Oh and as far as O2 simulators , what exactly would you need? All an O2 sensor does is give a voltage output corresponding to the sensor input. I guess you might be able to just hookup some sort of voltage source to it???? But thats only if it would be considered ok by the ECU to see a constant value from the O2 sensor, the case might be that it needs or expects to see certain variations , like at WOT or maybe while warming up, but i dunno.
The ecu expects to see above .6v fully warm engine with throttle plate fully open. With throttle plate closed it expects to see below .4v. This info is for the secondary O2.I'm not sure if it is the same for the primary O2. The real question is how much fuel mixture/timing control is controlled by what the primary and secondary O2 sensors see and signal to the ecu, can we essentially tune our engines by manipulating the signal to the primary and or secondary O2 sensors with someting as simple as wideband with variable analog outputs?Here is what I have and, I am really impressed wth the quality and flexibility so far.

how does the test pipe change the sound output? I remember when I put a test pipe on my civic, it totally fawked up the sound. It was nasty, but fast :-)

any one running a test pipe with just the stock exhaust?
