If I replace the second lambda(after the cat) with a wideband and then wire it to the ELD input on my euro CTR kpro. I can then datalog wideband A/F?

You don't want to put it after the cat as it will give incorrect readings. Using a PRA, you cna set it up just like you would an s300 using both narrowband and wideband outputs to the ecu. http://www.hondata.com/techplxwiring.html

Sorry, I should have written that there is no cat but would be placing the lambda in the second lambda position :oops:

Thanks for the help.
