Predator Data logging

Will the predator for the C6 log AFR? Is it useful enough to show me if I'm running rich or lean so I can adjust for that condition?

Yes it will but I wouldnt use it to try and tune it to the edge based off the reading as it is not as accurate as a wideband.

Just to clarify, the accuracy issue is not the fault of the Predator, it is because there is no wideband O2 sensor on the car. For AFR, the Predator is essentially just a voltmeter and should be able to record the output of a wideband O2 just fine.

I've spoken with a Predator tune programmer, and I was told that the AFR value is pretty damn close (spot on) for N/A cars. The AFR value is gotten from a PID in the ECM (lambda value) - that value is then converted into the actual AFR value.

I also chatted with a guy here on these forums who went to a dyno and had a guy dyno tune it... and he took his predator along to get a AFR comparison...

The Predator AFR value at WOT matched what the wideband was reading...

ttfwiw...
