Active Autowerke Tune Purchase Process (help)
Hey Guys,
I need some insight here... I spoke with Active Autowerke yesterday in regards to thier E85/6 S54 Tune they have available. I talked to a sales person that was very polite, but wasn't very knowledgable about the specifics of the tune (which is totally understandable). I was transfered to their "head engineer" who really did sound like he knew what he was talking about, however I wanted to bounce some things off of you guys before I move further with his requests. I have recently picked myself up a BEAUTIFUL pair of OEM Euro Headers from StarScream . I am still trying to figure out what to do with the rest of my exhaust, but that is a whole other conversation in itself. Anyway, I live in Minnesota where we have no smog/emissions checks at all, so naturally, I would like to run a catless setup with my MC. So, I asked Active's head Engineer if it was possible to completely shut off the Rear o2 sensors as well as shut off the EGT sensor. He stated that it is possible to shut off the rear o2 sensors with certain versions of the ECU, while other versions it is impossible. So then it gets to his request, he would like me to go out and unplug both rear o2 sensors AND the EGT sensor, then drive the car around untill I throw both codes. He then wants me to take it to someone who can read specific BMW codes to write them down and send them off to him. This will allow him to dig into my ECU once I send it to them to locate the exact process that throws the code in an attempt to shut it off. Does this seem logical to you guys? I almost feel as if I am being the guinea pig for them so they will know the exact process to turn off the o2's in the future. Can someone provide me some insight?

I do not remember the name of the engineer I spoke with. O-Cha how long would be reasonable for me to drive around with the sensors unpluged to ensure I throw all nessessary codes. Shall I unplug them at cold start, or let the car warm up first?
Also, spirited driving or normal driving? City or highway? I just want to ensure I am doing this right as I'll have to wait for a good cold dry day to do this given I have 3 feet of snow outside.

Not out of the ordinary, AJ at ESS had to do the same thing for me.

im sending my cat section off to get a pair of bungs welded on by good speed performance so i can relocate my sensors there.....from im told no codes are thrown with this mod.... plus you could see some power gains without a tune.....it basically pays for itself

When I first got the AA S54 tune, I didn't have headers yet, so I opted to get the non-headers tune. After I installed headers a couple months later however, the car threw a CEL within two start-ups. This was to be expected though and I had the header tune done shortly thereafter.
The local AA vendor used a Peake tool to read out my codes and the rep that I worked with (Cal @ JSW), communicated with AA on my behalf and got everything sorted out. I've never had a CEL issue since, and the car runs very well, even after 3 track days Cal has already left JSW though, and he works @ Sonic MS now. But that doesn't really matter for you, since you're not local anyway. |

AA tune with AA Prima Supercharger kit ? Why not?
So the Active Autowerke E46 M3 Prima Supercharger Kit is "only" $6200, but they (Jean) claimed yesterday not to have a Z4M ECU flash despite ample evidence to the contrary posted on this forum.
What gives? I realize the tune would need to be tweaked, but it seems to be 95% there?? How do we incentivise them to connect the dots? I would love to see an alterative to the ESS stage 1 for a grand less, and AA product has a generally excellent reputation. |

I say this because I bought the other set of Euro header off Starscream and have a vested interest in the answer. |

I still have my CEL on because of cats... But it doesn't affect performance wise. Either way, by shutting off the CEL, you'll have to pay 200 bucks and you still won't pass smog here in CA. I kept the 200 bucks to myself to pay for the ridiculous gas price and the awesome 15mpg I get from this car (heavy footed).

they just change the range of the sensors, turning it off will not allow emissions to pass because faults would still be present

It'd be nice to know if there's a clear direction to take. I'm thinking that my Section 1 is going to have 3 little holes in them after all... |

Ah sorry for not being clear. I mean, the tune is great for what it is. But it is what it is; just a mail-order tune
I'm thoroughly happy with mine, but it really all just comes down to each individual's perspective in terms of "worth". To me, it was worth the hookup price since I was technically the first customer outside of AA. As far as the header tune goes, I think the mapping is all the same. The ECU is capable of adapting to help take advantage of your modifications. Just don't expect anything breath-taking. For that, you'll need full standalone and many hours of dyno tuning. Not to mention a very good tuner/programmer Sooo yeah it comes down to what price you're able to get an ECU tune for, and your plans down the road. Like for me, I plan on doing FI down the road. I'm trying to hold out for a turbo app. Maybe I'll offer my car up to a R&D vendor if they're willing to back up their work via contract, such as covering for possible blown motor and any damages to car during R&D process, etc. |
