I ran an AFM/DLI GZE for three years without an o2 sensor in my MR2, the best I ever saw out of a full tank was 205 km (40L)
That motor's dead now, lesson learned: if you put a bigger crank pulley on your GZE, make sure it's LIGHT!!!!! My solid steel 165mm pulley almost broke the crank snout off, and irreparably damaged the crank key slot...
