ZZ 502 Ramjet programming
Just swapped a 502 Ramjet into my 4wd Safari. Engine runs well, but the tailpipes indicate fatter than necessary fuel mixture. Anyone know if there's a trick where you can decieve the o2 sensor into thinking that the engine's running mebbe 10-15% richer than it actually is? I remember reading somewhere that the 502 Ramjet was tuned on the fat side, I just find it ridiculously rich. Even the oil is black after 300 miles...
