    335d: Evolve Vs. Renntech tune?

    I am a new 335d owner and heavily weighing the options of an Evolve vs. Renntech ECU tune.

    One last important issue in the decision; if I sell the car, or need to revert the ECU back to factory programming, will VS motorsports and Evolve be around over the next few years to do this for me? If Evolve pulls out of the US or VS motorsports goes out of business or drops the Evolve tune, who in the world would be able to revert my ECU back to stock, or even update it for that matter?

    Renntech has been around for quite a while here in the US, I get the impression they do not carry such risks, but I could be wrong.

    I have no affiliation with any automotive industry whatsoever other than being a BMW owner.

    I don't see how you could go wrong with either.

    Why wouldn't Evolve be around? With the diesel isn't there a flashloader to revert to stock anyway?

    Flashloader not available in the USA, will not work on US spec BMWs. Only dealer in US for Evolve ECU tune is VS motorsports in Illinois.

    Interesting, does Renntech have a flashloader in the USA?

    I believe that is accurate - I don't think anyone has cracked the US DME for the 35d remote OBD flashing.

    Correct RENNtech has bench flash only, I was there when the flashed my car. And believe me opening the ECU is not for the novice, leave it to someone that knows!!.
