I've noticed with the free version of Crome it does not have the option to modify the lambda table. I researched a little on this and can only find one post where the guy says as long as you use a O2 that has its own software, itll work. He stated the PLX doesn't have their own software but the LM-1 does; can anyone confirm that it'll work with the free version of Crome? Also, can I use an independent datalogging software instead of using Crome's? I know some of you guys are saying just buy CromePro; but after looking at the features, I don't think its really worth it for me(that is, if I can use an independent datalogging software).
