Hondata

if the guy I bought it from was wrong and the ecu is for a 02-04 is there a way for me to find out cause I would also like to get it upgraded this ecu to v3 but if this ecu is already modified for 05-06 and not right for my car there is no point of sending this ecu to you and wasting my money

The guy I bought it from said it was in his 06 rsx and it came with a hondata adapter harness

I bought the wrong kpro not knowing there is a difference it is for a 04-06 serial number 2689 I have been using it and it works fine in my pretty much stock 02 rsx. I just took it out cause I read you are not suppose to use it. I just want to know why not it seemed to work fine every thing seemed ...
