Actually the ECU does not think im flowing 440 levels of fuel (well it always does, but for all intents and purposes in this conversation it doesnt) it thinks im flowing 37% more since thats the signal being pulled. If i were to pull 25% it would be identical to a lex afm as far as what the ecu sees at least. The correction with the safr vs a stock lex afm is the same thing as far as signal is concerned.90Legend said:Bottom line is you need to introduce additional air into the system. The TCCS thinks you're flowing 440 levels of fuel when you're flowing roughly 1/3 more. The more extra air you can flow the less correction you need to make.
Though I could be wrong, I feel the less correction in closed loop is better.
