The unlocked ECU came already installed by the previous owner with a whole host of upgrades. Cams, ecu, exhaust, aircleaner, suspensions,. I added the bevel box cooler and oil cooler kits and the magna flow exhaust. I dont think the ecu came from g56. I will look in my file and see where it's from and the price paid. I think it may have come from s&s direct but I very well could be mistaken. Will advise.
