I just installed my test pip today....drove it for like 50 miles and then the check engine light comes on....anyone knows why?...is it due to the O2 sensor?

 

yes
OBD2 sensors

 

so what should i do to sovle the problems?...will it come back on after i reset the ecu?

 

yes it will

 

so the engine check like will always be on?....but that's not a problem right?

 

so it doesnt a bung for the 2nd O2 sensor?

 

why don't you jump the jumper and find out what code it is then diagnose your problem.. your iacv could be throwing a light or vtec isn't hooked up and it's throwing a light (not saying that's the problem) but just don't jump to conclusions thinking it's the o2 sensors...

 

you can put the O2 sensor in the cabin, so you wont throw the light, when that light goes on you lose 2 deg timing, thats what i heard from acura

 

This is what you can do but you may have to do this every 3 months.
Take tin foil and wrap your o2 sensor then wrap it with metal wire.
Place the tin foil back in the test pipe and reset your ecu. You light will not come back until your tin foil burns away.

 

thx guys

 

Get a high flow cat.

 

Ive done that;kind of a pain in the ***;having to keep taking it out and replacing the foil,.on a early post 1 guy suggested plugging the second 02 sensor in the bung in the header,and wrapping the first o2 sensor out of the way,im thinking of trying this, has any body had any luck,....

 

what will happen if i jsut let the light stays on?

 

would you run into limp mode?

 

if you put some cat material aroun the O2 sensor it will work without throwing a code. but that means that you have to hollow out your cat to get some material. or you can do a P28 ECU. thats what i did. its up to you
