What wideband are you guys useing??? what are you guys useing to measure the air/fuel ratio in youre car's???? I.E. dynojet wideband commander, innovate motorsports, ect.... and why???
Im torn between the two listed above.... help me choose the best one for me
thanks

I've been thinking about getting an LC-1 since one of the sponsors (dynotune I think it is) has them on sale with a gauge for $250. It would make a nice "from me to me" gift

I would go with the Innovate LC1 or LM1 and a Dynotune gauge!
A little lengthy but I think it helps explain why Innovates technology is the best on the market. Opinions are great but we chose to carry the Innovate line based on Facts!
The biggest difference is actually the (pat. pend.) measurement principle of the Innovate Wideband. It is different from all other widebands in that it does NOT use the pump current as AFR indication. Instead it uses the sensor to form with the Wideband 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 Innovates measurement principle is not susceptible to that.

I wired it up. I get my bung welded tomorrow for my LC1. I purchased a Aeroforce Intercepter for the other pod opening through another vender. The difference in quality is nite and day. Innovate and Dynotune are both to notch.
