I know This is an old post but I'm curious if y'all know anything about the sct eliminator 4 bank e prom. I'm used to tuning obd2 vehicles and have never messed with an obd1 so I'm at a loss on what to use to get some more power out the truck. It's a 95 f150 5.0maf 4x4 currently an automatic, I have longtubes on it and will soon be putting a cam and gt40 heads on.

It's really no different than a regular chip, only you get 4 tunes instead of 1...
What do you need to know?
The chip has nothing to do with power, it's the tune itself.
Programming a chip is no different than flashing an ecu, you still need to Dyno tune it for max potential. Don't get a mail order tune. Go to a local Dyno tuner and get it done right.

So can I just take it to a dyno shop and they can flas the eec on the truck? I don't give a damn bout going back to the factory tune so if I can save the 250 it costs I'd be real happy lol. I don't need to swap tunes, I want an all out performance tune to run all the time
If you don't have an obd2 truck, you need a chip
They make a single tune ship, and a multiple tune chip. Go to your Dyno and see what they can program. They may be an sct or possibly a diablo chip seller, they may not offer a switch chip, so you're only getting one tune anyway.
Call or go to your Dyno shop with your ecu code, and see if they offer a chip and can program it. That's the easiest way to move forward with this.

I said programming a chip is no different than flashing the ecu... I did not say you didn't need the chip.

The way we did it in the GM world was to use a 2-bar or 3-bar map sensor and rescale the tables accordingly.
This of course reduced the accuracy of the data tables because the sensor now covered more range vaccum to 2bar or 2bar, instead of vaccum to ambient pressure.
Generally one could compensate that with a little nudging around idle to a point.
With Ford EEC and forced induction, are there 2-bar and 3-bar MAP sensors?

?!?

From what I have seen, the forced induction seem to have used mass air sensors. I was digging into a 1990 SC engine system, it used DIS and MAF on it's controls. Since Ford MAP sensors actually put out a frequency signal vs everyone else using voltage I'm not sure what could do.
I have a Chrysler Turbo-II engine in my Lebaron convertible, it uses a 2-bar sensor and I run 14 psi boost, if I wanted to go over that (engine will easily take 20 psi) I have to go to a GM 3-bar sensor which is, like the Chrysler one, 0-5 volt signal. Chrysler was still using a MAP sensor on the 2005 Town and Country we had.

Hello, I had to re-up(computer crash) I do lots of reading/googling, and yes this is old but I believe this is good info I am trying to share, on NLOC,net, a thread title PiMPxs (MS3)) started by Dark Lord, seems as though, stinger performance is adding a real plug & play ecm/ecu that also controls our E4OD trans, that they are intro'ing this year, stinger rep starts telling on page 9 post #127 or #128, and saying will be cheaper than megasquirt/quick 4($1,800) or another one @ ($1500) with quick 4. says theirs will be less than ($1500) and has a lightning guy as guine pig for them, working bugs out, I've tried looking at their web site, dont have a clue if I was even on right one, only seen 4cyl turbo stuff? I have 95 F150 SC 4x4 5.8L

Interesting how far some of this has come since I was working on mine. I thought at one point I was dealing in black magic trying to get any information on a MAF/SEFI 460 and E4OD. The latter was the biggest stumbling block, the Mustang EECs will work just fine with a manual or even a 4R70/75W transmission, the E4OD is different enough that it is not possible. Primary reason is the E4OD has a coast clutch that is engaged in manual 3rd to ensure engine braking. The Output Shaft Speed sensor can probably be worked around.
