Hello
I am trying to find out what the program strategy revision would be for this computer.
F2TF-12A650-AHB
EFI-SD47B
This is a Z2D1 computer and I would love to know if anyone has information on the definition for this strategy. The computer is out of a 1993 f150 4x4 auto with 5.0l (I'm sure this is a 5.8l computer right from ford)

Thanks in advance

 

I have the same problem my 93 Ford 150 5.0 E4OD has the same Z2D1 and it is a ******* child. i built a 347 with a bunch a little mods and i had to run a diablo chip and dyno tune it on a chassis dyno and he had a hard time getting it to play nice and even when it was done it had some quirks then i moved to a higher altitude and the calibration is off

 

I wound up converting to a WAY1 computer and it works nice. The SD bank fire was a joke and hardly better than a carb setup.

 

wouldnt happend to havea spare WAY1 computer laying around

 

I had a hell of a time finding this one. Its got to be the last one in Canada..lol
I was told that rebuilders could burn a suitable one for you and you'll get a warranty with it too.

 

I just scored one (WAY1)out of maine should have it early next week. Now i have to start building a harness and try to get the ducting and mass air meter. Then order the Moates quarterhorse... Binary editer.....statagy file....Inivative Wide band O2 from Moates.... and a better laptop...

 

You will be more than pleased with the way1 computer.
Engine harness is pretty straight forward to do but it does help to have an old harness to rob wires and pins off of. I added a second 8 wire connector to handle the extra 6 wires for the injectors. Be careful to use pins which fit the female pins (ford uses two distinct pin sizes in their harness).
For the mass air meter, I found a 4.9L mass air meter with hose and duct which goes through to the front of the rad support in a 1995 vintage explorer pickup and everything bolted in like stock on my 1993 f150 4x4. I needed to heat and stretch the dual opening in the intake hose to install the shortened SD intake hoses on with the use of some short exhaust tubes and hose clamps.
I'm currently running a .030 5.0L with stock hyd roller cam out of the SD system and it gives me about 17.2 mpg hi-way mileage (imperial gallons) running around 1800-1900 rpm at 100 kph (64 mph). That is quite the improvement over the 13 mpg with a good tail wind i was getting before.
I am now going to try and set the injector timing and ignition advance to see if it can get closer to 20 mpg using the moates chip.

 

I'm looking forward to the gas milage improvement. my truck is running the ford explorer mass air roller camshaft, and 24lb injectors so the computer isnt going to be happy until i get the moates quarter horse so i can recal the cubes and injector size. clint garrity (Makes the Binary editor software used with the quarterhorse) said i should use something bigger than stock for the mass air meter because its going to choke off the engine. I'm not sure how many MM the stock mass air meter is but the stangs from 89-93 are like 55mm i wouldnt think the truck would be much bigger if at all. I was thinking about a vortech next......over 450 ftlbs of torque at 2000 rpms. thats getting into 2000 vintage diesel numbers that should tow the camper better.

 

The MA meter i got is somewhere in the neighborhood of 73mm and that is off an EEC-V truck with a 6 cylinder (4.9L which should have the same basic airflow voltages as a 5.0L). These meters are fairly standard and used on a variety of different engines according to part numbers I've seen for replacements. The calibration is probably off a bit for the WAY1 computer but it actually runs pretty darn good on the stock tune.
One thing I would like to change is the ignition advance as they retarded the cures around the shift points to give a soft shift and slip the clutches. The other thing would be to lower the cold start IAC rpm a little. I also should adjust the injector size up a little from the 19.24 lb to about 19.4 lb as my pressure is a little higher than the 39 psi these are rated at. Small potatoes really.
I have a friend whom I picked his brains a bit over this who has the same basic setup except he has Roushe heads on a 5.8L with e4od 4x4. He used a lightning mass air meter (95mm I think) and filter box with his and has had good luck with his set-up.

One word of caution is that the transmission valve body and harness were changed somewhere around the 1995 year on these trucks. The harness has a diode in the updated harness and I think the older computers had the diode in the ECC. My transmission works good and its a 1993 e4od so this might be an old wives tale.

 

clint recommended the 90mm lightning from ford racing. Seems a little overkill for a normally aspirated engine small block.

 

Yes, I think its a bit much for a naturally aspirated 5.0L engine but I thought i read something earlier about a blower? They pump a lot of air through an engine. It really depends on what you intend to do and how all the components work together. Nothing generates dependable torque like a long stroke engine, but you do burn more fuel generation that torque. The vortex idea would increase combustion pressures in the cylinder but it achieves that by increasing the volume of air and volumetric efficiency of the engine. You'll burn more fuel to go the same distance just by trying to keep a 14.7 fuel/air ratio in that larger volume of air. The stock p/u, ecololine and Lincoln meters were 73mm I believe, and that is just slightly less than the area of the stock throttle blades in the SD trucks

 

the 73mm seems big. the mustangs were runnning 55mm why would they run bigger mass airmeters on a truck or a lincoln?? If that was the case the mustANG guys would have been stealing the mass air meters off the trucks, but i have been wrong before.

 

I think if you search the 5.0 HO meters you'll find they are 73mm meters

 

86 87-93 5.0 MUSTANG 55MM MASS AIR METER or conversion:eBay Motors (item 320444855320 end time Dec-04-09 15:05:58 PST)


This is a stocker 5.0HO for sale on ebay. They have a good shot down the bore and u can see its not that big. The sample tube is part of the casting.
It seems in the early 90s for must have figured out that they were choking offf the engine. the cobras from 93 were runnning 70mm with 24lb injectors

This is what I have installed on my truck. They show a list of what vehicles use the same meter. It is mounted on the filter box, has a single tube which splits into two tubes for the throttle body. ?You are best to get the whole thing, brackets, tubes and wires out of the junk yard. Ford started about 1995 putting maf in the trucks.

This is basically what it looks like. Use the temperature sensor located in the filter box instead of the one in the intake manifold. The meter needs to know the air temp its metering, not the air temp of the mass in the manifold.
