...check out the LM-101...anyone using a wide-band meter?

..check out the LM 101 tuning videos at the URL below very informative and accurate.

...last year the only option were $1500-2000 wide-band meters

this should be an excellent tool for those that are altering fuel and maps

Nice piece.....

PanTTher

I have something similar to that.

This looks verry good, for a serious tunner that wants to try diff computer set ups etc. Or for a group of people that are always tunning. Ill stick with the halmeter it still uses the lambda sensor.

Jeez....You can build one for $15, or put in this analog/digital for $20....

.....for only $100 more...as well as significant logging capabilities via computer with included logging software...futher you can permanently replace the TTs narrowband sensor with the bosch wide band sensor by connecting the analog out to the o2 connector...this provides two benefits:

more accurate lamba to ecu...and accurate logging to computer, as well as a standard analog meter near dash. Further, 4 additional ports are provided for other sensors. unit has flash and can store 90mins of logs without laptop present.

this may be one of the best tuning tools to verify mods related to fueling and TPS/intake.

The sensor is a bosch lambda sensor. The accuracy of the gauge is great. When you made yours what sensor did you use?

No need for an additional 02 sensor..

and I can attest to that.

I wouldn't use a wide band for other than tuning the car (as in connect it's output to the ecu) and here is why:

It's hugely impractical to wait for the sensor to heat up before you turn the engine on. Warm up takes about 30 seconds, maybe more (can't remember the exact time). Of course after a while you will get complacent and you will start the engine before the sensor fully warms up and in doing that, the sensor will foul up slowly, then stop being accurate and eventually stop working. I have been warned that these sensors foul up very quickly and they are expensive to replace. The sensor alone can cost well over $200 depending which brand it is.

I don't think you will see a noticeable benefit by wiring in the wide band into the ecu because you don't know what the internal algorithm that analyzes the standard O2 is designed to do. It likely has some elaborate short term and long term averaging built in (depending on the conditions) that gets the lambda nuts on. Once you tune the engine and it's running fine there is no need to continue using this tool imo.

But it's a great tuning tool regardless.
