Ecu - Honda Prelude Forum

Ezomatsu · 12-05-2009, 12:55 AM

Hi
I have an P13 3GA ecu coming from a european prelude (h22a4) and a P13 3NO ecu coming from a japansese prelude (H22A).
I know that there is a difference in the camshafts and in the pistons between a H22A and a H22A4, but I like to know if there is also a difference between the ecu's from these cars...?
The one has a knock sensor, and the other doesnt, I know, but something more?

regards,
K

This is an excellent question. I don't know all the regional differences, but I would say the fuel and ignition maps are going to be slightly different. Potentially the emissions controls also, but I don't know what kind of emissions controls EU uses.

This is probably the best answer you will get.
