Almost 2 years on mine and still working. It was used when I bought it. Funny, I asked a mechanic at the Caddy dealer my wife works at if it would be a good idea to change the O2 sensors on my truck since I'm getting near 180k. He laughed and said if they are still working then let them alone.

The o2 sensors on cars and bikes are not wideband.
Yes, many are.....some are wide, some narrow...some are to ignite gas, etc....

Your Caddy dealer mechanic is a moron then. Come on Smokin, you're a car guy / engine builder: How many times have you seen cars dyno and the calibrated accurate wideband on the dyno dissagreed with the cars O2 sensor? I've seen it often enough! Not to mention replacing stock high mileage sensors and suddenly getting better gas mileage- with no other changes? I pay very good attention to mpg: always have as I always seem to work a long damned ways from where I live.
BUT that was not the reason I posted that article: the point was that even widebands with the exact same sensor but with different software running them can be off: The article showed most of them off by an average of .75 of a point.
Innovate XD-16: perfect
AEM All-in-One: perfect
Fast A/F Meter: 0.5 off
FJO Controller: 0.5 off
PLX M300 A/F : 1.0 off
Dynojet Wideband: 0.75 off
Zeitronix ZT-2 : 0.75 off
NGK/AFX Meter: 1.0 off
In other words: take the PC Autotune to a dyno ASAP after buying it and compare the AFR of it versus a calibrated wideband. Do a idle and mid rpm reading. Cheapest way to do it is go to a smog check station and pay the $15 or $20 for a quick check. My experience is they are always more than happy to help you out. Then you will know precisely what the meter is reading versus reality and it will give you a baseline adjustment to work with.... though it will not help you find out what the latency is. And the latency is almost as important as the AFR accuracy according to both common sense and the article I'm talking about.

If I'm still getting the exact same mileage I was 11 years ago when I bought the truck, then why waste money on sensors that are not bad? The wideband on my bike has been checked side by side on at least 5 different dyno's and has always matched, not that it really matters. You tune to find the most power regardless of what the guage says.

TRUE. It doesn't really matter if your gauge reads 30:1, as long as you understand where the bike makes power, and you set the bike to tune at that number.
