The setting for fuel cut determines at what TPS when the system is in open loop that it will assume the car is DFCOing right? For example, if you have it set to 24, whenever the TPS is below 24, and the car is in open loop, it will display 9999 instantaneous MPG right? That being the case, how does it differentiate from when the car is in open loop because it isn't warm yet? If idle is like 20, the car would be in open loop while warming up, and the SG-II will think it is DFCOing? How do you avoid this problem?
