I'm looking at getting one but would like to hear from others that have used it.

Thanks,

You can get an FJO WITH data-logging capabilities (not just a port) for quite a bit less than that.

go here: www.widebando2.com

I have personally used this O2, it does also have an output like the FJO for dataloging, and I have seen it used in RX7.COM's cars, as well as PFS' cars as a tuning device, you can also see it here on the bottom of this links page:

rynberg- I was aware of the fjo kit but the Bailey uses a better/more accurate sensor than the fjo.

rx794- Wow, rx7.com sells it for quite a bit more than this other place. Good to hear that this is the meter they use to tune cars with.

rynberg

Ummm....Please provide proof of that statement. I believe the FJO uses either a NTK or Bosch wideband o2 sensor. Lots of people use these and have found them to be within 0.1 A/F ratio of the $5000 systems at the dyno.

Please provide your evidence that the Bailey kit uses a more accurate sensor -- especially since ALL the "budget" widebands tend to use the same damn sensor.

The fjo uses a wide band NTK L1H1 sensor that is calibrated more for lean burn. The Bailey uses a wide band Bosch LSM-11 UEGO sensor that a true wide band sensor, higher quality, more accurate for a broad AFR range. Also can be used for other fuels. There is also a NTK UEGO sensor that goes for ~ $1000 USD (way out of my range), not the same as the fjo sensor. In fact a lot of dynos use this bailey wide band meter and no, it doesn't cost $5000.

Actually, setzep, you're off a bit. The LSM11 is a 4-wire Wide Range oxygen sensor, not a wide-band. The L1H1 is a 5-wire UEGO sensor. Neither are wide bands, which commonly employ ion pumps and remote heaters.

In the end, for the hobbyist, the LSM11 and L1H1 are both equally capable sensors. If you're doing academic research, neither are acceptable, but you're also not considering $1000 systems designed for cars.

I stand corrected.
Sorry for the confusion.

ok now a new topic.
fjo vs Bailey
Has anyone run these two meters side by side? If so do you get the same results?
