Xcede doing the N55 via the port

[Sherwin@xcede]

Xcede has been appointed as the only Cobb Authorised BMW tuner in Africa. We can therefore make custom maps for altitude & mail to our customers to load via the Cobb Accessport. We also stock the AP's for BMW.

congrats on being selected.

please confirm that when you return the ecu to stock, it uses the bmw stock map and not the cobb stock map. in other words, once you have flashed it back to stock would the software loaded on the ecu be identical to what it was the day you bought it from bmw?

cobb, jb4, procede. nice choices available to x35i owners :thumbs:

As far as I know the Cobb map uses the BMW base map that is on each car and modifies it. So when reloading you wont get a generic stock map but your own. Sherwin can confirm this.

What about internal eeprom data and counters?

Thats important for Motorplan :idea:

^^ what he said :rollsmile:

thats the main reason for my question.

 

[Rolf]

^^ that's NOT the same cake!
Internal e²prom can NOT be read or programmed via OBD .... hence my question .... (we are not talking normal flash content here)

 

[Sherwin@xcede]

The stock map is read off the car & saved. When you go back to stock you load the map that was on the car. There is no flash counters that are incremented. It's a partial write of the map area, not a firmware/progman update. It doesn't count as a flash.

 

[andrewbuch]

Valet mode maps.

Whats this? if its a map you can load when your car goes for a wash/valet so that they cant rape it then thats awesome

 

[Rolf]

Only to clearify NOT to run anything down or stir the soup....

N55 have BOSCH MEVD17.2 system which worx completely different to the Siemens used i N54 1-Series cars!

Are you 100% sure it is like you state? The Infineon Tricore does have e²prom and even partial write is recorded and to my knowledge any access is.....

I'm willing to learn!

:roflol: my bad. but sherwin and george covered what i was trying to get at anyway. thanks guys

just as a matter of interest,am i correct in sayin that cobb units are vin locked,so when you load stage 0 it will give you a DME no.that is specific to your car and your car alone,that bein said every person wanting a flash via obd will have to purchase a Cobb AP unit.Cobb can be reused,though it has to be uninstalled on current car of use to be used on the next so no two cars can share a unit,is that correct?thanx in advance.

Yes doc, each car needs their own AP. It's VIn locked when you read your DME. It's expensive at $895 but you don't have to worry about wires & connectors & all the other associated work with piggybacks.

 

[abmi0000]

Is this similar to the Bluefin by Superchips? I still remember a Speed & Sound review about 5-6 years ago with this product.

 

[h4tch3t]

I had one of those Bluefin goodies for a Focus ST.
Saves the ford map first, then loads whatever config you buy and download.
You can then swap back and forth between maps as and when you choose.
With them you had to email all mods done to buy a reconfigured map to suit your mods.

I do however think that the current BMW systems are way more complicated, and that it could still be detected if youre not careful enough.

 

[Twinz]

Congrats Sherwin.

I use the cobb unit...so just a correction:

The Cobb AP is not technically "VIN locked". The moment you install it on your car the AP is loaded on your particular car. When you uninstall it the next moment you can sell the Cobb AP to someone else and that person can load the Cob AP on his car and so on and so on. But you cannot load the Cobb AP on two vehicles or more at the same time. The intial outlay for the Cobb AP maybe expensive but it is the best value for money in the long run, because you can resell it.

And the Cobb is so dead easy to use. No laptop needed. Just plug in, choose one of the many maps and enjoy.

The other useful thing is the many features it has. You can log plenty parameters and read and delete codes & perform diagnostics etc without a laptop.

Its a great little tune.
:thumbs:

Two questions Twinz:

1. Is the unit locked to the car as long as the software is installed to the car? Can you sell it without uninstalling?
2. Is the mod detectable by Motorplan?

Trust that needs to be clearified for interested parties

   No, you have to uninstall it before you can sell it.
   
2. Is the mod detectable by Motorplan?

Yes, it is detectable as long as it is installed on the car. Donford BMW could not access my DME while the unit was installed, the day that you came to visit me at the dealership. I had to uninstall it so they could access the ecu via the OBD.

Hi Rolf, I actually don't know yet as we are doing our 1st N55 this week-end. So you may well be right. A partial write may or may not be recorded, it's not a certainty right now. But my advice to anyone that has any doubts about motorplan is to just leave their car stock.

Ok thanks Twinz, i'm new to this so I'm still learning the rules.

 

[Rolf]

OK that far I can follow.....

Now to the crucial point:
- the OBD port is handled by the ECU's processor which allows access to the flash and coordinates addressing of the maps (else one could not just change a single map but would always have to flash the whole software).
- knowing this it must be noticed that all read and write operations are monitored and logged in the processors internal e²prom.
- this e²prom is not a separate chip
- this e²prom can not be programmed via OBD

In my humble understanding of the materia, BMW will always be able to detect if boost and rpm have been fiddled with should they suspect such thing and connect their system to the car to transmit data to their HQ

Am I wrong here?

Hi Rolf, I think Twinz covered the the 1st point.

Is it detectable by motorplan, I would say no for normal servicing/etc. It does put some form of encryption on the DME so BMW can't do proper diagnostics, but one can uninstall the Cobb to prevent this. As always my golden rule applies. If you as the owner are not comfortable, then leave it stock.

Yes they may well be able to see if the flash counter has been incremented (not confirmed yet, but may be the case). No they cannot ever see that boost has been raised unless they drive & log the boost. And they don't have equipment to do that. All their equipment does static diagnosis.
