213E OEM software: The best NA mod...

EAS wrote

Biggest gains will be seen on early builds (>180E), or M3s that have never been updated.

Gains from updating from 220E=>231E will be very minimal if any - about ~5-6hp.

You mean biggest gains will be (<180E) correct?

Typo, you're correct.

I have an 08 M3 (stock except for a performance air filter) and am unsure of the software version although I don't believe that it was ever updated. I am scheduled to replace the plugs (I have 46k on the first set) and check on, and if necessary, update the software at the end of this week.

I had a dyno run today just to get a baseline before any changes and it recorded a peak of 336 on the best run. I don't know anything about the dyno used, but am wondering if this sounds about right for a stock car.

Mine made 350 WHP with filter, pulley, HFC x-pipe, and axleback on old software. Your numbers seem to be pretty good.

I've just plugged my evolve r cable in an it would seem I'm running Jurassic software. As far as I can see I'm running 50e software looking forward to having it updated and tuned. It's gonna feel like its been sc'd

Updating from 050E should make your M3 feel like a new car. It's quite a stretch.

You guys need to figure out how to do this remotely. I'm taking my M to the dealer thursday hopefully i can get the SA to update software for me.

I agree with EAS on this one. Chances are you will feel a nice improvement between 50E and 231E. If not power wise, at least drivability and smoothness.

Keep us posted.

231E can be applied remotely with HEX flash cable.

How much is the cable?

I have 080E software, the dealer strongly advised against updating my software when I asked them just a few months ago. They said my 2008 M3 is too old and the update which might take few hours might fry the module. I just got the Evolve remote tool, and I am wondering if it is worth the risk to update the software before the tuning.

Fry the module? lol

Current software version has zero impact on a potential issue or not.

Dealers do not have the ability to target specific modules for updates, the entire vehicle is updated (depending on service pack specifications) as a whole. It sounds like they simply did not want to perform the update for you.

Evolve has stated in the past on they can provide the update for you, it would be best you contacted them directly since you already own the tool.

Getting my software updated by the dealer this Saturday. SA told me about two hours for the update and is charging me $188 for it. Not a bad deal, I don't think. My car is a 07/08 build that has not been updated yet.

i think i have also e50 2007 so it will be a huge gain, but someone said that u loose the exhaust rumble and extra gas.

Is it worth it?

Definitely.

Does anyone have a dyno sheet of an 08 M3 with the older version that does NOT have any problems like the one did on page 7? A healthy 08 w/E80 software E92 M3? Id like to see a dyno of before and after on a stock 08 that has no problems. My car is getting serviced as we speak and they quoted me $200 for the update. I'm skeptical after reading the entire thread. Thanks.

I just got mine updated today. 3 Hours of doing it. 140 bucks Car feels totally new. The biggest change I noticed was steering feel. It feels heavier and much more planted to the road if that makes sense. Mine is an 08 that was never updated. I definitely gained some horses according to my butt dyno!

Could I assume that all 2013 M3 have the newest software loaded?

If I currently have a aftermarket tune on my M3 and I bring it in to the BMW dealer to get 231E installed on my ECU, will the dealer notice the aftermarket tune on the ECU in the process of overwriting it with 231E? I know I will loss the aftermarket tune in the process, more concerned about losing my warranty.

Is there any chance I need this on my 09/2011 build date 2012 MY e92 m3?

I need to double check my records, but I don't think i've ever been updated. If any vendor sells a cable and can do this remotely, PM me.
