OE Tuning vs. Active Autowerks ECU Tune
Like to hear some opinions on these two tunes. It looks like OE Tuning has Active Autowerks beat on the Dyno, but is this tune safe? What are you running and for how long...

My opinion is obviously bias but I would like to chime in none the less. Our tune/dyno reflects real world gains done on our in house dyno. On a NA BMW there is very little HP/TQ left on the table and we feel we extract that power the most reliable way possible.

Been running it since 5-1-10 and the car pulls all day long.
Im all for a friendly comparison, here is a dyno of a z4si (same N52 as a 330) done on a Dyno Dynamics dyno, so its a real world number and not inflated like a dynojet. z4 3.0si We do a full Valvetronic tune, which is different then just adding more fuel and a sharper throttle like a PBX or others do. |

This has the potential to be an awesome discussion! Would love to hear from both tuners exactly what parameters they can tweak, such as Air/Fuel, Ignition Timing, Valve Lift, Valve Overlap, Throttle Mapping. Would also love to hear what is different in the programming between 330 vs 328 vs 325. We know the displacement, bore, stroke, heads, cams, and compression ratio are all the same for all three N52 cars. What is different inside the ECU?!
Never saw that Youtube video before. That is a nice dyno graph for a stock 328. Can a 325 see the same peak numbers? If not, why? |

I don't know if the tune is safe for the engine longterm. Seems far too invasive regarding the Valvetronic etc. Good luck and hopefully your engine doesn't blow down the road. I'm not sold, especially with the prospect of pulling my own ECU and shipping it across the country. That's a dealbreaker.

You are most likely correct, but still, pulling my ECU and shipping it isn't in the cards. Anyone wanna invest in a flashing station and a GB for this?

There are things far worse for your engine than one of these tunes. If Air/Fuel ratios are kept in check, there will be no harm done to the motor. Extreme valvetronic tuning could bring up issues with valve float, but what we are seeing on that front is very mild at best. I'd say most of those gains from OE are from tuning the AFR anyway.
Either way, both options will give you a decent gain in power. Honestly, they are very close to each other, and I'd just get whichever one is more convenient for you. |

AFR's Throttle response Valve Lift/Drop for Intake/exhaust and Timing Timing is where most power is to be had, and We have played with some VERY aggressive timing curves on my personal car - and there is room for more power - but the car is running on the ragged edge at that point and is 100 octane dependent. You guys need to remember these cars are able to run as low as 87 octane gas, so from the dealer it has to be able to adjust timing for low octane and bad air. The everyday person doesn't care about what gas they use, and are not in to tuning. For the enthusiast such as ourselves, we use 91 at least, all the time. Or anything higher we can get our hands on - so when we tune, we tune to have 91 as the lowest octane rating - allowing us to run much more aggressive timing and enable the car to rev and pull all the way to redline. |

I am interested, but the lack of information is kind of disappointing. The one dyno for the z4 is nice, but how about on a 325i or a 328i? I think everyone is waiting to see dynos from the public vs. the car the software was tuned for. With software the gains will change from car to car. It would be nice to see a few dynos before and after install, but most people are unwilling to spend the money to do that.

Our Performance Software also takes the vehicles Valvetronic into accountability in our Performance Tune. There is only a certain limit which these N/A N52 can be tuned to obtain the maximum power without compromising the safety of the motor. Our Goal with our Performance Software is to Increase the vehicle's Performance but to maintain driveablity and reliability under all climate and altitude conditions. Also our Performance Software provides a much smoother increase of power especially in mid-range and throughout the entire RPM Band, as you can see below on a recent installation of our Performance Software on a 328i on a 95 Degrees Fahrenheit day in Miami on a Mustang Dyno. As being one of the longest reputable Premier BMW Performance Tuners in the BMW Industry our Software Engineering Department has developed Performance Tunes from the E30 325's to the Current X6M's.

(would it be custom tuning if I add a larger throttle body?) |

Thank you both for providing good info and healthy competition, you guys are both above the board awesome, I don't think we can go wrong with either one of you. Other than the tuning location, what are your policies as far as if the dealer reset the software, what kind of coverage you guys can provide?
I noticed the AA dyno was on 93 octane. Here in CA I can only reasonably find 91 octane gas. Everything being equal, the OE tune does seem more aggressive. |
