Please forgive my ignorance, but what does the mopar performance pcm do for you? I know nothing about these.

 

Back when certain vehicles where new Mopar performance or Direct connection as they where known back then offered performance pcm's. They where only available for something like 5-10 years after the vehicle came out so now they are hard to come by.

 

It's just an out of the box performance tune. They give you a bit more power by adjusting ignition timing, probably adjust the fuel trim to make the mixture a little more rich at times, and increase the rev limiter.

Extra power is nice for anyone, although the 92 octane fuel requirement would hurt a bit. For me one of the main attractions is increasing the rev limiter. My car is a solid 1200 lbs lighter than the 2nd gen trucks, plus I have the M1 intake, headers, and a small cam. The car wants to keep pulling way past the 5200 rpm limiter the stock PCM provides.

 

They brought Direct Connection back! I think it is pretty neat

 

Ugh... $100. If only I had known that years later I would have a 95 5.9 Magnum! And like @HeyYou said, i shudder to think of how many ended up in scrap yards.

 

I guess my question is, what advantages does the high performance pcm offer over the standard pcm.

 

More power. Its basically the equivalent of installing a performance tune on an OBDII vehicle.... OBDII is just easier.

 

I have one. Do you still need it?

 

No, I found one.

 

You might want to post that for sale.
