Ideal ECM recommendation for new motor?

For all other non specifically listed ECU tuning. This would include can-bus ecu's such as powerpc copperhead tricore and siemens ecus. As well as GM, Dodge or any aftermarket controller tuning etc...

Ideal ECM recommendation for new motor?

Unread post by sydude »

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

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

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

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

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?

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

Would it be difficult to swap s197 ecm to 2003 Mustang and have everything functional, except pats.
