Hey Guys. 2020 Challenger new modded PCM. Is it plug and play or does it need to be programmed also

any 18+ pcm replacement requires that you read the skim from the stock/original pcm first then load that to the replacement pcm before it will function in the vehicle properly.

So if tech installed installed without previously doing that and then follows the procedures. should it function then? I put the old PCM back in read the old one. Then installed new one wrote tune to it. Now no crank issue. Has skim code

Hey Mike tried it again by putting the old PCM in the vehicle and then reading it and then reinstalling New Modded PCM in it. Installing Diablo canned tune and once again Skim code. \Called Chrysler to get Pin # so I could do it through J1234 tool, BUT since I don't have a Chrysler invoice for it. They will not give it to us. Guess they are starting to get a bit tight on giving them out. Whats next?

something is missing, give the support team a call and they'll get it sorted out.
