I am doing a hemi swap into my 79 aspen and we finally got it to fit! But now im reading that the factory computer I have can't be flashed. Is this true? Hotwire says the best thing to use would be out of a 2005 dodge ram but my hemiband computer oddly enough came out of a 2007 chrysler aspen (which is still sitting in my yard). My question is can I use this computer?
