Hi guys. I’m trying to figure out which ECM to go with for a new motor that I’m building (see signature below). My current eec is a AKC0 with a QH and I use binary editor. I’m happy with the way it runs, but for the new motor I want to go fully distributorless, preferably with individual coil packs, or at a minimum with built in EDIS(8?). A big plus would be CAN bus, for digital dash capability etc. I definitely want to stay Mass Air.
So I think I definitely want to go with something more modern than an eec-iv, but I don’t know what would be best. Here are the eec’s I’m thinking of, in the order of current preference:
1. Ford CDAN4, or any Ford ecm that would be newer and better (I know nothing about eec’s newer than eec-iv)
2. Haltech Elite 2000
3. Pro-M EFI
4. Stinger PIMPxs
My existing harness is thirty years old, I need to replace all of it anyway, so additional labor and time to change to a different wiring configuration is not an issue. Cost difference between these choices is also not a consideration.
my top factors in order:
1. Long term reliability and parts availability
2. drivability
3. Modern infrastructure compatibility and expansion capabilities
Your suggestions and advice would be hugely appreciated.
Thanks
Sy

Re: Ideal ECM recommendation for new motor?
RZASA is probably going to be your best bet. You can get an ecu and wiring harness from any 03-04 crown vic. im currently building a 57f100 and am using what I suggested. Ill wait for others to chime in but i think RZASA is going to be your best bet

Re: Ideal ECM recommendation for new motor?
I was looking to go distributorless and individual coil on a windsor as well. I pulled an ecm, engine harness and crank sensor from a 2004 Mercury Grand Marquis and planned on using Rzasa but have not started the install yet

Re: Ideal ECM recommendation for new motor?
None of the eec's are going to be can bus thats powerpc and newer 2005+
best bet is always a 2004 luxury sedan ecu as whats been said running an rzasa tune

Re: Ideal ECM recommendation for new motor?
What’s the best place/way to get an RZASA ecm? A rebuilder like Cardone, Flagship One, etc? They all ask for a VIN and mileage, which I assume doesn’t matter if I’m ‘tuning’ it. I can’t seem to find any private party used units, and I’m wary of buying a unit from a junk yard remotely (there aren’t any local yards near me)
How about PATS? Is that anything I need to pay attention to I’m picking an ECM? Or is PATS simply disabled in the tune whether the ECM has it built in or not?

Re: Ideal ECM recommendation for new motor?
Always best to get them from a u pull it.
We don't concern ourselves with PATS.
I can ship you an ecu for $150 if your interested. LMK your full setup so I can flash a base file to it. http://www.efidynotuning.com/info.php

Re: Ideal ECM recommendation for new motor?
Would it be difficult to swap s197 ecm to 2003 Mustang and have everything functional, except pats.
