Wideband 02 Sensors

Has anyone had any previous use of an 02 wideband sensor installed on there car? Basically I am looking at the use of a wideband sensor in my quest to learn how to tune cars myself and the use of one of these would be an optimal way of doing so without the need for a workshop/dyno.

Can the O2 sensor be setup to allow the ECU to still recieve information to allow it to still operate in open loop function? Or will it have to be disconnected once monitoring the A/F ratio to the origanal sensor?

I'm basically looking for an O2 sensor which can log A/F depending on RPM rather than just display the reading, so I can then tune the fuel/air maps after logging the data. I am guessing this would be achieveable at a cheaper price by hooking it up to a laptop to log data.

Also I am looking at the option of replacing my ECU soon with an aftermarket one and I believe some support the use of wideband O2 sensors but am unsure which ones do.

I'm relatively new to how wideband O2 sensors work so all information and experiences would be appreciated.

Thanks,

I have a Innovate Motorsports LM-1 installed in my car. It has logging and with the analogue breakout box, it can log 4 channels of data including RPM and whatnot against AFR. It has around 40 minutes worth of logging and you can download the data to a laptop later via RS-232 with the included software. With the inputs, you can even make up a table with TPS VS AFR VS RPM for a grid display. Also the forum support for the LM-1 is second to none. www.innovatemotorsports.com

I had the extra bung installed into my dump pipe so that the stock ECU still uses the original O2 sensor. If you insist in replacing the stock O2 sensor with the wideband, the LM-1 can simulate a narrowband output to keep the stockie ECU happy.

Only a handful of ECUs support wideband input, and I dont think the LM1 can actually interface with any of those.

The LM1 talks very nicely to the Autronic ECU, and enables self tune as well. :(

I bought it from the website. I cant remember off the top of my head what it cost, but 3 day shipping was about 60USD so add that on top of 429USD for the unit + analogue input box and thats how much it was.

I bought a wbo2 sensor from www.zeitronix.com great little unit very accurate, but I didn't buy an LCD output screen so it only works with a lap top.

The zeitronix logger has many input options, like TPS, MAP, RPM, AFR, Exhaust gas temp, and any signal between 0 and 5V.

Would've be way better if I'd shelled out for the LCD screen aswell.

I agree the www.zeitronix.com a/f ratio meter rocks :)

Helped e out something cronic.

      From there, as the manual says....assembly is the reverse of disassembly, no tricks worth mentioning Much better (for me)

      In my case, the standard wheel I had was in good condition but the buttons had more wear, so I swapped them across from the original wheel from the car. The plastic rear cover is held on by 4 tabs, and once the wiring is removed you can get access to 2 screws on each side the hold the buttons in From there I just swapped the wiring over. What was interesting is the standard style wheel is 2.0kg but the carbon fibre one is 50% heavier at 2.9kg. It even has a weight inside the wheel at the top to make up for some sort of imbalance in the design. weird

      Once the airbag is off, to remove the steering wheel.... Undo the 2 plugs into the clock spring, and the horn connector from it's clip. Hit the 19mm nut with a rattle gun (preferably) or if you don't' have one, you probably want an assistant to hold the wheel in place while you use a breaker bar to undo the nut Then, screw the nut back on 3 turns, and pull the wheel sharply towards you. If that doesn't work hit it medium force with a rubber mallet on either side, or possible behind if you can get there. If that all fails (it shouldn't!) you might need a steering wheel puller

      So, to next task....the carbon fibre steering wheel was either an expensive factory option or a chinesium special. Either way, I don't like either the flat bottom or thick ring style, so it had to go So...to remove the steering wheel.... First, disconnect battery negative and stomp on the brake pedal for a few seconds. Then, remove the small circular covers on each side of the wheel's rear surround to uncover the airbag clips. You need to push something like a flat bladed screw driver through, to push the steel clip inwards and pull the side of the airbag forward. Once you've done the easy side, same on the centre console side. You can see the tab you are shooting for circled in red Then, disconnect the horn spade connector and for the yellow airbag plug you need to get something small under the black locking tab to pop it out, then the connector releases......airbag is off
