crxtasy is right, the shit that the kit come with is crap, but it's most likely not your map, but rather you tps, the t tap that is included is more likely to cut the tps wire in 2 rather than tap into it, the best bet is to take that t tap off and soder is in place and shrink tube it, i had the same problem back on my dx engine, and that's all it took to fix it...
oh and about the seat, 2dr teg rears fit civic hatchback, and 4dr teg rear fit coupe, as far as 4dr civic's go who knows
