Ryan r was helpful and friendly to talk with
i ordered an ecm for a 2006 pontiac vibe that was sold as "Plug and Play" the module arrived with poor instructions to program sync to the immobilizer. the sync did not work after several attempts and the new unit would not start the vehicle. previous issue was not a no start and completely unrelated. they were late on delivery, slow to respond, falsely advertised their unit, supplied a faulty unit and charged $105 USD to ship to canada. its about $30 CAD to ship it back. now they wont offer a refund or respond to emails. find a local repair shop that does ecm repair as flagship one is a waste of time and money.
Bryan T Good customer Service!
JULIE C WAS VERY HELPFUL IN FINDING MY ECM !!!
