Hi I just installed kpro on my 06 RSX type s and the car has a rough idle and the car runs like crap.
Mods: Buddy club race header, Greddy SP elite exhaust, and Mugen intake box.

ECU is off a 03 type s, with a 03 type S primary O2.

Need some help.

Thank you in advance.

Which map did u load? Who tuned it, more info please.

Sorry, I just used the stock ecu tune so that I can drive my car to get tune. No one tuned it yet. Also forgot to mention that I was getting a CEL code P1166. Could it be a bad primary O2?

Thanks for the help

Indeed malfunctioning primary oxygen sensor.
Did u replace it? Or is it still OEM?
Did u place the kpro yourself in your ecu or did u buy it like that?

That your car runs like crap is due to the bad A/F ratio because of the primary oxygen sensor which is broken, replace it with a OEM.
I've had a similar problem some time ago.

That's what I get for getting a used OEM one from the forums...
I bought it installed. Cool now off to spend $300 at the dealer for a new O2 :)

Thanks for the help.

Perhaps its good to check the cabling first.
