I live in MA where our emissions is just stupid...

The car has to be able to plug in OBD II.

So I'm thinking of swapping the Autronics for the test with the Stock ECU just for the emissions tests.

I have An ECU, but it seams as though the immobilizer is set. Would it be cheaper to have the dealer reset it? or buy a Ecu and the other unit (i forget the name) that came together?

THanks.
