Is the defi air fuel gauge as accurate as say, the greddy one?, or is more like the less advanced Autometer?

Thanks

TECHEDGE is what you need since it is a true 5volt wideband while the Greddy ,and similar setups, are 3volt semi-widebands that are horrible for tuning part throttle.

Techedge2.0a uses a Bosch LSU O2 sensor so it's cheaper on the pocket book. I have the 1.5 DIY kit with LD01 display and it only took me about 3 hours to construct both parts.

It's not the guage that is the limiting factor, it's the sensor. The stock sensor (except for certain civic vx model years) isn't accurate enough. There probably are different qualities of gauges between different brands but your oxygen sensor is what is not up to par right now.

Sensor and the heater circuitry. Just adding a 5volt sensor will not help if you do not upgrade the heater/signal output circuitry.

Sorry to bring this back from the dead but I have a question about the Defi A/F D-Gauge.

Would it work accurately with a 0-1v input from a wideband O2 sensor?
I called Autometer and they said theres would not work with my wideband even if it was 0-1v. They said narrow band O2 sensors are actually .5 - 1.0v, however the Defi support page shows the A/F chart starting at 0 and going to 1 volt, giving me the impression that it will work with my setup.

Opinions?
