%Change to AFR Ratio Table Question! Ok, there are two tables to control the amount of enrichment the AFR gets at WOT...they are:
%Change to Fuel/Air Ratio vs. RPM at WOT
and
%Change to Fuel/Air Ratio vs. Cool. Temp. at WOT
Both of these tables show enrichment to add fuel at WOT of course...my question is:
Does one table compound onto the other OR, does one table REPLACE the other when values are met? For example, If I have 7.7% enrichment in the 80*C block on the %Change vs Cool. Temp Table, and then I have 3% enrichment in the 4800 RPM block on the %Change vs RPM table, does that mean that at 176*F and at 4800 RPM's my ACTUAL AFR enrichment is 10.7% at WOT for those blocks??? Or does the RPM table take over once its conditions are met, so say it runs 7.7% up until 4800 RPM's, then it drops to 3% until another change happens, or vice versa??
