ready to swap in the monster 5.9
iight guys so iv'e got everything to remove this little pony 3.9 magnum and put in a monster 5.9.
the engine is commnig in 2 weeks , come complete with flex plate , pcm , and harness. already paid and everything.
my truck is : 99 dakota sport v6 3.9L magnum auto 2wd.
engine from : 01 dakota r/t v8 5.9L magnum auto 2wd.
i'm using my 42RE... for now.............
what am i better with ? my v6 ecu or the v8 one ? ( 1999 v6 and 2001 v8 PCM )
also will my cluster work or i'm better buy a 01 one ?
for sure i'm not gonna play with wires under the dash... it's pita in case i have electrical problem and i fixed it for good because of that ( removed connector and soldered wire by wire ). so ill do it next to the pcm with loom and heatshrink.
i did read the amazing red9535 thread for the swap but i'm not sure... the seller said i'm way better with the pcm that come with , but some other says keep v6 ecu...
TIME is not a factor. i can take a month or two to wire it.

alright thanks. ill wire my v6 pcm for now and later get a 99 v8 pcm.
can you tell me why they say i NEED a pcm the same year as my truck even on a newer v8 engine ?
i guess its for the ccd - pci bus thing but maybe there another reason... like maybe just way faster and easier..
when the engine arrive ill remove snow and ice to get the truck out ( stored for winter , the good old way )

even a friend with a swapped 318 told me all he did was add 4 wires for 2 injectors and extend a sensor wire.

No, you'll have to have it reflashed. Even at that, not all V6 PCM's came with the pins for injector 7 & 8 populated/connected internally.
#7
ok. because FSM have injector driver pins and wiring pinout for all engine , for 98 durango and 2000 dak and ive read another thread somewhere the dude says it can be done it just dont run perfect ( without reflash ) as a temp solution waiting to find a PCM.
if i can find the thread ill post it
2000 dak
98 durango
if i can find the thread ill post it
2000 dak
98 durango

NEWS !
i got the engine yesterday. very clean.
it came with the 01 ram ecu but i knew this wouldnt work so i told him to keep it and saved 50$.
i tried my v6 pcm , nothing
i looked everywhere for a 99 5.9 pcm with no luck. i found one at "car-part" but the seller wont ship.
all i can get is 98 and 2000 5.9 pcm or 99 5.2 pcm.
i know 5.2 will work " fine " but not at 100% of its power. but how much ? wount it run WAY too lean ?
i know a lean condition of say 15.7:1 isnt that bad unless you are forced induction but stock is ok. not the best but still fine.
in just 3 calls i could buy about 20 used 99 5.2 PCM. they are everywhere. and near me.
those options are out of questions because canada = scammer. even shipping outside canada is a scam. ( quoted 940$ CAD at 4 dealers for a reflash and take a month + 200$ for shipping both way )
- reflash.
- buy used online.
- shipping outside canada.
so why a 98 PCM wouldnt work if the FSM are the same 100% ? i had a 98 durango cluster in my dak so this isnt the problem as it was working.
