I came across a discussion on the MR2oc forums about running an AFC on the 3S and most ofcourse completely disagree with it due to the fact that it causes very dangerous timing advance due to the signal "correction". The reason for this is because The stock 3SGTE PCME uses the airflow signal for more than fuel judgment. It also uses it for engine load. Which in turn causes unsafe timing advance.

My question is do you supra guys have the same problem. I was just curious. I just ordered a MAP ECU. Since this is a speed density system it will illimate that reading from the system correct? Meaning that since there is no longer an AFM it will get it's Fuel Judgement and Load readings from another source true? If I have posted in the wrong section I apologize. Thanks for you time.
