Message:
My 1993 Dak came new with PCM # 56027850.I have checked The on line parts catalogs of Auto Zone
and Autoparts Giant as well as the dealer.the correct one is part # 56027851.The 7850 is for a
1993 5.2L/318 van.My truck has a 5.2L/318 engine,
46re A/T and Came with a 3.55 diff that has been upgraded to a 3.92.It has California Emissions.When I replaced it last year I replaced
it with the same that was in it a 7850.The original one went bad after 10 years.I have been told by Some folks whose knowledge I don't know about,that The PCM's 7850 & 7851 are the same and
Dodge does this to increase the price on various
parts. The truck runs OK.
Should I replace the PCM with the one called for in the catalogs.any information will be greatly appreciated.

janesy,
I got a MP performance PCM,but I use the truck to pull a 4500# travel trailer a lot and I have been
told or read somewhere that One shouldn't use a performance PCM to tow with.I did use it to tow from New Mexico to San Diego one time and I used mid-grade gas and it pulled great with no pings.

Oh, if you tow thats a little different. Not sure how true the statements dodge makes about towing with a MP unit, but at the same time you can't always hear detonation(ping)

I thought you were supposed to always use premium with the performance PCM. Is that true?
