Hi Guys,
I just installed my new overkilled pcm and I am wondering if i need a case re learn.
The thing is, my engine light was on before the install and is still on so I can't tell if I need a case re learn done. I had the check engine light looked at by the dealer years ago i forgot what it was something stupid like the exhaust sensor not worth fixing they said.
The car started and runs nice. At first it said wouldn't start due to security..but the second turn it worked great and hasn't given me that warning again after many times.
Now I also would like to know if the tune works before you get a case relearn or do you need a relearn to activate the tune or to make it run better or something???
Sorry if i seem like a noob when it comes to tuning I have no experience with this that is why i got a pre tuned pcm
Thanks!
