I'm not advertising anything for profit, but I have been searching for an inexpensive wideband sensor and controller for a while.

On Ebay the things seem to sell for $200 used. Even the DIY kits can be expensive, and are generally huge. I have seen another one offered on this site for $320.

But after browsing many sites, I found this one that sells a very small, compact controller for a steal: $105. With sensor is $275.

TwinTec.com

The controller is the smallest I have seen, and I like that it has a calibration potentiometer. This display is going to replace the stupid LCD clock in my Rio.

Now I just need to find a cheap L1H1 or L2H2 sensor. I think I can get a used one since the controller is adjustable! (Free air calibration)

A question on sensors:

The LAF sensor that comes in the Honda Insight is an L2H2, right?

buckfittyone

thats a hot deal.does that use the sensor fron the civic cx?

beepy

CX? I don't know. I know the L1H1 was used on the '93-'95 VX, or 1.5 VTEC. I also read on the website that the L2H2 (same sensor, different harness) is used on the Insight, and I want to confirm this because I may be able to get a brand new one for a song if it is true.

I just couldn't pass up a $105 wideband controller. **** DIY.

yah im gettin down is

interesting. I have an L1H1 right here along with a displayless diywb controller i built. Maybe this would be a better solution than trying to figure out the diywb display. it looks like a nightmare to me...

make sure you post up your impressions once you try it out. comes with 3day shipping too I have been using a PLX m300 lately and it's exactly what I would want for datalogging other cars but this one looks like it would be good to keep permanatly installed.

tight yo! What exactly is the wide band o2 for?

drvfast

To monitor yor air fuel

XDEep

call me when they support the $50 bosch sensor..

beepy

They also have another unit on the site that supports the LSM4 and datalogs. But it is much more expensive.

does this wideband use the same harness as the ones found in hondas? if so i might have to jump on this and go to a u wrench it place and snag one

tyrone27

can't you wire it to a bosch wide band sensor. I mean a wide band sensor is a wide band sensor. so it shouldn't give off bad reading.

beepy

I have asked that question before and have never gotten a good answer. Honestly I don't know if an L1H1 and a cheap Bosch have the same "lambda graph".

If they did, I would figure there would be adapters on the market, but I have never seen one.

XDEep

they are not the same. they usually require separate controllers. i forget which one, if any, support both in the same unit.

The stock O2 sensor is like a light switch that has a trip point of 14.7:1 a/f ratio - below this value it puts out ~.1v and above this value it puts out ~.9v. Completey useless other than to let you know when you're below 14.7:1 and thats not exactly a ratio you wanna be at when your boosting.

A wideband produces a discrete voltage value depending on the a/f ratio.

ya it supports the bosch and its $425. definitely not worth that. the plx m500 for $490 is wayyy better.

I get the feeling the L1H1 sensor unit is being discontinued... that's why the LSU4-based unit, with the sensor that costs $125 less, is still commanding a premium.

Might be a good buy for someone wanting a display, or who has a method of taking WB controller output and datalogging it seperately as needed.

beepy

The L1H1 is actually sold as a Bosch branded part now. I doubt it will be discontinued because honda still uses it (the L2H2) in the Insight. (I confirmed this)

I still think it is a great deal. If I look hard enough I am sure I can get a sensor for cheap.

i have a freind who bought the twin tec unit,ill let you know how well it works out,he paid $250 for it shipped off ebay from twin tec.i persoanlly bought a techedge diy kit,took a while to get it up and going.i had a palm logger and all the trimings.had about $450 invested into it with logger,display and sensor.worked great.

buckfittyone

i checked with autozone and they sell the compatible bosch unit for $150 but im sure i can still find a used one for a better deal from a junkyard.are there any other vehicles besides the 93-95 vx and the insight that uses the l1h1 or l2h2 sensor? i heard the civic hx uses the sensor also but i could be wrong, can anyone clear this up?

XDEep

ya hx uses it also. good luck finding one..
