This has been posted on a couple forums that I frequent lately. Its an incredibly cheap wideband O2 driver. Has logging capabilities.
If you can put it together yourself $45+10 shipping. Also need a wideband sensor, which you can find for 50-70 if you shop around.
After building my megasquirt I'm sure this wouldn't be difficult at all.
For someone trying te tweak their modifications maybe?
I wish I had found this prior to buying a LC-1 last winter.
