Rookie question - ever a need to flash ROM or firmware to ECU?
Posted: Mon Aug 22, 2016 8:20 am
So I've been prompted and performed a lot of Nistune and ROM pack updates but I still never do anything but change maps and constants on the ECU. Is there ever a need to do anything else when these updates happen?
