Throw it on the dyno and have at it.

Lol ok

I have a dyno shop, I have the time. You boys want to throw down let me know.

Frankly, a little healthy, good natured competition would be great

I'd love to see a comparison run on same dyno, same day, same condition, same non-biased operator, same mods, between the two tunes - regardless of the outcome

I'd be more than happy to volunteer my car, or even just to be there in person - if only I wasn't clear across the country.

Oh, you should video the runs too for just a little added flavor

100% correct. The most amazing customer feedback from the N52 and N62 tunes from AA. They are amazing, that is it!

Very interested in the outcome of this, some friendly competition dosent hurt !

[Modded328FTW]

More data is needed for this OFT tune imo. I am not convinced at the results yet.

Competition is good but false information is what leads to tuner wars that benefit no one.
AA has been in the game for a long time supporting the N52 platform when no one else was stepping in (Vishnu included).

I have not seen any other run charts (till today), & naturally assume that AA would send me a correct chart...

The runs in the link you supplied are from 2012, IDK why a run from the end of 2013 would be that different?


Not arguing the point, just wondering why the differences in a later chart


At any rate, I'm happy with the OFT compared to what I had, the capabilities of the unit, & the price. If there is room for improvement, I'm sure Shiv will find it over time, I'm fairly certain the AA tune didn't squeeze every available drop on it's 1st go around, & it's been out for quite a bit longer than the OFT

Valid points. Maybe AA can chime in a bit and give some more information on this.

Are you looking to possibly have your own custom tune installed since you now have the unit? Custom maps will get you the most power if you, or someone you know, can tune n52 engines properly.

[E93FTW]

AA FTW! I felt the difference right after driving off the AA shop parking lot. It really works.

One of you guys (andrew or shiv ) should post dyno graphs with different AFRs so we can see if there is any difference in output

I got fairly involved with doing my own custom tuning/tweaking with the GM LS series of engines using LS1Edit. Both my GM cars have been custom tuned on the dyno numerous times over their history of engine mods and for purposes of further refinement

There's a lot to learn & a ton of reading to know exactly what to change & what effect those changes have on the power & way the car runs. Just adding bigger injectors opens up a shitstorm of possibilities & multiple sessions on the dyno to get it just right

I did find that individual custom tuning of your actual car is way better than a simple 'canned' tune - even if the car that was used for said tune has the same mods as your car. It will get you close, but there's always an opportunity for squeezing out that leetle bit more

There are a myriad of things to do mechanically with LS engine to increase power. You just have to have a vision & start heading in that direction with tuning along the way at every step. The engine in my T/A is actually a Lingenfelter 427 LS, plus there is NoS on top of that. Doesn't seem to be much that can be done mechanically to improve the BMW N engines short of hanging on a turbo, or SC (if there was one).

Don't know if I want to (or have the time) to relearn a different engine family at this point - I may be just content with the tunes afforded by Shiv.

Currently I know of no one in my area experienced with tuning the N52/N51, but there are quite a few of us around with knowledge of the LS engines. We would need to start up a Tuning Section on the forum similar to the Coding Section - there's usually a wealth of info afforded by different people as you go thru the learning process. I'm sure if something like that started up I would get the 'bug' again.

I would say that it's nice to have the ability to tweak tune using the OFT if I ever decide to jump in. Guess I would also have to find a dyno in my area that is set up for AWD cars also...

not trying to say anything bad about anyones tune, but i had a very very bad experience with AA's sales department back in November

Agreed.

I'll post my OE files with A/F tonight. I think Shiv is right about them at least...

Sweet

[bimmerquick43321]

would be interested to know where does the AA tune stand in regards to automatics and the removal of the torque limiter? This for me is a game changer when it comes time to racing, as my car simply drops out of the race when the transmission shifts into the next gear, I can feel the power drop and see it with my eyes as the car I was right next to me starts suddenly pulling suddently, however if we start into that gear we're side by side....

What you are experiencing has to do more with the speed of the transmission (or lack of) and gear ratios and not a tune.

Yes the slowshifting automatic doesn't help indeed, gear ratios not an issue, actually better than a manual btw., I fall ~5500rpm if I remember correctly from 3rd from 4th, so quite in the powerband.

To be honest if I wouldn't of heard that there was a limiter on the transmission torque converter, I would of just thought that it's because it's not shifting fast enough, but I guess from what shiv said, there's more to it.

[Eagle1oh7]

We need a transmission flash next for us lame ATers lol

[SDemetris]

I think the thing that proves that AA does not just advance ignition is the graphs of before and after with 3 stage intake manifolds. dis4life was a member a while ago and got banned for... idk why actually. but he posted before and after graphs and their tune and the dip in power from 3k-4.3k was fixed from their tune. im pretty confident that ignition timing would not do that

You should test a PBX then. Stock vs. PBX same car same day dyno. Notice AFR change.
