I was gonna print off all the pages of updates for each section and take it into my dealer and see if they could do it

 

OK guys. All I know is that my mechanic told me to go to this site, enter my VIN, print out the updates and he would flash them for me. Yes the site does say Calibration hystory but it does not mean they have been flashed. It is just showing you that there are new calibrations sinse your car was manufactured. All I wanted to do was let the members know about this site so they could check it and if you want to try and get the dealer or some other GM certified shop that has Tech II to update you then go for it.

It is totally up to you to decide what you want to do. Print the info out, go talk to your dealer or who ever. If the dealer wont do it then find someone who will.

 

I just came from the dealership with a printout and they said that they usually don't do anything unless something is wrong or a customer complains about a possible issue, then they will check and see if any updates deal with that particular issue.

 

Well. I would find a private mechanic who is certified an ask them to do it.

 

The last time i used the tis2web service was to make sure my car got the right calibration when i got stage 2 . I really don't think it shows anything about new updates . When you see a NEW calibration on your Cal history , it's telling you that it has been flashed to a new calibration already.

When i checked mine yesterday , it hasn't changed at all from the print out i did last fall after i got the stage updates .

 

Yes it is a list of all the current updates but that does not mean that they were flashed to your car. Again I state do what you want with the information. no one is forcing any one to do anything. It is up to the individual to do what he or she wants with this info.

 

if you want to know how much your speedo will be thrown off go to
http://www.miata.net/garage/tirecalcold.html, also if you need any information about your VIN or VIN RPO's email me @ calculating_infinity_@hotmail.com, i work for a chev dealer and can get information off your vin for you

 

Basically it shows what SHOULD be in your car for a calibration, (including a Stage cal if purchased and installed correctly from dealer) NOT neccessarily what's actually IN your car.
You WILL loose any custom tuning if you get an update at the dealer, but anyone that knows how to use HPT will be able to reapply their various aspects of their tune to the newer calibration

PS> This IS a repost from a couple years back, but NO IDEA where it is...

 

Thanks Wop for the clerification on this matter. That is exactly what I was trying to explain to everyone.

 

can i assume these updates wont change the GM stage 2 settings? im thinking they shouldnt since the stage 2 code is listed under the VIN...

but i am goin in wednesday to get the updates. hope this does some good...

 

It should not change the stage two flash. It will only up date it. Wop was talking about if you have a after market tune in your car which I stated earlier it would be in your best interest to have that tune saved to a computer before you have the up-dates done because it will/may be reflashed back to the original stage two tune at the dealership.

good luck

 

so i am gonna print my list and bring it in

 

is there one big list i can just print... or do i have to do each and every one..





What it you click "Complete History" Does that mean it was done to my car already?

 

No, the complete history just shows the revisions that have occured since SOP (Start Of Production) Your existing calibration would likely be somewhere in that list.
and printing out the calibration numbers really isnt neccessary and just a waste of your time.

The dealer techs cannot pick and choose the calibrations they install or anything like that. In general all they can do is flash your with the most up-to-date available calibration and that is all. So they cant technically even give you the "wrong" calibration or anything. (as long as they use the correct VIN for your car that is)

Plus, once they reflash it they cant even go back to the old calibration (without contacting GM Techline, and there must be adequate justification)

Besides unless you have access to a TECH2 or some other programming tool you couldnt even confirm the correct file numbers were present aterwards anyways...

Thanks Wop. I was aware that the list of revisions was from the production date but was not aware that the techs could not pick and choose them. I appreciate you straightening us out about this. I was under the impression that a tech could pick and choose.

again thanks for chiming in. +rep

 

well mine was reflashed today,random cylinder misfire is now gone,woot1 best the car has run since i bought it.I made two threads today,one thanking Kasioboy and another about this thread and randomcylinder misfire.

 

AAAWWWW!!! Thanks Mike. (sheepishly turns red...blush)

 

go check out the thread about 'random cylinder misfire,this feels like a different car.

 

the mother f'ing service manager wouldnt do mine. said that he wont do any update unless the car is running poorly or there is a CEL thats such BS.
even after i gave him the print outs from the site he gave me some line about how the car might not need the updates and wouldnt run right What a ******* idiot.

 

remeber when you go there complain about a bad idle or something,this way they can.t charge you for it.

 

im pretty sure my buddies dad has a techII. how will he know what to do. i mean like does it just reflash it automatically or does he need certain codes that i dont have? or what.

 

The codes I believe are the part numbers th at are listed.

 

The link won't work for me. I receive this error:

E4214: WARNING: You have received this message for one of the following reasons:

2. Another user is using the same user id/password and has terminated your session.
3. Security violation - user does not have access to this application.

 

i got that error once. just try it again later.

 

Hey guys. Can you please clarify something for me? If this website shows the complete history and you have to enter your VIN to obtain that information, you would think that it would be the complete history of what's been done to your car right?
