I was wondering if there is a computer fooler module or something you have to use if you are using a test pipe. I know if you do nothing the ecu throws a code. I am not sure though if the a/f ratios will be screwed up or if the car will suffer any tipe of damage by using a test pipe. Could someone address those two subject matters? Thanks!

The only code(s) thrown from a test pipe will be emissions related. They are simply there to inform you of a failure in your emissions system. The ECU does not use the readings from the Secondary O2 for anything to do with it's fuel delivery. If you are comfortable with a CEL being on you can drive the car without a Secondary O2 properly hooked up. The are some O2 simulators that people on the board have installed but I do not beleive that there is one yet that has worked on each S2000 it was tried on. Seems to be hit or miss.

would it really be an issue on an N/A car to keep the cat?

REMOVE the ecu reset fuse
no codes
no problems
no back pressure
save 15lb of weight
consider Mugen ecu just emliminates the sensor...what is the big deal??
remove the fuse
you will be happy
I sure as hell am
Damn Brian...you want me to spend 10 a quart on Ester oil from switzerland...and tell me trust you

yes those are only down sides...also no beep beep when key is in ignition
I have had NO irratic idel
great mod a few hp from a dyno and lurker said so
plus save at least 10 pounds
if you live in a smog check place
plug ecu back in, put cat back on, and run about a tank full of gass..so computer remlearns things for smog check
i think its worth it
