You got a link for your Catted DPs please??
We have the same issue with our Gas turbines and seal gas analysers. If there is no flow accross the analyser it gets posioned and reads full scale. I reckon something similar is happening here. Lambdas need a flow to measure. Micro cats wont work for long unless you put a flow across them. I think you would need a feed and return so exhaust gas passes over the micro cat. Not that hard to make but like been said beofre until they can be mapped out Hi Flow catted is the easiest way to go.
