TTimlin Posted February 3, 2008 Share Posted February 3, 2008 I have a 2001 GS430 and would like to purchase a programmer/scan tool. I don't know much about the import aftermarket companies and who would make a (laptop to car) plug-in system with software for this car. Also, I would try to stay away from super expensive set-ups like the AEM Engine Management System. Anything affordable? Thanks for your help! One more question: Would a programmer change transmission controls for shift points, etc.? Quote Link to comment Share on other sites More sharing options...
