If I dont have hondata yet.. and I'm OBD1 (w/ single factory O2 sensor), can the Wideband O2 system replace the stock O2? and will the ECU be able to read signal from that Wideband O2? or
Would I have to weld another bung for the Wideband O2 and use it for display purposes only? cant use it for ecu tuning unless you have a standalone, right?>

Added (9/14/02):
Ive been thinking the Hondata Stage 4b is just for boost.
Is it capable of tuning NA? If it is, what problems will I run into?

Also, Is there any feature where I can just record what a Stock ECU does in fueling & timing maps, without interupting it??
I dont feel like starting from scratch & killing a perfectly brand new motor. I heard that the baseline maps that can be given would differ because of the conditions the ecu is subject to.

Thanks

No, wideband o2 sensors are not interchangeable with standard narrowband sensors. The bungs might be the same but the wiring is not. Widebands require special control circuitry to make them work.

 

yes a second bung is needed as the car needs at least 1 o2 sensor

 

but when I have stage 4b, all I would need is the wideband right? since the car would be running off of hondata, and I wouldnt have to weld another O2 bung on exhaust.

 

i have thought about mimicking the narrowband o2 sensor with a simple circuit that takes the wideband voltage as an input. wouldnt be tooooo difficult to make (simple comparator circuit with the - side referencing the stoich voltage) but it woud probly be too much effort if i could get a 2nd o2 bung welded in.

 

Unless you can disable closed loop with Hondata you'll need your narrowband for daily driving. Even if you could disable closed loop it's not worth it. Your mileage will go to **** and you probably won't pass emissions. Even with Hondata you need a narrowband o2 sensor.

 

You can still use it for tuning with the stock ECU, provided you have a piggyback devices to trim fuel

 

stock narrowbands are switching types, wheras the WB (+controller) is essentially a linear output (albeit simulated)

I dont know what the stock ECU software would do with a linear input. I'm betting it would would assume sensor failure and throw the CEL

 

anybody used the "techedge" wideband with a Hondata system?

Recommend any others for a 4b system?

 

you're correct. thats why i was talking about simulating the fast transient response of the narrowband with input from the wideband at stoich. nes pa?
