That is why we suggest using our PowerFlash system instead of swapping ECM's. Flashing the ECM will not change the oil life system values.

hmmmm....

but here I thought you guys said that there was no mileage kept in the ECM...

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.

You mean talk to myself? I made both posts. I do not consider the oil life system an actual mileage counter since the owner can zero it at any time, heck you could zero it every day if you wanted.

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).

the G8 ISNT the same ECM, its the same family, but the Camaro gets one with quite a few new revisions (one being the addition of the third medium speed data bus that the Tech 2 cant be used to read).

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?

I think it is working properly just that it calculates it since the last time it is reset. Not sure what would happen if the ECM was disconnected.

Then they go on to say....If it is accidentally reset...

Don't go there. The last thread about this went way off track and got closed.

The 2009.5 ECM is most certainly ther same ECM. I have plenty of them in running Camaro's right now. We call it a E38V2.

If GM wants to call a owner re-settable system a mileage counter, I guess that is OK. It will only show the mileage from the last user re-set.

On a side note, I just replaced a ECM in a new Camaro and didn't have to re-set the oil life, it was still correct.

The internet is a great place to disseminate information, this message board is no exception however there seems to be a lot of misinformation relative to our ECM family specifically the Camaro ECM so I’d like to take a minute to address some statements to allow a glimpse into how we program these controllers.

Does the E38 have a “flash counter”?
Both the original E38A and E38B have support for a flash “tracking system” of sorts. While it’s not as in depth as the Bosch E35 used on the LMM trucks it does exist however current production releases have it disabled, but this could change at any time. When programmed by a GM Facility the unit already stores the programming date (as sent by the programming software) as well as the programming station or repair facility ID.

OLMS/Odometer
OLMS does have an Odometer?
Yes it does, its used for a very small part of the OLMS system operation.

“OLMS is partially in the ECM”
OLMS resides in it entirety in the ECM. On this note OLMS does not read mileage from the IPC or any other module in the vehicle.

“The 2009.5 G8 ECM is the same as the Camaro”
While they both have the revisions for the new version 8 software they are most certainly not the same. The 2009.5 L76/LS3 G8 uses the 12625455 ECM for software rev 8.9 while the Camaro uses the 12633238 for the newer 8.10 software. In fact if you load a Camaro calibration into the G8 ECM it will render it unusable.

AFM actually can be controlled by the transmission status bit, this is how it’s turned off in Manual mode otherwise when the ECM saw the conditions even in manual mode to enter AFM it would. The AFM enable by trans status bit can be set in the ECM.

Thanks for helping clear this up.

“OLMS is partially in the ECM”
OLMS resides in it entirety in the ECM. On this note OLMS does not read mileage from the IPC or any other module in the vehicle.

My main point is there is no "hard" milage counter in the ECM. That is what the original question was.

“The 2009.5 G8 ECM is the same as the Camaro”
While they both have the revisions for the new version 8 software they are most certainly not the same. The 2009.5 L76/LS3 G8 uses the 12625455 ECM for software rev 8.9 while the Camaro uses the 12633238 for the newer 8.10 software. In fact if you load a Camaro calibration into the G8 ECM it will render it unusable.

I have yet to purchase a 2010 ECM I always use 2009.5 E38's. I have not had an issue running them in a 2010 Camaro. Maybe I'm just getting lucky?

You are correct here, but we can not find this as of yet. I think I know why you can.
