Mopar ECU in a Turbo Ford. . .questions for the pros

Well I think I am gonna do it. . . swap a Mopar ECU in my 87 Merkur Xr4ti with a 2.3 turbo running 19PSI. I am gonna pull a wiring harness from an 86 2.2Turbo Daytona for this swap and I think I will use the same computer. What are the things I can pull out of this wiring harness to help keep it simple? what is the does the Rev limiter on this puter pull fuel or spark? I will be running a Holley Strip Anniolater with it. I shoulnt have to change my coils should I? because I have a nice coil as is. what all censors does this ECU need to run right? And what would someone suggest for the best ECU for this setup. Should I use a 5th injector? I will be running some nitrous and a few other go fast goodies to, so I am TRYING to do this right. Thanks for the help in advance.
I can also be found on TurboFord.org as Mr__Merkur and email is Krazie_k15@hotmail.com

Why? The Ford ecu is fully programmable as well....only requires an adapter to fit the rear port, costs about $65.

If you really wanna swap, use the GM speed density computer from a turbo sunbird or Quad 4 Grand am..... WAAAAY superior to the outdated mopar stuff

Better off finding a 88-89 SMEC car as a donor, the 86 electronics are limted.

> what is the does the Rev limiter on this puter pull fuel or spark?

6640 from the factory, but that can be altered.

> I will be running a Holley Strip Anniolater with it.

No need, the factory mopar electronics and coil is good to over 300 hp without breaking a sweat.

> what all censors does this ECU need to run right?

All of them.

> And what would someone suggest for the best ECU for this setup.

See above.

> Should I use a 5th injector?

Only if you plan on just running a 2 bar setup which is limted to 14.5 psi of fueling.

Ford EEC IV SUCKS, simple as that. we have a Vain Air Meter witch is a big restriction and I NEED it with the EEC 4. The Mopar ECU with Speed density is MUCHO supurior to what I have. The Mopar swap is also a lot simpler to with the least amout of modifications and it has been done and proven to work well, just I wanted to get info from the people who play with it the most. I know this is proven to work to and after reading Dempsys and Guss' pages . . . well yea you get the point

I have a friend with a turbo Mustang that spent a fortune trying to get the Ford electronics to play ball, he got rid of the car and purchased 3 turbo Chryslers.

Works well enough that I have been approched by a local Mustang club that wants me to do a custom 3 bar cal for the drivetrain package.

the ignition box has two step ect. so I am not going to get rid of it unless its an upgrade. And for the books this is turning out to be well over 300HP.


EDIT SMEC car as a donor? What cars did it come in? what does SMEC mean?

3 bar cal? Mopar has always been father ahead of ford with its Turbo computers, because it does it the RIGHT WAY. . . speed density. simple as that I can continue to list on why Mopar ECU is better than Ford, but I think most of you people know, so I wont waiste the time.

Single Module Engine Controller

1988-1989 Turbo I or TII cars are the best places to look, the TII would be best since it has the charge air sensor and wiring already but you can always wire them to add them to a TI harness.

From a hardware point of view the computers are the same, just the calibration is different.

Well mass air flow meters do have their advantages, but a nice setup speed/density system is tough to beat.

sry, I'm not up to par on my T/Ds, what car/van heh Should I look to get the wiring harness out of?

EDIT when you have 2 different VAMs to work with and both are restrictive for my application, this is the BEST setup I can do without springing for an EEC tuner with Harness ect. and do you have an Instant messager that we can talk this over with? thanks again for helping and not trying to discourage me.

You should look into any '88-'89 turbo Chrysler for SMEC electronics. Doesn't matter if it's 2.2 or 2.5, but 2.2 TurboII would be best because of the additional charge temp sensor.

I would go with SMEC if I were you, because the SMEC wiring harness is much less bulky than the earlier logic module/power module ('84-'87) harness. It will be easier to fit into your car.

> sry, I'm not up to par on my T/Ds, what car/van heh Should I look to get the wiring harness out of?

Any 88-89 2.2/2.5 turbo car or van.

Ok, thanks for the help. I'll look into getting one of those harnesses. So how easy are these computers to modify, and does anyone see anything I may be over looking? I will pull the Computer, Harness(the whole thing), Throttle body with sensors, about everything. What censors are known to go bad that I should replace right away to make sure I'm working with good electrics here. What might be "tricky" while removing the harness that I may forget? I have worked with TurboDodges verry little, but have done lots of research on them. I am just trying to get everyones imput, because I know you people don't come across this everyday, but I would think it would give you that warm fuzzy feeling inside knowing that someone who loves verry different kind of car and wanting to use something great that is so common to you haha. But yea, I have a custom distributer lined up ect. BTW what size T/B is on the T/D? And what would be a good upgrade for the one I'll be using, I know I can search, but I figured while I was on the subject:big grin:

I am sorry I do not have the site name but there is someone out there that has completed the swap and posted info on the board. I printed the info out at home so I will try to post the link or at least the site for your reference.
