i think there should be a way to just reflash the part of the memory that stores the vin and other two numbers. or maybe this information can be input upon initial flash.
Also do we have any other verification this has not affected 2004 WRXs?

the title of the thread is:
2005 ECU OBD Requirements - Hurdles to Reflashing so this problem only applies to reflashing the ECU correct? what about if I were to install a Xede or UTEC??? |

They're both piggie backs and should not cause any problems. The UTEC I know does not. The Xede should not be a problem either. The only problem that they can cause is failure of the emission test itself.

I imagine that Cobb will likely take the same stance that EcuTeK has. I wouldn’t think that anybody will want to invite the wrath of the government by producing a product that deliberately defeats a requirement of an emissions test. The only question will be if they will develop it so it can be divorced cleanly without leaving a footprint. That way you can uninstall it yourself and have your car tested. Their product would not directly be the cause of the pass of the test. This would be the win-win for everybody. Hopefully EcuTeK will also have it so you can restore factory settings with a low cost reflash. If they choose not to produce it so the default can be restored they will both loose many customers and we will loose a couple of good options for EM.

I think Cobb and vishnu and all others that offer a reflash should be able to put these in without prolems from the Gov. At leaset it should be possible for them to get permission for putting it back to stock. The the WRXhackers forum my be able to do more. Either way if reflashed to stock does not include this info you will be stuck either way with a failure notice at the inspection station. I hope every one has friends in "certain" places until this gets fixed. |

As for a mechanism to make the VIN, CIN and CVN pass at an emission testing station, what purpose would that have? You could not really claim that it’s for off road use only since its only purpose is to subvert a regulation. Now if the producers of such a product were to consciously add a mechanism that purposely defeated a government test that might create a less that desirable legal situation for such manufacturer if certain regulating bodies were to catch wind of this. |

I guess I can see the logic both ways but I'm not sure it's such a stretch from one to the other.

lets find a solution(s)
does a piggy back like the utec avoid this vin altercation problem? if so, then i will go this route (although i would rather take her in for a ecutek reflash since i have little time to learn about utec and other more dangerous self-tunning options). can you purchase an 04 ecu that will work 100% with an 05 subaru, like the baja or fxt so you can reflash that and save your 05 ecu for testing and warranty purposes? it is obvious now that ecutek and accessport will lose alot of money unless they do some sneaky business practices that will include finding a way to preserve the vin # and can still apply the "off-road use only" method. |

OK, I've been getting a few emails and phone calls about this issue....so I thought I would let you know that we are aware of this issue and we will be working on it.
I will let Trey go into more detail about how the AccessPort will handle this when he has the time, but needless to say, the AccessPort will support the VIN number request. We will most likely roll out the 05 AccessPorts first, and then post a software update on our website at a later time, but well before anyone has to take their car in for testing.

Thanks Cobb. I knew you guys would come though. Now off to get my AP.

Does anyone know the ECU calibration ID (CID) reported by a 2004 STi ECU after it has been reflashed with a Cobb Accessport? ibis?

Trey Cobb posted yesterday on LegacyGT.com that the CIN/CVN values were already "supported" in the '04 STi and FXT. Thread is here, posts #97, 101 are of most interest.

I swear that I posted this question before, but I don't see it now.
Justin, You guys are saying that CVN (calibration verification number) is supported. Does that mean that an ECU w/ an AP will send back a false CVN number showing that the ECU software/ROM has NOT been modified? It seems to me that it's one thing to support CVN, but it's something different to calculate the correct number for your car and pass a smog check. I was under the impression that this statement: "(4.7.1) All 2005 and subsequent model year vehicles shall use an algorithm to calculate a calibration verification number (CVN) that verifies the on-board computer software integrity" meant that the CVN number would change if the software on the ECU was changed. If that could be cleared up for me that would be great. Maybe I'm just misunderstanding the whole CVN thing. |

The AccessPort has always performed CIN and CVN functions since previous ECU's already did this. The only thing that is new is the VIN function, which is an easy fix. I wish I could easily explain how these functions actually performed, but I am currently not at liberty to say.....sorry. All I can say is, all the needed functionality will be in place shortly

I understand that the VIN function has been added. No big deal, not much of a concern as far as I can tell. VIN is a piec of cake, CVN is the one that bothers me.
I understand that the CVN function is still in place, I would not expect you to remove it as I'm sure you guys don't tuch 90% of the ROM, just the tables for fuel, timing, boost, and all the other tables that effect HP and drivability. But from what I'm getting out of the description of the CVN, if you guys did not alter the CVN algorithm then it would spit out a calculated number from the ROM tables that would be much different than the stock CVN number that the algorithm would spit out if it was calculating the tables from the stock ROM. So bottom line... if an ECU has an AP married to it, will the CVN algorithm come up w/ the same CVN if the car was stock? It doesn't seem likely to me, uless you guy alter the CVN algorithm to spit out the right number every time. |
