Got an old ATS ROM Tune and thinking of upgrading to a full stand alone? ATS is offering $500 credit for your old rom tune when your purchase a Link or ECUMAster stand alone ecu, or any of our stand alone combos. I am currently working to add this option to the options menues on all the ECU's and pacjages on the site, but if you see one I missed please email us at sales@atsracing.net  Just purchase normally on the website, check the rom tune trade in option and then ship us your old ecu. Once we get it we will ship your new stand alone ecu.
