    Japanese S14 ECU issues

    Hi guys, I've just imported a S14a which was originally a sr20de but has been swapped to a s14 sr20det. Just wondering if I can directly swap the ECU for a UK or European one or if there are any places I can buy a daughter board for a Jap S14 SR20DET?

    The ECU code is 23710-69Fxx

    that ECU code is for an early s14 with no nats immob, the UK 14a has NATS2 so it wont start + pins are 64 UK ecu V's 74 pin early s14
    23710-69Fxx (JDM), 74Fxx (JDM), 75Fxx (EDM) are all Series 1 S14 SR20DET use Type 3 Nistune board

    I have an S14 Silvia that was imported and the previous owner had a H-Dev daughter board installed. Give them a ring or message on Facebook, they are very helpful and knowledgeable
