And implicit in this is the fact that 512-bit keys can be factored pretty quickly on modern computers. Get something like a threadripper cpu with an nvidia graphics card and you can probably factor a key at home in a little over a day.

1024-bit is still out of the realm of possibility outside of the NSA, though I suspect in the next decade or so we'll have consumer-grade hardware capable of factoring those keys. 2048-bit and higher, and you'll probably be waiting for quantum computers.

Pretty much what I wrote above. There's probably a small bump in power, but otherwise I can't ever have a MAF failure.

The throttle would be pretty easy to tweak. Is your car 6mt or auto? I haven't noticed any real 'lag' with the 6mt, but I think a lot of it comes from the custom tune.

6MT. I perceive the throttle to have a delay when first applied.


Could this be the throttle curve you mentioned?


Have you tested your tune on other cars? Did you raise the rev limit slightly? (can't recall if it was yourself or someone else testing this)

I can raise the rev limit but all of the free files have stock limiters (since they are based on stock tunes).

It's been so long since I've driven my car with a stock tune, it might be other changes (there's also a throttle position map). One of these days I'm going to reinstall my MAF and flash the stock tune to remember what it was like (well, I sort of remember - I thought it felt neutered).

Do you have an ETA for non stock tunes with lifted limiters and the mods for transmissions too?

I'm going to have some time to install my 3IM so I hope to get the modded tune put onto my 328xi

hass - just finished installing the 3IM, and was checking bimmerlabs for updates and the link to the USB / OBD tool - only to discover the site is down. you are probably aware, but if not - heads up.

thanks - got the files.

2 questions:

is it worth getting the 0Pd data file from my car before flashing the RSA Delete / 330 firmware?

and, any progress to report on the web based tuning system you mentioned? still interested in looking at tables and all that fun stuff. glad to be a low functioning beta if you need one.

No, you don't need to do that. the RSA delete already updates the program.

I don't have the web based stuff available yet - there's always 10,000 other things that need attention first.
