i don't know, but if you just go to the dealership and take your registration in, they can look up all of the security codes for you.
you need to download it.Good to know, I got the codes yesterday after I got the run around from several dealers. No one thing I don't understand does the Tech 2 have the stock tune saved in it or do I need to download it from somewhere?
do you remember my post in the other thread about getting an ACDelco TDS subscription and the TIS2000 software?Do you know where to get it from?
i have a sneaking suspicion that if you did have a key code lookup done, you did get the code, it just wasn't called the "IMMO" code on the printout.Could you or someone else use your software and connections to look up my IMMO? That's the only important piece of data the dealership didn't provide me for my 04. (I have the security card for the 06.)
interesting.The only four digit codes I got were "radio PIN" and "GloveBox Code". The glovebox code was used to cut my glovebox keys. The sections left blank were VATS Code, Storage Key and IMMO Code.
guess you need to relink with the PIM no matter what on the 05/06 cars.Nope disabling VATS doesn't work tried it
i guess the simple answer is that it should rewrite the OS as well as the calibration, but there's more data in the ECM than those things. you can't flash a blank ECM with HPTuners, for instance. you can with GM SPS.What does a complete write do with hp tuners?
