What kind of coverage accross the US for your current dealers can we expect into the future. The site has limited authorized bmw dealers, will this be expanded?

If you run stage one, throw a code and flash back to stock for service work, is that code overwritten or is a separate bt tool needed?

Rob will have to address your first question when he gets back onlines.

The coverage of Professional BMW AccessTUNERs is going to depend on what facilities are interested in generating customer calibrations for these vehicles on their chassis dynos. We will update the dealer section of our forums as new BMW Professional Tuning Facilities are added. This will take time, so please do not expect any immediate updates until more external vendors use and prove this technology.

The AccessPORT is capable of checking and clearing stock drivetrain DTCs. Whether you want to uninstall the device before going to the dealership or not is entirely up to you.

Christian.

We do not change any of the ECU startup routines at this time, it will function as stock when if comes to start times and priming of the fuel system.

1. Is this flash detectable by the dealers when you take it in for service?!?!

2. What happens if you have the Cobb flash installed, then when you're driving your HPFP fails or your injectors fail, you get a check engine light or HALF-ENGINE light...
When the dealers scan your car for codes, will they see that someone tampered with the DME ??

If so, can we un-flash the car while we are waiting for the tow truck? Will the DME allow an un-flash with a check-engine light?

1. When installed it is likely the dealer, if they really went looking, could find the flash. We recommend you uninstall before your dealer visits.

2. The AP will definitely uninstall when there are check engine lights and most certainly can be uninstalled while waiting for a tow truck.

i have friends in the Z car / subie communities running cobb and i like the product; might even win me over soon but i'm very curious

The ECU retains is ability to adapt to different conditions such as bad gas and altitude. Modifications such at downpipes will require different maps which we are working on making available as different stage maps.

We recommend a battery charger to cover the worse case scenario such as a car that has been left out in the cold without being driven for two weeks or car with a super week battery. A car driven daily with a healthy battery will not require a charger to install or uninstall. Changing maps are so quick, there is no need for a charger to be attached.

I have a 2009 E90 335xi LCI with the factory PPK tune. Will this be saved as the default map and reinstalled after an AP uninstall procedure?

Features like speed delimiter, DP fix etc. are also important. I have the BMS fixes, but would love to be able to code, change map and analyse/modify from the OBD connector.

Well, anyway, my Quiafe LSD is being installed Tuesday, so at least I'll have that to look forward to while waiting anxiously.....

The question is how come JB4 and procedeV5 support both EUR and US 335 while AP can't ? I know a flash is difference from PNP but is that also affect? Can we just the current AP on EUR spec and wait for a EUR map later?

I could be way off the wall on this, but I think the reason is:

Piggy back systems intercept and produce signals and code that modifies what the ECU see's, therefore piggies can be used on a wide variety of cars. A flash is a complete re-write of the ECU's coding.

COBB has only US cars to work with, they don't know if the coding between an EU car and a US car is the same. Just think of what could happen if you loaded the firmware and it crashed your cars ECU...

OF course I could be off the wall like I said, so maybe an expert could chime in if I'm right or wrong..

If you guys at Cobb HQ in austin need a 2007 335i to test on let me know

[E92TTKING]

1 question- Will the dealer be able to trace the tune?
The jb3 and 4 are untraceable when removed.
This is the major decision factor for me

Does anyone read through entire threads anymore? I know Cobb will answer this question again, but on page 3 of this very thread they discuss just that...

As a Dinan flash adopter, I am attracted to this tune because of the ability to reflash at home without having to drive 350 +miles to the nearest Dinan dealer. I am also interested in the potential pop in power vs. Dinan S3. With my car coming off warranty this year, that isn't a concern. So a couple of questions:

1. Will it safely overwite the Dinan tune, or will you have to get it flashed back to stock first? and

2. If it can flash over the Dinan tune, when you flash back to stock, will it restore the Dinan tune or to stock?

Thanks in advance. It looks like an exciting product.

That's also something I'm a bit puzzled about, I thought it was either MSD80 or MDS81 and otherwise EUR and US specs were basically the same.

Anyway GIAC seems to be able to flash both US and EUR spec cars, so I'm sure Cobb will get to it sooner or later. IMO they are probably just waiting for the right business partner in EUR.

Army335xi has the right idea.

A piggyback just modifys signals sent and received by the ECU. So it can be used by a USDM ECU or EDM ECU.

When dealing with flashing, like Army said, your completely rewriting the code (aka ROM or IMAGE) on that ECU. Now, when flashing you need to know the type of ECU and the exact coding of the ROM or IMAGE on it. Even if you can flash/modify a USDM ROM on ECU MSD80, you may not know the coding for the EDM ROM on the same ECU, and therefore would be unsafe to try to flash or modify the code.

I dont know if that exactly the case here, but maybe that helps explain more.

Having never touched a car with a Dinan flash, I cannot say with 100% certainty. I can say I will be happy to personally walk you through the process to find out using an AP.

There are three things that can happen:
1. The AP saves off the dinan flash an puts our tune on.
2. The AP says it must overwrite the tune meaning, if you continue, the Dinan flash will be gone forever.
3. The AP is unable to flash over the tune requiring the car to be returned to stock first.

In the case where the AP overwrites a tune: The AP, having never seen your actual stock ROM, will put back an appropriate stock ROM that may or may not be what your car had originally.

I hope this helps,
Rob

I believe the only modification was DCIs. Most all of these graphs are in our dyno database if y'all want to peruse it. http://accessecu.com/dyno/

[Tortfeasor 335xi]

Those are some solid looking dynos for the 335xi. Looking forward to the final product. Any data on A/F ratio? Any dynos of bone stock 335xi's?

[sA x sKy]

If the 335xi is getting those numbers, I'm going to be really, really happy.

[PKumarM3]

335xi owners are in for a real treat. i am hoping that the xi a/p will be ready by february!

AFR should be a very safe 12.0-12.5.

hahah i don't like to rush tuners! but in that case




whenever i hear accessport i think of that Hitler GTR video where the lady consoles the other saying "don't worry, he won't sell it, he just ordered his acess port"

hahaha
