Report Tuners Rejoice! Free Tuning For M4.4! in Performance Modifications Posted June 30, 2017 9 hours ago, razorx said: If you flash that ECU with the right bin, it will work. You have to disable the egr and other non 850 parts in the bin. You cannot plug the other ECU in without disabeling the Immobilizer. The bins on the wikia already have a disabled imobilizer. Thank you razorx, I'm hoping to start getting into this project soon then i can offer my own input/help others. I'm good at solving issues being in IT i just have to do some more research. Any advice?
