Does anyone have any info or experience w/ this? How accurate is it? Is it more like wideband or Autometer crap?

 

it ain't the gauge, it's the sensor. unless the GReddy unit comes with a new O2 sensor, it won't be any better or worse than anything else. i have the autometer and a datalogger, and they both show the exact same thing. O2 "gauge" is a very simple piece.

 

The GReddy comes with a new O2 sensor and it is much more accurate than the stock O2 sensor (I have seen it in action). The GReddy also reads out in actual A/F ratio as opposed to lean/stoich/rich. However, be warned that it is in no way as accurate as a wide band O2 because O2 output is affected by exhaust temperature, and the GReddy cannot compensate for that (non wide-band)

I'm in the process of installing mine as the main sensor for my Hondata 4b. I'm having some issues right now and Greddy USA SUCKS!! The Greddy and Tomei gauges both come with their own sensor and amplifier/heater. They are also considered to be semi-wideband. Widebands have a short lifespan when used for more than testing/setup.

 

I solved one of my problems so all I have to do is connect the OEM harness to the gauge tomorrow. I got some good open loop runs tonight and I also got to do the required burn-in runs for the Greddy sensor. I'll keep you guys updated on the performance of this gauge and my setup!!

 

has anyone actually used it? or compared it to wideband?
