Please share your opinions. I have a Techedge but am in the market for another WB. Specifically, one the that can display in a meter (2" dia?) that I can mount in piller pod housing. Data logging would be good too.

 

well, if you saw that I just posted on buying one - my searching has shown that pretty much all of the mainstream options have outputs for a guage. I picked the LC-1 (Innovate) because I can run an analogue gauge if I want to - but more importantly I can set it up to emmulate the narrow-band readings of the stock ECM (you can program it to do both functions simultaneously since it has two outputs). It is also the cheapest WB out there (sensor included). It seems that most here in scan/tune have had positive experiences with the LC-1 unit, so I went ahead and took the plunge with that unit off an ebay store for $190 shipped (NIB).

There are more expensive units out there - but for my purposes of verifying AFR while driving... not sure I need anything more than what the LC1 provides. FWIW - I plan on using the WB in narrow-band emulation mode, and datalogging with Datamaster to verify AFRs under various conditions. I may even get a gauge in the future if funds permit...

 

I have been using the Zeitronix ZT-2. It works very well. It has a flat display that can be used to show RPM/MAPv/AFR simultaneously. It can also double as a NB O2 wired into your ECM. I've used the optional Pocketlogger software that allows me to use a Palm IIIc for datalogging instad of a laptop. Its a pretty straightfoward application.

I feel the Innovate is the best on the market But let me tell you why not just saying it.

The biggest difference is actually the (pat. pend.) measurement principle of the LM-1/LC-1. Different from all other widebands it does NOT use the pump current as AFR indication. Instead it uses the sensor to form with the LM-1/LC-1 circuit what's called a delta-sigma analog to digital converter. The difference is that the analog signal in this case is not a voltage or current, but directly the exhaust gas composition. This allows it to:

A: react extremely fast with no settling or overswing
B: be independent of electronic parts tolerances and drifts
C: compensate for sensor drift due to aging every time you do a free air calibration.
D: calibrate for the actual sensor characteristic independent of the factory calibration resistor, which is only correct when the sensor is new.
E: is much less susceptible to exhaust back pressure.

Another advantage of that measurement principle is automatic compensation for 'rich gas loading'. This is an effect most WB manufacturers do not compensate for or even know of. When a WB sensor is operating in a rich gas for a prolonged time (minutes), it's cells 'load up' and slowly drift, requiring more and more pump current. This will indicate richer and richer than it actually is. If the ECU is WB controlled in closed loop, the engine would actually run leaner and leaner to compensate.
The LM-1's/LC-1's measurement principle is not susceptible to that.
