i recently bought apexi pen type turbo timer.. how to install this timer?? i used l2s engine but i dunno how to connet the 02 sensor and air/fuel ratio.. anyone.. plzzzz....:hmmmm:
Planning install Apexi Power FC on my Altezza 6mt.
Is it worth buying? Since im stock n/a engine, with catback system only.
Will there any difference on the performance?
