Dyno tuning; tail pipe or LC-1 best?
I've noticed that a lot of tuners use the tail pipe for measuring AFRs when tuning on a dyno. If a car has a wideband would it be better to measure the AFRs from the wideband or use the calibrated tail pipe sniffer?

Thanks for the response. I know there is only a few feet difference between the LC-1 sensor and the tail pipe sniffer but I was concerned that the tail pipe sniffer might not get as an accurate reading.
Wouldn't the catalytic converter screw up the tailpipe reading? I mean most wideband manuals specify the sensor to be placed before the cat.
^ That's IF there is a cat.
I would say the LC-1 would be the best to read off of. Especially if you do any logging when NOT on the dyno since that's the only reading you'll be getting to work with.
