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 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.

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
