o2 sensor eliminators

o2 sensor eliminators
Living in Wyoming we have no emission tests or standards. On my motorbikes we fit o2 eliminators as bikes are set to run lean up to 5000 rpm or so which makes them run hot and reduced power. The eliminators just feed the signal the ECU needs to run more efficiently.
I have read lots of politics on this but all I need to know is if there is a dongle made or what resistor is required to provide the correct signal.
Thanks

You mean for removing the catalytic convertors? Otherwise, I'm not sure what exactly you're trying to do. Change the A/F mixture? That would take some experimentation and math that I don't believe has been done. Also, slightly lean actually makes more power.
If more power is what you're after, there are better ways to achieve that goal.

o2 sensor elimination
OK well on my motorcycles they have o2 sensors to feed a signal back to the ECU to ensure the correct mixture to meet the emission control standard. This is set weak over the low rev range which causes the engine to run hot. On 2 cyl engines it also makes them run rough. On my old D2 I would like to remove the cats also as this vehicle I use to camp in the mountains. Hot cats are also a big fire risk.
For motor cycles there are many companies that sell dongles to plug on the o2 cable. Then the exhaust port is blanked off. The dongle just feeds a signal back that tells the ECU everything is fine and it can run the correct mixture for best performance and cooler running.
I was just enquiring if I could get a similar plug device for the D2 - they tend to run about $35 a pair.

i prefer the dummy sensors to the spacers. i've had issues with the spacers having no effect despite the sensor being out of the stream.
as for bikes, why don't you just tune them properly? power commanders and adjustable spark advancers are cheap. and newer bikes are OBDII, so all you need is some free software and a $13 usb to obdII converter.

Power commanders are useless without a good dyno tune. Generic base maps do little to nothing.
Ecu Editor works for Suzuki and Yamaha. And you need the extremely expensive Ecu Unleashed shop setup for other bikes, and it also does cars.
"Spark/timing advancers" also know as TRE's, timing retard eliminators, are also usually junk. They perform decent on Kawasakis, but cause gremlins sooner or later on everything. Tricking the ecu into thinking it's in 5th gear all the time is a bad idea for several reasons.
Eliminating the O2's isn't smart without a dyno tune either. Especially since most all FI engines run lean from the factory to pass emmissions.

Just want to remove the Cats as they are a fire risk, and the o2s to stop the lights coming on. My o2 sensors are faulty at present but the truck runs fine, 16MPG US etc Just want to tidy it up.
