On another thread a letter from GM was posted which discusses tuning and warranty, this letter mentioned GM service bulletins 08-06-04-033 and outlines procedures to identify the presence of non-GM aftermarket calibrations.
So, out of curiosity I did a search for the bulletin, unfortunately it didn’t provide as much info as I hoped with respect to vehicle mileage, flash counting, etc... The disturbing aspect of this is that it takes the warranty issue out of the individual dealers hands, even the district service managers hands for that matter. Anyway here it is for those interested; Quote:

the mileage is partially stored in the ECM for the OLMS. if it wasnt, then when you pulled the battery, you would lose your readings for the OLMS. once again, it comes down to a warranty issue, IE driving OVER the OLMS "change oil" for 5,000 miles then resetting it after a change as if you did it when you were supposed to. While its what we call a "coarse" odometer value (a value used purely for calculations and not as accurate as the "fine" odo display on the IPC) it IS an Odometer none the less that HAS been used in warranty disputes for customer neglect. the ECM retains the oil life reading (and the coarse odometer) even if you swap it into a vehicle with MORE miles on it. How would this "theory" work since the same ECM is used in the G6 (08+ 3.5L) where the odometer is stored in the BCM not the IPC....

hmmmm.... but here I thought you guys said that there was no mileage kept in the ECM... Quote:
you guys need to talk to each other before you go counter-posting each other speaking of which, have you verified your tune's "stealth" ability yet? its been a little more than the 7-10 days you originally gave us for the time frame.

What people wanted to know is if there was a hard mileage log in the ECM, there is not. The point is mute anyway since all of our Camaro tunes have been PowerFlash tunes, except for the Chevy dealers that own our remote shop cables. As far as the Stealth feature goes, the CVN numbers always match with our calibration installed. Again, the point is mute since all tunes are PowerFlash tunes. Of all of the Camaro tunes we have sold, not one of our customers have been even slightly confused or cared about this. It only seems like people with no interest in getting a tune keep bringing it up. That being said, in the well over 1000 remote tunes we have done we have yet to see a single warranty issue. Over 435 of these are G8 tunes (same ECM). |

Just because you dont consider the OLMS an actual mileage counter does not mean that GM does not as well.

The Oil Life system does not run off mileage.
It is on page 9-13 of the Manual: Engine Oil Life System When to Change Engine Oil This vehicle has a computer system that indicates when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change is indicated can vary considerably. For the oil life system to work properly, the system must be reset every time the oil is changed. When the system has calculated that oil life has been diminished, it indicates that an oil change is necessary. A CHANGE ENGINE OIL SOON message comes on. See Engine Oil Messages on page 4-32. Change the oil as soon as possible within the next 1 000 km (600 miles). It is possible that, if driving under the best conditions, the oil life system might not indicate that an oil change is necessary for over a year. However, the engine oil and filter must be changed at least once a year and at this time the system must be reset. Your dealer/ retailer has trained service people who will perform this work using genuine parts and reset the system. It is also important to check the oil regularly and keep it at the proper level. If the system is ever reset accidentally, the oil must be changed at 5 000 km (3,000 miles) since the last oil change. Remember to reset the oil life system whenever the oil is changed. |

So if the ECM is disconnected or the OLS is reset before the oil change, the system won't be working properly.

Kirk - Out of curiosity if someone were to have one of your tunes and the factory declined warranty coverage based on the tune not matching the factory tune would you be willing to cover the cost of repairs?
