This might sound dumb, but how do you tell if you have a rechipped p28 ecu?

I just bought a p28 ecu (thought it was stock), plugged it in my civic (gsr motor) and it works close to the same as my chipped ecu. I have no check engine lights. It runs alittle leaner. I have not checked too see what red line is.

 

open the ecu, if there's a a 28 pin chip and socket at the lower right corner then your p28 is chipped

 

Thanks...it's stock. I was just suprised how well it ran with it. I figured it out when I hit the fuel cut off (7500).

 

maybe its not that the stock p28 is sooo great maybe your chip just sucks. sorry.

I bought the stock p28 for a Hondata system. I just plugged it in to make sure it worked. I like my chipped one (kenji chipped), just looking to try something different.
