replied to the thread STFT Banks 1 & 2 - What is normal ?
" No, making it more rich will make the additive value in MS come down from high positives, and multiplicatives will lower the percentage..... positive on either one is the DME adding fuel, negative on either one is the DME removing fuel.
Zero on either value is what you are shooting for (perfect) because that means your main map is on target. the additives and multiplicatives are there technically to adjust for fuel octane differences, elevation, air leaks, restrictions and wear.
sounds like the beginning of WOT area on the map needs more fuel specifically then.
edit: looking at those logs, 20-30% positive needs to be corrected, IMO. The car is adding 20-30% more fuel over the entire fuel map to compensate. On any normal car, this would totally set codes for those being out of range, and would have done so around 12-15%.... "
