setup is

97 240sx ka24deaem ems 30-16113.5bar mapams fuel kitt3/t04excessive intake manifold w/ q45 tb

the ems can see the map sensor, and all the other sensors, and it was working fine while n/a, but now we have installed the turbo kit(custom) the ems does not want to read the distributor, it can't even get rpm signal.

we tried swapping distributors, changing the resistor/condenser and that still did not help, i've checked the engine harness and don't seem to be missing any grounds or anything like that.

we also get ~12v @ the coil.

also were not getting spark or fuel due to the ems not being able to read the distributor the wiring seems to be fine going to it though.

also if anybody has a cal for this setup, could you email it or post it plz.

Has to be wiring somewhere if it was working but all of the sudden isn't. Most likely pinched or broke a wire somewhere during the turbo install.

it could be wiring, it may be wiring to the coil, cause we changed the coil wire from coil 1 in the ems, to coil 2, and it started reading for a bit but then it stopped doin so(meaning we could have fried that wire due to a short somewhere)
