Engine code#67 low cat. effeciency?
I have a 98 Jdm b16b in a 2000 Civic, I'mRuning a p61 ecu ( Obd1 Gsr ) After dyno tuning my car and getting the fuel ratios and timing map just right, I'm still getting engine code 67 ( low cat. effeciency) Why????
I'm runing a Holley 255 fuel pump, AEM fuel Rail, 450cc injectors and my pressure regulator is set at 39 when in normal operation temp! I Have a test pipe and my cam breather line is not connected to my cold aire intake!
Need help or need to know where to look???
Thanks Pat

i had this code once on my stock ex motor. What ecu are you running? i got a high flow cat and had a 02 bung made for it. that fixed it, good luck.
