So I finally completed my ls vtec swap in my crx. Wired up the obd1 distributor, removed the resistor box, wired the obd1 rc 310 injectors, wired the jumper harness, and plugged in the ecu and have it running good. How ever when I go it red lines at 4k. My rev limiter is set at 9k. I tested the ecu in a 93 hatch and it works fine. Does anyone know what could cause this problem. Please let me know. Thanks.
