As above

I have been sitting on this for a while, and am never going to use it.  It's the v2.xx version of the firmware, so the 2G plug can be cut off and a 1G can be wired in place, or a conversion harness can be made.  Either way, it comes with a GM MAF as well, possibly two (can't remember how many I have).  I'm in Ottawa, Canada, but I'll ship it w/tracking and insurance.  If the shipping comes to under $50, it's free.  More than $50 and it'll be at the buyer's expense, but I've rarely seen that happen.
If anyone wants pics I can snap some and upload them tonight, but it's pretty much a standard MAF Translator, lol.
