Love CA / Hate CARB
I've had my tune for a while, and I've put off datalogging anything until I get a wideband installed. Well, I picked up an AEM wideband A/F and just started researching what I would have to do to install it. Basically, it would take either a bunch of custom fab work or a new header, which isn't an option for me (I'm in CA). So, can I datalog my car to get a better tune without the wideband? I understand it wouldn't be as good, but it's looking like I don't really have any other options.
