Hi guys,
Nothing helps in development quite like traveling 3500 miles to Canada to spend a week tuning two 500whp upgrade turbo cars. With big turbos, subzero ambient temps, unlimited meth/dyno time and two willing customers who wanted to push the envelop, we were able to induce load conditions that I could never could come close to replicating in-house (at least not yet!). We learned, first hand, about about fuel/ignition system limits, DME diagnostic quirks and mapping requirements. Something that simply could not have been learned through remote tuning or through testing lower powered cars. Armed with all these new information, we have had our nose to the proverbial grindstone since getting back to California 3 weeks ago. We've kept the results of this testing quiet and did all preliminary alpha testing off-line. Big thanks to Dzenno (RB turbo 6mt), Ultimateracing335 (RB turbos 6MT), badass335 (stock turbos 6AT), loweredram (stock turbos 6AT), enrita (TD turbos 6AT), oddjob (ASR turbos 6MT), and everyone else who provided us with private feedback and datalogs.

And the results are pretty darn good which you can now see/feel for yourself:

Now available for download here: http://www.procedetuning.com/BMW/n54...downloads.html

What’s New:

1) Completely new approach to crank signal processing. This results in a resolution improvement of 800%. Slightly overkill but the benefits will be felt in all applications (smoother idle, resistance to misfire, better ignition timing control, more consistent advance, etc,.)
2) New specific maps for RB turbo cars! The wastegates on the RB turbos are stiffer-than-normal which required a substantial change to the standard wastegate DC maps. You will also notice that the Boost Control Gain value in the user adjustable menu is set to 30%, instead of the usual default of 50%. This means that RB turbo cars must run RB turbo maps. Running standard maps will result in overboost, throttle closure and general unhappiness. With appropriate supporting modifications, race gas and methanol injection, these maps will support over 500whp at 19psi of boost.
3) Revised fuel system mapping which should result in more fuel system capacity in the important 4000-5000rpm range.
4) Procede integrated traction control is less sensitive. This means that it will be less reactive to factory BMW traction control intervention.
5) Now you can temporarily revert back to stock gas level/oil temp gauge display mode by simply requesting a current map display (cruise control stalk bumped up). While the current map # is being displayed on the tach (for the usual 1.5 seconds), the fuel level and oil temp gauges will momentarily revert to stock display. Before this, you would have to toggle through the gauge display options to see the original display options. So this is very convenient.

As always, please read the accompanying documentation carefully. It will answer most of your questions (ie, is autotuning active?, what IC% should I run?, etc,.). Also, this is still a BETA release, so please read the big in red and bold at the bottom of the Read Me file. Those who don't adhere to that requirement will be software locked from running beta release maps in the future

Cheers,
Shiv

YeeeeeeeHAW! Can't wait to load these up!

[**335i**]

nice work shiv, but why it sais BETA when it will be not beta? any ideas when wheel steering buttons going to be active?

I noticed Mac OSX titled files in the zip. Is there a version of software that is Mac native now?

[chumley]

Great, thanks Shiv!

....and thanks to all who helped with the testing!

no those are created when you are using mac . i have the same.

And by the way guys this maps are sick . you gonna love them . i was incredibly surprised how well my car was running after this update.

Looks like my laptop will be taking a field trip into the garage tonight. Thanks Shiv!

Start boost 45%
Maxboost 15.0psi
IC 100%

VK Downpipes/AFE Intake... OEM FMIC!

3rd and 4th gear...




My car is amazing, 3-15 FTW!
I hope to see steering wheel command center asap!

[jpsimon]

looks good man! can't wait to try it out

Looks great. Just a suggestion... don't plot Boost Control DC in the same graph as Boost. It just ends up looking messy

Steering wheel command center controls coming up next...

They are really REALLY good!
One of the best maps i've ever seen.

Yes i'm really satisfied. Before, with 2-14, at high IAT I had problems with IGN Cor (it jags a little bit)... With this 3-15, no one!
Thank u for the suggestion! Great work!

so Shiv which turbo's have been the best for you to tune? What results did you like the best?

[jpsimon]

Gotta be the RB's

[Bakeme521]

YESSS this day just got awesome. Within 5 minutes the UPS man dropped off my new spark plugs and I read this thread. Can't wait to get it installed.

I've been debating between RB and ASR turbos. Lots of customers have the RBs now. So maybe it would make sense to run the ASRs to make sure we have all bases covered. Either way, I'll be running some upgrade within the next month or two.

they seem to both have their strongpoints.

I like that the ASR's have DBB CHRA's.......but they leave the WG factory right?

Nope.. there is now a Forge WG option from what I understand.

Whoa the idle on the car seems to be so smooth now! It hovers lower than the norm that I use to see but yet it really is smooth...Exhaust note seems to be a drop lower than the previous 2-14 maps...THe performance of these new maps are incredible and so much better than 2-14 maps/firmware in terms of smoothness...I was wondering why you have been so quiet lately and these refinements show the reason! No misfires or hiccups, not that I was ever experiencing this issue ever...

[Brey335i]

This is great stuff! I really wish I had my car back from the shop already!

From you guys who have tried it, how does it feel compared to the 2-14 BETA maps?

[dzenno]

I've been running this update since a few days ago, pure joy not a single misfire..great job Shiv

is smoother all the way to redline. low end is soooo nice and enjoyable , car is very reactive and torque is put down progressively but at the same time really strong. For upped turbos after 5000 rpm hell brakes loose till 6850 rpm non stop.

[Sniz]

is 6850rpms the redline?? thought it was higher than that.
