Ok, I have a 99 civic dx with 99 b18b Greddy turbo with intercooler. Everything is legal except the ECU. I'm currently running an OBD1 computer. I know for sure that I won't pass with this ECU. I do have a 99 SI ECU. I was thinking that I could swap the ECUs and hide the "Check Engine Light" somehow. Do you think I can pass if I do it this way? That's what I am planning to do. Also, I'd let the car run for a long time to get the catalytic converter nice and hot and make sure it's working to its max. Anymore ideas? I live in Northern Cali. Anyone know any shops that can maybe hook it up? Please help. Thanks.
