A friend who is a Mazda shop service manager, said he heard that the full Japanesse PFC software instructions have been translated into English.



And that there is an adjustment that normally leans out the fuel when the TPS voltage has not changed for a while. This is suppose to cause that leanining out light stumbling condition that sometimes occurs when you cruise too smoothly for a while with our modded cars without O2 feedback control.



Does anyone have knowledge of this?????
