ecu is in the upper part of the engine bay on the drives side. you take it out. send it to giac. they chip it and send it back. you then put it in your car and enjoy. o ya you cant drive your car while your ecu is out

 

thanks man how long does it take and how much mula?

 

well you overnight it and i think they have one day turn around and they ship it back. check with their web site and see about pricing

 

you should also think about doing exhaust if you havent already. that would be a nice mod with the chip.
