Thanks for the FAQ update, useful stuff!
![]() For the EU, Gulf support. I believe GIAC is using the same flash for the whole world, but we are happy to see difference map to suit each region. I am also happy to send you logging and feedback when I get the AP for 07! ![]() |

Cobb-
Can you comment on another members post in this thread? http://www.e90post.com/forums/showpo...7&postcount=87 I was just curious myself so I did some research on the mazdaspeed3/6 forums and it would appear that Cobb did have a shaky start with that platform. One post I did find had me a little concerned if BMW's ecu had the same protocols in detecting tampering. Can you comment about the part where ecu has mileage driven/reflash? Originally Posted by*Travis@Cobb* I brought this issue up to our engineers who have intimate knowledge of internal ECU code on the*MS3/6. As far as we have ever been able to determine, there is no*flash*counter*of any kind that exists on any car we deal with. That is, the ECU does not track if it has been flashed and how many times it has been flashed. However, Subaru apparently has told their tech line to "detect reflashes" by reading the OBD-II parameter for time since/miles driven since last ECU reset. This is a standard OBD parameter. Theory being if a car comes in a few miles off a reset then likely they just returned the ECU to stock. It's a reach, but enough to scare some people. However it's not an actual*flash*counter. The only parameter that we have found that the*MS3*ECU stores is maxiumum vehicle speed, which get's reset any time the ECU is reset. Again, we have been reflashing various ECUs for many years now and this has never been conclusively proven that once the ECU is returned to stock, the dealer or the manufacturer can look at an ECU and then pinpoint a reflash has been done.* If you have warranty concerns we recommend first talking to your service manager. Often times they are willing to overlook some things. If they are not and you have other mazda dealers in your area, shop for a mod-friendly service manager. Secondly, don't leave the AccessPORT or drag slips or window chalk on or in your car, this at least will allow a friendly manager to overlook any obvious signs of unsanctioned abuse. If you don't give them a reason to suspect anything, then perhaps they won't go looking for a reason to void your warranty!* Travis COBB*Tuning Granted we are talking about a completely different platform and none of this could apply but I would still like confirmation for the peace of mind. The obvious selling point for the AP is full DIY flash capability and it being invisible to dealers. How much testing went into the n54 AP in terms of reliability and dealer diagnostic invisibility? Thanks, Alan

Looks pretty slick, great to see yet another tuning option for the N54.
Can I resale this to someone else later or is it tied to your vin, I'm assuming the AP hand held device is what Im paying for since the maps are free? Thanks,

HPF sells COBB for BMW.....wonder if thats what they are using (or going to use) to tune their Single Turbo kit with?

Why couldn't an N55 get a custom tune at a local tuner?
Just because Cobb hasn't issued an OTS map, couldn't a local tuner still dyno-tune an N55 with ATP? Or is it beause the ATP is also platform specific? |

Now that we have a couple of dynos posted up (impressive!) can you post up logs of cars running the OTS map? I'm sure everyone here will be very interested in see some type of logging from this flash to get a better idea of 1) how logging works with the AP and 2) how happy is the motor running your flash.
Thanks, Alan

I'm very curious about this. I'd also like to know if there will be a way to use the tool to make programming changes (hacks) such as the euro blinkers, or turning off bulb out warning check. I know there was a thread about this recently where some members were buying a ~100$ OBD-II tool and using software to make these changes. This is the thread for reference http://www.e90post.com/forums/showthread.php?t=451145 I know this isn't what the tool is meant for but it should be trivial compared to flashing the ECU and a nice feature if possible.

edit - I think the reason that it can't do it is not because the featureset is trivial vs not - the problem is the OBDII cable is designed to target various modules (CAS, KOMBI, IHKA etc.) - logic that would normally be absent from a device like the AccessPort (also, don't forget that the AccessPort is generic across car brands - Mini, BMW etc, I bet the unit is the same). Just my 2 cents on it.

I surly can comment. The car has a mileage since last DTC clearing. This can happen via any device clearing codes or pulling the battery power on the car, either happens often when there is an issue with a car. DTC scanners being readily available in home (AccessPORT, Procede, etc) or at your local auto parts stores (Services to scan/clear codes for free). Knowing the mileage since the last clear does not tell the dealer much of anything other than the codes were cleared or battery died XXX miles ago. Either way not much of a concern. At this point I am waiting for the BMW tech I know to scan for the AP installed and post uninstall determining if there is anything there. I will let y'all know. The Mini AP has already passed this test with flying colors, so I have no reason to believe it will be any different on the N54. Cheers, Rob |

We have the ability to keep the cat inefficiency codes from being thrown on the N54 allowing proper operation of the O2 sensors when there are no cats or aftermarket cats. Of course, no one in the US runs without legal cats, so that is for "off road" vehicles only...if you know what I mean. Cheers, Rob |

its a different ECU (hardware & software) thus needs different code to communicate and program it to work with the AP hardware, in addition to optimizing the tune (dyno time). The N55 is a huge potential market for Cobb so Im pretty sure they will tackle it after they release the remaining deliverables for the N54.
