well so i got a k20 in my car and runs and driveable... but it runs either too rich or too lean cause it cant read the o2 sensor... well basically i have hondata and new o2sensor for the type s and everything is wired and working from the reverse lights to speedometer and fans and temp... but after starting the car the CEL turns on and throws the code 41 or P0135 and after it runs for a while it will throw occasionally P0134 which is no A/F sensor activity detected.. mch help would greatly be appreciated.. if you need to email me any diagrams it can be sent to zoomxdjspeed@aol.com

when i did my swap, I needed to go with an aftermarked wideband O2 sensor- something to do with the stock rsx O2 sensors Ohms- wouldnt work- don't remember all the tech stuff or details, my swap was done 1-1/2 years ago by Payn Technologies in Detroit, Mi- I do however remember having to get a diff O2 sensor. Look into that

yeah i have a A3 swap and i get the P0134 code too, but i thouhgt it was because i was boosted. guess i need to replace the sensor but acura wants 300 bucks for it!!!

why don't you guys just get an aem uego controller so that you know for sure what your a/f ratio is. Definately a better sensor than oem.

Why not do a K20AR swap :-P It's sooo much more worth it :-D Can't wait until my K20AR is sitting there in my Engine Bay :-D

because to use the hondata logging feature you need the oem type s sensor

That engine is way harder to get and probably more expensive for just 10 more hp

20 hp... and it's more than 20 hp ... remember, shorter gearing, lighter flywheel, lsd.
