soo that's means mopar pcm are more like basic level, as for vec, boomer, dc and another are more like high performance, correct?
Yes...well kind of...the pcm you get via Boomer and DC are aggressive but safe, I think they get them from the same source. The VEC III is designed to be programmable...I have five different tunes for my VEC III...for the following purposes:
"NO START" - if someone is going to steal my truck they will have to drag it off...no way to hot wire it, or even if they have the key...no start means no start!
I also have a 91 Octane tune for emergencies when 93 octane may not be available.
Then I have a tune for 93 Octane without meth injection;
A 93 octane tune with meth injection (Hot Rod)
And finally I have a Valet Tune...max rpm is 2500...
I can change the tune on the fly via a card reader in the dash.
I leave the tune on "Hot Rod" most of the time...if I park where people can get to the truck (anywhere other than my garage) I use the "No Start" card. Have never used the 91 octane card, or the Valet Tune...would not dare let a kid drive my baby....
The VEC III is a piggyback. It does not change your pcm, it just intercedes before the instructions from the pcm get to the operating part of your vehicle! You need a knowledgeable person to program the VEC III.
One advantage to the more conservative MOPAR flashed pcm is that it does not affect your warranty. As with all mopar add-ons, dealers cannot use them as a reason to void your claims. But they will raise their eyebrows a little and think that you abuse your truck...duh...
Many who have a flashed pcm (non-mopar) keep their oem pcm and put it in before going to a dealer.
Hope this helps.
