directly changed, as far as I see...
By a short review I found out that there are (at least) 3 different EGR Tables (front) in use. I name them after the first number: 2.001 (which is used in all of the latest maps), 1.656 and 1.484(this one is used in your example as result of a certain calculation). It seems that these tables are constant within a group of Maps (e.g. "2008-2009 DBW touring Closed Loop"). Why did you change them? what is the really different characteristic between these groups, as exhaust or inlet or the engine itself did not change very dramatically? Different Cams?
The 1.484 EGR and the 1.656 EGR are used for nearly equal engines:
You use 1.484 (CAE176-03-A0.mt8) for "Application: 2007-2011 'All Market' Shotgun / Shorty Dual Exhaust with O2 Sensors, Configuration: 1580 A/C only, Build Components:-- A/C and Breather Kit".
The 1.656 is for (CAA176-03-A0.MT8): "Application: 2007-2010 2 into 1 Exhaust with O2 Sensors, Configuration: 1580 Stage 2, Components:
-- 25 deg Injectors, -- A/C and Breather Kit-- .550" Lift 211/235 Duration Camshaft-- RB Racing 2 into 1 Exhaust"
Does it mean: the hotter the engine, the bigger the numbers? Or the more gas reversion by open exhaust, the lower the number(more probable)?
And how does the effect of the EGR vary with MAP kPa? (I understand it technically, but how does it work together with the VE-Table)?
