Wideband O2 instead of narrowband sensor.

[prodigymb]

ive had my wideband installed for a few weeks now. here is the situatio....when i got my exhuast done i did not keep the narrowband sensor, now i only have the wideband and i have a CEL that soemthing is wrong with o2 sensor. how do i make the ecu get a reading from my wideband, i know there is a way to do it for a fact. i am pretty sure i read it here or elsewhere but couldnt find anything when i tired to lookback for it.

just get a used stock sensor and drill a hole, weld in a bung and boom, it's all good

the only other thing would be to simulate the "ok" resistance, which i don't know ........if you can do that, then radioshack should have whatever resistors you'll need

This works well http://www.o2sim.com/

Not sure what wideband you have, but i know most of them have an accessory wire that simulates the factory narrowband o2 signal that you would essentially tap into the propped wire on your ecu... my AEM UEGO has a specific i think white or blue wire just for this reason... it will give your ecu the propper reading its looking for therefore eliminating your CEL and allowing the engine to run at its full potential instead of in limp mode....

I took my hondata and turned that option off i turned the o2 off altogether

what management are you using? and what wideband? most have narrowband outs, and you can either turn the o2 heater off in the ecu or put a 10k ohm resistor isntead of the heater to get rid of code 41.

uberdata, and zietronix wideband

it has a wire that you solder to the ecu that simulates narrowband. I think its the purple wire. Read the instructions, it will say on it.

yeah but what about the other wires. cuz there are 4 wires running from a regular narrowband normally?

[v4lu3s]

the stock narrowband has one pair of wires that are the o2 sensor heater, i think those are the black wires. in uberdata you need to disable the o2 sensor heater, that way you can ignore those wires. as has been said you just need to send the signal back into the ecu via the signal wire on the o2 sensor. i wish i had a zeitronix wideband but I am using the Innovate LM-1, and i actually made a plug that is attached to my wideband controller, that I jsut plug intot he stock o2 sensor plug on the engine harness.

i think its the purple wire too. But i spoke to him, my advice is the same as ricky's. Cancelling out the 02 heater sends it into open loop which is fine...but his car is far from tuned yet.

[v4lu3s]

so uberdata doesnt allow you to turn the o2 sensor heater off independantly of anything else? thats pretty crappy! I know Crome and Hondata allow you to do that.

[MRX]

the older versions had the 02 heater disable, but the newer ones don't. Instead they made a tps/load dependant closed loop cut off

ill just get a narrowband put in tommorow !
