Mass-Flo systems

[Merv and Sharon]

Many thanks Peter. Appreciated. I will talk with Michael in the new year. Have a great Christmas!

Note the comment about being able to run on an EEC4 but what about the AU EEC5 computer?

Can the later model computer be tweaked as well to suit this system?

Cheers

Mine is an A9L is that 4 or 3 EEC?

[TUF-427]

A9L is the 88-93 Mustang Manual ecu EEC4,
and the best one to have imho,
for tunability and acceptance to adaptive tune to engine modifications.
so your set there Merv.

Steve,
EEC5 starts to get a bit harder and once you get into Aussie Smartlock Ecus its sometimes best to retrofit the earlier Ecus ,as we have done in Ash Brights car.
Eb and ED pre smartlocks are essentially the same as their american cousins tho..

As far as your EEC5 AU Management it is very different,
running coilpacks,crank trigger and no distributor etc,wiring is different too,
in this instance your probably best to buy a full kit,
Retrofit then sell off all the Aussie specific stuff you dont need...

This will really depend on how good the Mass Flow Airmeter is calibrated to mimic the Ford factory original,

If they could guarantee their calibrations are the same as the AU meter I dont see why it couldnt work,

though the Ecu programming is far more complex in the later generation Ecus making them less forgiving,

even throttlebody airflow etc is taken into account in the programming which will be different with Massflo

[stephen low]

My EEC5 has the smart lock turned off care of one of the guys that helped develop the system so not an issue to overcome.

However I don't know how this affects the other operations in the system and I can only assume this makes it easier to play with if and when the time comes.

Have a good Christmas All!

I am going to call the Mass-Flo guys after New Year and have a chat. I have a new Summit distributor that I can still use but I seem to need a new manifold as well, altho the existing one could be retained, it seems from Peter's comments. The heads web site that you posted Mike looks a beauty. I should see if they have any for the 302.

Hey Merv you may have misunderstood my previous posts a little,

I meant retaining all the electronic and wiring side of things as you already have whats required,

and just getting what Wrench87 has just described off massflo,

Modified Carb style Intake with injector bosses and fuel rails,

the Massflo throttlebody and MAF,and the Massflo harness/convertor adaptor .

Having a chat with the Massflo guys is a great idea,
tell them exactly what you already have and what you want to achieve and im sure they will suggest the best option..

Personally for me its gotta be 8 throttlebodies!

I like your thinking Peter

Cheers

[wrench87]

thats the one, the one thing you must know is this type system is speed density and does not use a mass air meter. depending on what engine management system you use you can get rid of your distributor and use a oil pump drive and coil packs. i have the mass flo on my 342 and it runs great, but you cant beat the looks of the 4 two barrell systems.
i think profesional products makes a system also that comes with a controller that is self learning with a single wide band 02 it has the 4x2 t bodies i think it is under retrotek?.

[wrench87]

the other 2 options are the fast ez efi, and the powerjection III. you should also check them out easy to install especially if you already have a efi pump and a return stlye fuel regulator, once again they are speed density but they use a wide band 02sensor and are self learning.

[Merv and Sharon]

Great - thanks again Peter!

Do Mass-Flo do 8 throttle body systems!

[wrench87]

mass flo only makes the 4bbl t body set up, if you go to the ffrcobra forum and look under advertisers you will find a company called very cool parts they have the least expensive 4x2 set up.

[Merv and Sharon]

This one Wrench?

I think it looks absolutely fantastic, but not sure how difficult the change to speed density would be. May be i should stay with the mass air system as that is what I have?

Merv

[TUF-427]

Believe it or not they are the Aussie DC+O intakes the same as I am running,
but yes to do that sort of change requires Aftermarket ECU,Distributor etc,
Unless you want to put it in a plenum which defeats the purpose!

Merv,Stick with the massflo unless your willing to spend upwards of 10K!

[Merv and Sharon]

It is a toss up. For that I could buy a whole crate motor from Ford racing with most of the good bits on it! I would like to get rid of that ugly plenum however ...

[Merv and Sharon]

Thanks again Wrench - I am starting to get confused again.

I have a stock standard Mustang ('92) 5.0L HO EFI set up. The car has enough power in standard form and getting the power down is the fun part. Too much power would spoil the everyday driveability of the car in my opinion. I am not interested in tire burning or bragging rights.

However: (1) I am keen to get a 'carb - look' with probably a 4 throttle body intake. I am also wanting to use as much of my standard EFI set up as possible;

(2) I am considering some moderate top end refurbishment with ally heads, roller rockers and probably new induction manifold, as needed.

The more that these 2 new systems cost, the more it tips the overall balance towards a full crate motor from Ford Racing or elsewhere (some where around 350hp so as not to mean a gear box change)!

So these Fast Ez Efi, and the Powerjection III setups look fantastic but they are all speed density as you say and that seems more difficult to establish. I guess I am looking for advice on how to either modify my standard motor to achieve these two objectives - whether I should give up and go the crate donk!

Merv,

any crate motor still only gets you half the way there,

As their only really a long motor package for a windsor,

im not aware of a complete EFI style package,

maybe not from ford racing at least..

you still need to do the induction and fuel side on top of a crate engine anyways,

What you currently have now if yours is an 88-93 style mustang motor will be too small and restrictive for the 300-350 fwhp.

Intake,throttlebody,Maf,Injectors,Ecu Chip maybe even your current fuel pump all needs attention for that sort of power delivery..

If you want the Carby look,

You really cant go past the massflo intake setup with your choice of alloy heads and a mild cam you wont be dissapointed..

and all the benefits of a self tuning Mass air Management system...

Dont forget for the power this will make will require at least 24lb injectors and a chip..

Peter..
