Jet tuning problem..
So i tried to pull the tune off my car its a 96 btw.. it failed the first few times, but then I got it to download & unlocked the vin..
Well it says its a LM4 5.3l and its a 96... and im really confused, Now it won't read the ECM again.. When i try and scan it with autotap it says it can't find the VIN..
here a pic of what i see, im a newb at tuning so bare with me..
