wideband lambda sensor options
wideband lambda sensor options
(OP)
I've always used a bosch lsu 4.9 sensor but just realized that I'm limited to a maximum rich mixture reading of 0.65
This is for a racing application and I don't plan to tune this rich but if for some unknown reason my fuel does run richer than this setting I'll have no idea how rich the mixture may have gotten.
I've looked high and low and haven't been able to find a sensor that will indicate a mixture lower than 0.65
Can anyone point me in the right direction? Is it possible to tweek the resistance in the sensor to capture a richer mixer? I don't need to be any where near a value above 1.0 so I don't mind loosing capabilites on the lean side.

I guess I was just a little surprised that the sensors can't produce a reading below that point. One answer I got was since their meant for OE apps that they never needd to be designed for a lower reading.

In which case you are controlling lambda for temp control which then becomes your feedback loop (and the lambda value, per se, become irrelevant. All of which has to be taken with a pretty hefty boundary condition of rich misfire.
