I am running a revhard kit with a hondata s200b, after i did my custom exhasut piping, my cel came on and threw code 41, which is a heated o2 sensor.. My question is, is my car running in "limp" mode? I cant really tell with the boost...

 

if it is in limp mode you can not rev above 4.5k

 

I can rev past 4.5k, i havent been driving hard though, i have only been bringin up to 6k at most and i only did that once..This is the second time i threw a codde 41 and the first time i threw it b4 i had turbo, i still could rev it past 4.5k..

O2 sensor cels won't put you into limp mode. I know this for a fact.

 

take it to your tuner and have the o2 disabled and see if it comes on. i have my o2 disabled i mean there usless. they just plug the holes

 

What do you mean they just plug the holes?

 

hondata you can turn the o2's of if want unplug them and take them out. i took the front o2 out and now using fjo wideband
