I just swapped in an 0411 pcm out of an 02 Silverado into my 98 camaro after the factory pcm fried upon flashing the 2 bar speed density tune into it. I repinned the harness for the new pcm but my main question is if theres anything special I need to do before licensing and tuning the new pcm. Id hate to loose more credits as ive already wasted 4 on the 98 pcm when it fried.
