Default EX motor into LX body- What should i expect?

Waiting for a battery right now to test the completed the swap and now i'm wondering if there are any mod's to make it work or is it interchangeable? Would i need to swap the LX ECU for the EX?

Pretty straight forward... pull and drop. And yes, you will have to swap ecu's... the EX is the VTec model (assuming this is a 94-97).

Even with a 4th gen he would need the EX ECU due to the secondaries, other then that he's fine.

These are 90ex into a 91lx using the lx wire harness. Dropped a fresh battery in, cranked it, and it rev'd high, like 3.5k rpm high. Swapped the ECU's. Checked the vacuum, throttle cable, and idle adjustment and still rev'g high. Unplugged the IAC and it came down to 1rpm surging of course. I swapped the IAC and STILL rev's up like a cranky bitch!

I've spoken w couple Honda techs and none could give me definitive suggestions. I notice the fans are not working too. SRCRX says the diz is wired different. LIke how? Could it be the wire harness?
