0-5v output from wideband directly to ecu

[ChIoVnIdCa]

can I run the 0-5 volt output from my wide band to my crome ecu?

You need to mod your ecu for it to read to 5v.

What afr's are you using that the 10-17 aren't enough?

I want to get rid of the oem sensor

[d112crzy]

Ok.

Then tune.

It's a waste to buy a wideband only to use it as a narrow band.

It is tuned... I already have the wideband installed. I have the oem sensor hooked up to the ecu. I have two o2 sensor bungs

[ChIoVnIdCa]

Is it a hardware mod or software

[d112crzy]

It's a hardware mod.

If you want to get rid of the oem sensor then just take it out and plug the hole.

The only thing you have to do is disable the o2 sensor in the program that was used to tune. And if you're tuned, then it should already be disabled. Hopefully anyways.

once I disconnect it the car goes to 17+

[d112crzy]

Then it's not tuned.

[ChIoVnIdCa]

Then it's not tuned.

So bring it back? It should be able to run correctly with no input from o2 sensors

[d112crzy]

If it was tuned, yes.

Who tuned it?

unplugging your o2 sensor should not affect your afr's if it was tuned for full time open loop operation. you need to disable open loop and get your part throttle tuned. If your tuner is using closed loop operation, then I'm gonna guess that they didn't tune part throttle.
