Running a Mapecu3 on my distributor big-single turbo sc300. Still on stock 95’ california NA ecu. Having trouble keeping afrs consistent, but someone told me I could unplug o2 sensor number one and it would allow me to tune just using the stimulated airflow through the mapecu and not have the stock ecu fight the mapecu (if that’s true?) Let me know thank you.
