i wanted to know if a wideband would plug and play for a stock honda ecu i was reading something about narrow band and no heater signal so i would get a cel i want to know would it work on a stock ecu and on my setup i have a crx converted to obd1 ls swap.
also i read about putting a resistor on the heather for no cel. just wanted to throw that out there.
thanks for all the help in advance and lmk.

 

no

 

Can you explain why not?

 

Why do you need it?

 

They read at different voltages, and just how do you plan to connect it to the stock ecu?

 

lol thats the part i was thinking of running a spade connector to the pin on the engine harness to run to the ecu, also i need it cuz my car is burning some serious gas like v8 status 10mpg city and 14 mpg highway

 

And the wideband is supposed to do what to fix it? Nothing. You have other problems.

 

lol doesn't the o2 sensor contorl air/fuel mixture also heard a bad map sensor can cause low mpg but im not getting any CEL'S.

 

Does your car come STOCK with a wideband?

 

the ecu can only adjust parameters so much based on values it gets from sensors. if you're running so rich it's blowing black smoke, you have much bigger issues.

 

no, but if im not mistaken WB O2 sensors are 4 pin to the gauge cant i just plug into the engine harness instead?

i just found this thread but idk because u seem pretty sure that the wideband would not working

also no smoke thats the weird part.

 

Hm. Notice how no one in that thread knows for sure? If you want to be the guinea pig, be my guest.

No plug and play.
Buy a factory o2 sensor.
The wideband o2 can be program to simulate the stock o2 but the factory ecu needs to be reprogram to read this.

So then it comes back to why not just replace the factory o2?
And if your losing a ton of mpg it could be other stuff also.
