ok we swaped a b18c1(US) motor and a EG and after starting it up i got a CEL code 14 and 41, 14 being IAC (EACV) - idle air control valve and 41 being Primary oxygen sensor heater. Im wondering if i need to re-pin anything? We also put a Blox intank mani. and s2s2 cams, s2 springs and ti retainers, JDM header. I also have a ECU that is socked with a zif chip, but its not tund yet. On the stock ECU (gsr) at about 4500rpms the motor falls flat on its face i cant figure if it is in limp or not. we have swaped my friends chiped wanna be jun spec ecu in and the motor runs fine. Any help would be great

thanks john
