Aftermarket upgrades and tuning of vehicles is nothing new. It has been going on since the first automobiles hit the road. And I don't believe it will stop... it will just adapt. Same as when EFI replaced carbs and when OBD and OBDII came along. Tuning lived on.
However, in regards to the 335... with stricter and stricter emission controls (main reason) and careless tuners putting BMW's reliability and value at risk such as the reckless overdriving of the 335i turbos, BMW has to now intervene. They cannot allow an aftermarket "attachment" to severely modify their warrantability, resale value, market segment, and mostly the coveted emissions certifications. BMW has to protect their investment.
In regards to ESS, we have been doing this since '95. We never push any car, supercharger, or software beyond safe limits regardless if we lose the horsepower race to someone else. We test, test again, and then when we are done, we test it again. We may not make the most power, but we do it right and we do it safely. Our products are designed to be reliable, durable, and require little to no maintenance. We program each software and SC kit to make more power, then spend more time to perform within both EPA and TUV emissions standards for global market use.
As for the future, we will continue to offer products that improve the performance of your BMW until we simply cannot anymore.
As of right now, there is no reason to worry about the M5/M6.
While I agree with your statements, that doesn't really provide comfort. The issue is that modification or reflash on the 335's can and for some users has voided the drivetrain portion of the warranty. Which translating to english means that if your car has a VANOS issue, completely unrelated to the ECU flash, BMW NA could stick it to you and not cover you under warranty even though that too is a "known problem" much like the 335i fuel pump problem.
It doesn't matter how "safe" your flash is, if BMW can detect that it's been done (which is what the claims are right now, that with the new version of Progman, they can detect reflashes and piggyback modules) then you are open to attack.
If that becomes true of the M5, no matter what you do that's "safe", I would imagine that it puts our warranties at risk. I just want to know if any of the tuners out there are "in the know" with what's really going on, because the answer makes the difference between possibly buying a flashed ECU, or not buying one... and that of course will effect all of the tuners profits.
Don't get me wrong, typically when I get ready to make performance mods, I throw my warranty out the window, and I accept that going in... but considering this particular car, and it's base power from the factory, I'm really debating if warranty questionable modifications are going to be worth it... with what I'm seeing in the 335i community, it's making me not want to modify my M5 at all.
