Stock computer need to change or not?

When buying the same block displacement (302ci) and aftermarket block, do I need to get a modified computer or do you use the stock one for the efi. Ive never thought to ask this question before. Anyone got any idea?

Also want to run a P.S.M

1994-95 Mustang Series 4 Pms (Programmable Engine Management System), 5.0L & 5.8L

No you do not need a modified computer.
The stock EEC-IV ECU will serve on most 5.0 (302) & 5.8 (351W) engines.

It is only when you step far outside the norm with forced induction, nitrous oxide injection, large cubic inch or high compression/high RPM applications that you may need to be able to modify the parameters outside the limits of the stock ECU.

The EFI-Systems Series 4 PMS for the 94-95 5.0 Mustang is a good choice and here is why.

And Here’s why.

. Plug n play. No wiring needed

. View screen on key pad monitoring spark timing, rpm, injector function, throttle position, load range, water temp, air charge temp, manifold pressure, mass air voltage.

. Full tuning ability through Key pad (no lap top needed)

. Full sequential stand alone.

. Real time tuning. While engine is running.

. No waiting for flashing or uploading.

. Tuning from idle to 9900 rpm in fuel and timing in 500 rpm increments

. Tuning by boost. Up to 30lb with 3 bar map sensor

. Tuning for Nitrous.

. Tuning by air charge temp or water temp for fuel and timing

. Individual cylinder tuning for both fuel and timing

. Start fuel setting which controls the injectors when the starter is turning the engine over. This gets ride of the hard starting with 42lb injectors or bigger

. Two step rev-limiter

. Two programmable output switches by RPM/TPS

. Stores three separate tuning programs

. 100% more powerful with twin processors than FORD ECC computer

What about forced induction for example a turbo. What would I need to do in the computer aspect of things?

Since you will be moving a lot more air and using larger injectors than were ever intended, a PMS, Chip or Professional tune will be required to help your factory computer compensate for the changes and tune your engine correctly.

What company makes computers for forced induction? Also will want to run a PMS but would like to get a new computer as well.

There are lots of specialty manufacturers out there with all types of EFI computer systems, but they are expensive. You're probably looking at $2500 and up for a specialized system.


Your stock computer will work fine with the PMS.
The PMS piggy backs on to the stock ECU and is able to take complete control of the system if you wish it to do so.


For an automatic 94-95 car (never can remember what everyone has) I would also add a Baumannator Transmission control for better control over the AODE transmission.

What's a beff tranny?
When you have time, maybe put your car, specs and mods in your signature?
It would sure help me when you ask any questions.


P.S. I also put up a picture and question in your profile.

Lol I meant to say a "beefy" tranny haha auto correct and I'm on my phone. I'll update my specs.

Also I remember you saying on
Someone else's post about some people that make some strong manual transmissions. What where they again? Handling around 800 torque. I remember you saying they were expensive.

I thought you might have stumbled across a transmission I hadn't heard of before.


Let's see....G-Force, Jericho, Lenco,.....and others I can't remember now.
I think G-Force can pretty much build anything you want.

Use the 5.0 and keep them guessing.
There should be a reply button or view conversation.
