I disagree. At the end of the day, it is just an s54. Remove the ecu and you can do anything you want to it. The ecu does not know what car it is in. Standalones have nothing to do with the other rolling up window or any of the other gadgets that are on a modern car.

AEM makes a unit. Andrew Lang, as well as many others, can wire it up for you in a day ($1000). http://store.langracing.com/aem-infi...gement-system/
