So probably another idiotic question, but I need to ask as this is really the only sticking point for me versus getting for instance an SSTT...

When I do take the car into the dealer, the process of uninstalling, then having to reinstall the tune (what, every 3 months for oil change?)...how long does it physically take...Ive read 10-15 minutes, ive read 45 minutes, and I understand that it depends on your familiarity with a car...but for someone decently handy, is this a general pain every time I have to take the car in?

(i.e...what tools should I stash away in the trunk to keep with at all times if something odd were to happen and I needed to get towed in...)

and apologies again as I'm sure this question reeks of n00b, but thats what I am to this topic

It seems as though a few guys out there are seeing big gains from an intake, and if I recall, helix is/was developing an intake. You believe that the impact is insignificant enough for the ecu to adapt as if it were just an aftermarket catback? Question 2: No maps for 100 octane? I'm rather jealous, seeing that I probably live 15 minutes away from the only 100 octane gas station in my region
an intake or cat back exhaust gives slightly better power(1-3%) over the same general power curve as stock or modified tune so the factory DME can adapt accordingly and does so very well. items such as a very effective intercooler or downpipes drastically change what the DME is programmed for in regards to air density and/or exhaust flow and spoolup so custom tuning is required(but may not be neccesary) to see the full advantage of these mods. I hope that explains this a little bit.

Honestly, Ive taken my car apart so many times I could do it blindfolded. That being said, I do not want to remove my piggy back every time I have to go to the dealer. It would not be 10-15 minutes, more like 20-30mins. The best part about the Attache is the fact it has the ability to switch from the power map to the stock map in the matter of seconds(via self installed switch). This means the dealer will have no clue a piggyback is in your car unless they physically go into your DME housing(which they never have to do really) even if they drive your car.

If thats not good enough for you, get the SSTT. Its way more convenient to remove if thats your main concern. If you get past that worry and realize that the Attache will give you a heap more power for only a couple hundred more, then give Helix a call and get on the list.

+1

I don't even bother with uninstalling it. Especially if you're only going in there for an oil change. The only thing that would make me uninstall it when I go to the dealer would be if I needed some warranty work that is affiliated with the DME, otherwise, I just leave it in.

I have a request that I think would provide interesting results and generate more support for the Attache then there already is.

Is it possible for all of the beta testers to get a dyno done with the Attache?

I am asking about this since it always seems that the tuners car has much higher numbers then the rest of the customers using the same product. This applies to every tune out there, and I am not naming specific ones so don't flame me.

Do you guys think something like this is possible? Thanks in advance for any help or consideration.

One other thing to keep in mind is that BMW's scheduled oil change intervals under warranty are retardedly long. They recommend them every 15k so unless you do a crap load of driving you wouldn't have to bring your car to the dealer every 3 months.

Off topic: Is it OK to get the oil changed somewhere else besides the dealership?

There are some situations that will require uninstalling the Attache. IMO, if my fuel pump goes, I wouldn't bring the car to a dealer with a (any) piggy-back installed. Going back to a stock map may suffice for most other cases though and wouldn't even matter for regular maintenance checkups etc.

I change mine every 5k miles at home with mobil1 0w-40 and an oem filter. I do still plan on taking it into the dealer every 15k for the recommended oil change just so that they can't give me any BS if something does go wrong and I didn't have any documented service even though I was doing the changes way more often then they do.

I agree with you 100%. Personally, I would take out the piggyback out whenever I brought the car in for service, but that's just me. I was only commenting on how he said that he needed to bring the car in every 3 months for an oil change.

+1. If you can't do it yourself, there are places that will do it for basically no money. Just go get the filter and the oil yourself, take it to them and watch them to make sure they actually do it.

If I have a chance, I will do it again to see if there is any loss in traction or if it was the road that was uneven (which I doubt, since it was on 295, but who knows ) that caused the symbol to light up. Btw, not sure if it makes a difference, but I left the DSC on.
Are you saying the "shittiest traction" with the caveat that it's freezing out? Granted, I admit I have no idea what tire the 17" RFT is, but the stock 18" RFT, in the warm, at least has half decent grip (as it shoudl for its stupid low treadware rating). In the cold, they are like rock and a different story...which could be your issue (but my hunch is the 17's are all-season, not summer only like the 18's, so that shouldn't be as much of an issue).
I'd almost be willing to bet it was some bump or undulation you hit on good ol 295 that lit up the light for a second...it seems to happen pretty easily. Curious to see if you can repeat results.

I'll be doing a dyno when I have a few more items installed. I'm hoping to have them all in by mid to late Feb.

Well, hopefully some decide to. Especially the ones who have the Attache as their only mod.

I should be one of those. My car is completley stock with nothing done.

And I already baselined at 300. Im using the same dyno as before when I get mine put in, the same SAE correction and all that jazz..and we should see what she puts out, crank hp wise.

He can. I did it myself in his car..it will just throw the traction light on and cut the power for a section.

And 295 is pretty smooth. We werent blasting over the concrete expansions in the bridges and stuff..what idiot would do that lol.

Hey Scott, your car really moved on 95 though...and thanks for rear fogging that asshat in the TSX that kept tailgating me.

I cant wait to get mine to test auto vs 6mt..
