hah, funny you should mention that. Im working on one of those right now.

They are illegal to sell as of late last year so only real option is to make them. Even ebay has nothin.

edit: that is actually not what Im building. That particular DIY will not properly oscillate the o2 sensor voltage, so many ecus will still throw codes that the o2 sensor isnt working.
this is the one Im building
