I will be installing my HKS exhaust and IHI type 1 test pipe this weekend. How would I go about getting the CEL to turn off?

 

pull the battery cable off before you do it..shouldnt have any problems if not you gotta reset the ecu...if you tamper with any o2 sensors...yur gonna have cel

 

It's not that simple...i wish it was. S2000s are pains in the ass

 

what code, just replacing the exhaust shouldnt throw a code as long as theres nothing disconnected to open the loop.....

 

you know what, i just figured out you were talking abot your s2k, and not your crx, but i would still think it wouldnt matter.......

 

cant you just pull the hazard fuse out on those to reset the ECU? that works on most hondas!

 

Well he said hes using a test pipe...that means that the 2nd O2 sensor(I'm guessing s2k's have them). Is going to throw a code because the lack of the catalytic converter and cause your a/f to lean out. You'll need an O2 sensor simulator they aren't really expensive. It basically tricks your 2nd O2 sensor into thinking that your a/f is fine. I'm not to familiar with s2k's but that is the basic stuff

 

find out what signal the 2nd o2 sensor sends the ecu when functioning normally. get the correct ohm resistor and wire it in there. biggity bang.

you could always try leaving the 2nd o2 sensor on the exhaut so it heats up just not inside.

or...I have an obdII interfaced program on my palm pilot that does some neat tricks...one of which I know will clear CELs on dsms. might work for your car too if its obdII.

there i hope that was more helpful than "reset the ecu"
oh brother

 

www.pocketlogger.com see if it works for your car.. if it does, it's a great tool, i reccomend it...

as for other ways:

1) take out the light bulb behind it
2) pretend it's normal
3) put some black electrical tape over the light and forget about it
4) ignore it

 

lol, i've done all of the above...dsm's...
