I seem to remember you need to retain the S13 ECU, but I may be wrong. You had a DE engine originally, I'm assuming? If so, engine is pratically the same(did you just use the S14 head/block, kept original sensors,etc?), the m/t is the same, so the difference is in the ECU/gauge cluster. My guess is the S14 ECU isn't compat. w/the S13 odom/speedo. Do you have any friends w/an S13,M/T? Borrow their ECU.

Any backup on this? I'm only speaking from speculation.
