Default Idle issue on B18c1 swap with Si(p2t) ecu...

Alright guys. Just did a b18c1 swap in a ek using an 99-00 Si ecu & 99-00 Si harness. The problem is that when I first start it. It idles fine but the more I drive it. Seems like the idle gets worse and worse, and it starts to miss at idle, and idle really low. I reaplaced the plugs & wires. Checked the dist & rotor. All look good. I just dont know what to think. The more I drive it. It just seems to barely want to idle and seems like its missing. Any ideas?

Only thing I could think is that the Si(p2t) ecu doesnt like the b18c. Think a P73 ecu would make it want to idle better?

you need the gsr ecu, different fuel maps/vtec point and the seconday butterfly in the IM.

Yeah, its called fucked up fuel maps and ignition tables. Just get the right ECU and go from there.
