i'm wondering if i could swap the computer or o2 sensor from a higher output vehicle (bigger than a 4 cyl) to my 240 so that i can performance tune the stock ka24de engine, but still have the comp think that the emissions output is in or under normal output range specifications for the stock engine (not the one the o2 or computer is from)?
i don't really know if this is possible without completely ****ing the car's computer over by burning it up or possibly just having it not work anymore.
but if anyone's tried this i'd really like to know if it's possible
it would be a fun improvement on my car
but i have my doubts
