Default electronic secondary o2 simulator

I've never gotten any of the manual/mechanical 'anti-fouler' style o2 simulators to work consistently, and am just looking to wire up the electrics to trick out my MY '05.

Anyone know where I can get one (they're oddly hard to find)?


Also looking for something similar to cancel my air-pump delete check engine light. Any help?

i just tried the J hook style defouler and it didnt even last 20 miles. Bump this, i hate seeing that CEL on. i guess i can always go back to a stock cat.

You can use a aem or haltech ecu and those will turn the cel for the o2 and air pump. This is suppose to work for the air pump. No first hand experience though http://www.izzeracing.com/Site/Honda...Simulator.html

Thanks for the info on the air pump simulator. I'll check into that. I'm not looking to invest in a full on EMS just to deal with a couple of CELs though

Air pump simulator works great.. if you remove the air pump.

You can try go to an autoparts store and buy a spark plug anti-fouler, drill that out and just take the sensor further out of the stream. I used that in addition to a berk test pipe w/ built in O2 fix and never had a CEL again. I would keep getting a CEL with just the berk pipe.

AP2 is a hit or miss. i have the berk HFC with the built in o2 fix and the vibrant J hook defouler. still CEL. i am gonna try buying one more spark plug defouler and put some steel wool in it.

The mechanical / anti fouler method is unreliable; quite hit or miss for all models. I also clearly stated that I will be playing around with the exhaust over time including possibly cutting it quite short after the header. I want a simulator, not a mechanical method to fool the O2 sensor.

then you need a full ECU or K pro to shut off the secondary. people have tried putting a 1 ohm resistor inline and that doesnt work either.

An electrical secondary O2 "simulator" is in the works; preliminary testing indicates that it won't be trivial to bypass. This solution would completely remove the secondary O2 sensor (i.e. you don't need a working O2 sensor).

A somewhat different topic but I've already developed and successfully tested an EVAP simulator for the S2000 (and it should work on many other Honda & Acura's). The EVAP monitoring system is very clever and difficult to bypass.

Caleb, please put me on your list for your simulators and let me know when you get them done (stevevetter@gmail.com). Also email me any web site you have or whatever for what you've done. I may be in the market for your EVAP simulator.

It's actually funny you bring that up as I just put an F22 in my MY 2000 with the MY 2000 CPU (will put in the 2005 ECM, but the seller forgot to send me the key at first), and I of course unhooked all the EVAP stuff. I throw codes for no air pump (plan on getting the simulator for that) but I've not thrown any other EVAP/emmissions codes.
