How accurate is a DYNO's A/F ratio Probe?? You know the ones that get stuck up your pipe on the dyno??? I have had cars with rich O2 readings and no KR read A/F ratios of almost 16:1 <img src="images/icons/confused.gif" border="0">

Re: How accurate is a DYNO's A/F ratio Probe?? By the time the exhaust gets back there, the mixture is cooler IMO. So it's not as accurate as a reading up front but it's probably over 80 to possibly 90% accurate.
As long as the A/F wand is in there securely I would go with that over the 02's.
