Apparently you have some sort of data acquisition system , assuming you are measuring A/F ratio with a wide band O2 sensor . When on the 2 step , what is the A/F ratio ? Once you release the 2 step , what is the A/F ratio ? Is the A/F ratio consistent at 11.5 through out 1st gear , then goes to 12.5-13.0 after the shift to second ?
