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.

sorry, should have phrased my questions more clearly.

i've seen 4 stock MSV80 files for my car / project on bimmerlabs. just wondering if i should archive my own stock file in case I need to flash it back for some reason?

Nope.. You can just flash any of those stock files later on - either MI20S or MM10S would be fine.

Only reason to backup would be if you already have some kind of tune I guess. That said, we don't currently give you a means by which you can backup the DME. That might change in the intermediate future

I created a project at bimmerlabs but I'm not able to select the DME. I got a dump of the 116i and would like to upload it to bimmerlabs for you. But thats not possible without selecting a DME.

Here are some additional information:

116i E87 N43B20 MSD81.2

ZB number: 8688008
Program: 8672567A.0pa
Data: S8688009.0da
SW: 0044RD0QID0S
Power class: 01 (N43B20K0 according to NCSdummy)


I THINK these are the files for the 118i:
ZB number: 8688004
Program: 8672567.0pa
Data: S8688005.0da
Power class: 00 (N43B20U0 according to NCSdummy)

I tried to find the power class byte, but without an xdf, damos, ... I had no luck. Maybe the description in NCSdummy is not correct.

Would you have a look at these files?
Can I PM you the original file?

I haven't added support for MSD81.2 yet which is why you can't select it - but if you can PM me with your email, and send me the full dump, I can probably add it.

I flashed the MAF delete tune and thought I'd share this picture comparing the European IAT sensor to the NA MAF sensor:



I'll post more about the tune after more seat time.

Yeah, there should be quite a bit less restriction. Plus no MAF = no MAF failure or cleaning..

Says "delivery might be Sept. 10-20" but I have faith it'll come sooner lol. Either way the cars running fine now.

Flash went smoothly. No fault codes after the flash or after resetting adaptations but my CEL was still illuminated for some reason. It went away on its own after a few drives though. Only oddity so far is the idle randomly surges to ~1200 RPM briefly during cold starts.

Engine seems to have a little more life in it. Runs smoother and feels more responsive, especially in low to mid RPM range. Also feels like there's more low RPM torque in higher gears? Still monitoring fuel consumption but it appears to be the same.

Doesn't seem like there are any downsides to the MAF delete tune so if you have the European IAT sitting around or can get it cheap, go for it!

Basically wire up one end of the switch to pin 18 on that JBE module, and the other to ground. Then wire a second switch to pin 36 (or use a rocker). And then in NCS, go to the JBE module and set "FDS_Switch" to aktiv. Then in the Kombi, set FDC_ID_MONITOR to aktiv, along with either FDC_VERBAUT or SPORT_ANZEIGE (both are the same function, but newer clusters have the second label for whatever reason). Maybe also set FDS_ENABLE, FDS_ID_MONITOR, FDS_CSUM_MONITOR, and FDS_ALIVE_ZAEHLER to aktiv (these functions are only in KMBI_PL2.C08 and C09).




DME will still need programming to enter sport mode, but it's only a single byte if you're using the CAN-bus to trigger it IIRC.
Is this possible with the n55 335 manual?? its annoying that the auto guys have a sport mode but the manual guys dont.

Is it possible to retrofit or code a sport mode?
