Honda Wideband

[evil_demon_01]

Nearly got the car ready to run. I've ordered Hondata so should receive it next week. My Accord never had an oxy sensor originally (has IMA instead) and I'm putting a wideband on it any way.
My question is: Has anyone used the Honda wideband sensors? And with what results? (5 wire type)
They came in 1995 civic Vtec-E, and also in DC5 Integra (Type R?)
Also how would I go about wiring one in for use with a P28 ecu? Or do you have to have a wideband controller?

bump. . . I am interested as well in this. Thumbs Up. BTW evil demon 01 what is a IMA? Thanks hope some one on the forum helps you. Keep us updated. peace

IMA = Idle Mixture Adjustment screw (above Ecu and only on cars w/o Cata)

the wideband does it's own thing once paired with an engine management system, it doesn't necessarily have to connect straight to the ECU

To run a wideband with a Hondata, you need a controller. Check out the Hondata forums, these questions and more have been asked and answered. It's a great resource for those of us lucky enough to own a Hondata system.

The 5 wire sensors are very expensive. The Volkswagon sensors are used much more because they cost around 30-40 bucks for the sensor. With either sensor unit you will need the controller because Wideband O2's function very differently then a narrowband.

In anycase to interface your wideband to your ECU you will need to use the analog output of your wideband controller and connect that to your ECU's O2 input. Then it is up to your tunning software of choice to interpret the voltages that represent the different afr's. You will probably have to set your tunning software's O2 values to that of the output of you wideband O2 so that they match. Then you're good to go.

The ntk 5 wire wideband o2s are expensive but tend to last longer, the new bosch lsu wideband o2 life span is shorter then the ntk models. You don't want your wideband running your ecu, you just want it for tunning purposes. you basically tap into the output to the display screen wire from the control unit and connect it to the ecu o2 input wire. While datalogging you can run in a trace mode I believe if your using hondata and it indicates how off your fuel is to the the present o2 reading.


edit: Forgot to mention I have the tech edge wideband o2.

so hondata is better than c-rome right ?

That's a matter of opinion. As an OBD-1 option I prefer Crome over Hondata because I beleive it is a better tool. It's also a less expensive option for both the tuner and end user. Having experience tunning and installing both that is my preference.

In my opinion, I haven't delt with crome so I can't say anything about it. As for hondata, I would have to bash it do to the fact that you needed to burn chips have a romulator to tune. The final price tag for all the stuff puts you close to the aem ems. Now I would say hondata has its act together by intrudicing the s300 which allows updating the tune via usb port and having a flash rom chip in the ecu on its own seperate board.

I have the S300, You can save datalogs onto the ECU and download them when your finished (20 mins worth), and everything is in realtime so you can even make adjustments when the car is running.
