i found a tuned ecu option for the same engine as the etecII aveo overseas, and there are US dealers that can install it. But we need someone to test to see if it works. (this would require buying a second ecu just in case, <$100 off ebay, just to be safe) The tuner has already stated if it doesn't work (they have a satisfaction guarantee) that you wouldnt need to pay them for the tune.

The chip is advertised for $350, so if it works you would have $450 into the first one. (you could probably sell the second ECU tuned on here to someone without a local dealer). If it doesnt work, you spent $100 and fried an ecu. (i also said to put the ebay ecu in for the tune to "save" the original for backup).
