[QUOTE="ajpagosa, post: 1316466, member: 30139"] Yes it is, I was surprised by that too. What is also interesting is even with those "rich" AFR's, the DJ maps 001/002 are much LEANER than stock in places (neg fuel). By this I take it to mean, relative to these AFR's, that the stock ECU is too lean at lower rpm/lower throttle, and too rich other places, even to hit these apparently rich AFR's. The assumption here is the AFR table associated to a given map is the one used to generate the 001/002 maps on a dyno for best power. And I guess DJ found the FJR mostly likes to run richer than one would expect. [/QUOTE]
