Default P28 ECU into '98 Accord EX?

Anyone tried this? Got the jumper harness and plugged it in, starts, but throws check engine light and idles crappy. I'm pretty sure the IAC is different, anyone know for sure? Thanks in advance.

A lof of people have had this problem.

It's due to the IACV. An OBDI IACV has two wires, while ours has three.

Not that I know of other than the swap.

One person had a P28 ECU, and an OBDI IACV. He gave up because he just couldn't fix the CEL, and idling problems.
