O2 Sensor Replacement / Bosch 5 Wire?
1 Attachment(s)
hello,
Could i just replaced my oem o2 sensor with a wideband sensor like bosch 5 WIRE ? here is a pic Thanks |
Not if you are using the stock ECU.
|
i' ve just bought an apexi power FC ,
|
still no you would need the datalogit.

So - with a PFC you could run with no sensor at all. |
I WOULD JUST A WIDEBAND SENSOR TO MEASURE AFR with my power fc,
no other issue than dataloggit? |
Not gonna work. The sensor is only part of a wideband - you need the controller box and the whole 9 yards. The PowerFC itself can't do anything with a wideband sensor - the Datalogit is necessary if you want to log what the wideband is doing, and even then you need a full wideband kit.
In other words, it won't work. Dale |
Like moconnor and dale say you will still need something to power the sensor, i know iv tryed haha.
|
with apexi power fc
If i buy "innovate Motorsports LC-1 Wideband O2 Lambda Sensor Kit " with datalogit , i could work for o2 oem replacement , PLX Devices M-300 Wide Band Oxygen Sensor Kit could work too, without datalogit? |
Wideband sensors do not have the same output as the stock O2 narrowband sensor. If you want to run without the stock O2 sensor you need one of two things:
. a wideband controller than also outputs a narrowband signal that can be fed to the PFC. Very few wideband controllers do this. I don't think the two you mentioned do, but I could be wrong. or . a Datalogit to tell the PFC to ignore the stock O2 sensor. You will still need a wideband controller to drive the sensor. If you want to log, you need a Datalogit. |
Actually, any of the currently available wideband setups can output a simulated narrowband signal. That you need it with the PFC anyway, as you can tune cruise and light vacuum areas and turn off the o2 feedback.

Thanks for these explanation

u need a microcontroller that reads the sensor voltage and translate into something else.
like AFR 9 to 14 = 1 to 5 V etc... basically just the sensor itself doesn't work. unless u know how to decipher the 5 cable into some readable voltage and calibrate it along with a home made voltmeter <=> AFR value. safe yourself big troubles... get innovate LM1 or LC1 with digital meter. |

TBH i would just ditch the stock 02 and run with nothing.
