S65 ECU Upgrade
I am thinking of making an ECU upgrade to my 2008 S65, but I am concerned about warranty issues. I have a few months of factory warranty left, and then I have a Lexus Platinum extended warranty.

Anyone have experience with their warranty being voided after having an ECU upgrade? How likely is it that for routine stuff it would noticed by the dealership? Obviously if the engine blows I need to re-flash the ECU before taking it to the dealer- but how about more regular issues?

Have it done by RENNtech at an MB dealer. MB of Orland Park, for example, does RT work. I bought my '07 S65 from them with stage 2 RT and it came CPO.
