Map Sensor Wiring?
Is the MAP sensor wiring from a stock auto ej1 the same on a '99 B18C1? Swapped my motor and in limp mode could map sensor wiring cause this?

since you didn't list what wire colors you have or which harnes you used I'll give you general directions.
D21(ECU) - MAP signal - 3(MAP)
D19(ECU) - MAP power - 1(MAP)
D17(ECU) - MAP ground - 2(MAP)
and no that's not the same way your original sensor was wired. (3&2 switched)

strange... those wire colors don't look like any that the manuals show.
EG:
1(MAP) - yellow/green (or yellow/red) - power(5V)
2(MAP) - green/blue (or green/white) - signal
3(MAP) - white - ground
GSR:
1(MAP) - yellow/red - power(5V)
2(MAP) - red/green - signal
3(MAP) - green/white - ground
it doesn't really matter though. As long as the connections are to the right points on the ECU the colors of the wire mean nothing.
take a multi-meter and ohm out the connections to the ECU.
out of curiousity which CEL are you getting?
3 is very different than 5
