I've been searching for DIY wideband o2 sensor options, so perhaps I can come out at around $100 for a wideband. I know about the lc-1 and that is my next choice if I can't find anything else.
The PWC board isn't going to be out for a while from bowling grippo, so I'm not even counting on that.
So far I have found the diy-wb replacement in australia, techedge, but it seems like their prices (including shipping/ sensor) will come out at just about the price, if not more, than an innovative lc-1.
I wonder, if there is a way to run a wbo2 off a laptop? Would that make sense? maybe only for tuning, but still. I'm not a computer guru, so I can't even begin to think where to get started on something like this, but is it even possible?
If there are no other cheap alternative wb kits out there i'll just have to go for the LC-1.
