ECU software upgrade
MB has issued an ecu software upgrade to prevent possible catalyst heat problems.
I have the renntech ecu tune on my 16 s63 AMG
if I return my ecu to stock, get the mb ecu upgrade, then reflash my ecu with my renntech tuner
will the renntech tune affect the mb software upgrade?
Any thoughts

If you reflash with your previous tuned Software, the MB update will be deleted.
So maybe is better to flash the original factory file, make the Update and then tune the updated new file again.
