Just plug and go, or did you have to reprogram?

 

I didn't have to reprogram. Thought I would do that latter. I'm going to go with a 520 in the future.
The fuel curves are good to go with the GT computer. You'll continue to get the Check Engine light, but that will probably be for the EGR. You can check your codes.

 

Is the A9P capable of supporting the E4OD?

 

I'm not familiar with the autos. If this is the stock trans that came with the truck, it is suppose to be good to go.

 

It will only support it with lots of work, and then, not very well. A9P would be a really poor choice.

If you're staying with EEC-IV, you want a VEX1 or WAY1 or HOG0 or HOG1. All these are mass flow SEFI for trucks with E4OD transmissions. I think there's a HOG0 on Ebay at the moment.

There's still reprogramming to do, but these will actually work.

 

Is it possible to "reprogram" my stock computer with an aftermarket program tool to run mass air? Something like the Moates Quaterhorse?

 

Funny. Mine runs like a champ.

 

Effectively, no.

Quarterhorse can accept a different program that the original, but where are you going to get that program from?

The real killer is that your original ECU has the input and output components for a Speed Density system, and not for Mass Air.

 

What would I need to have done to the HUG0 computer? Sorry so many questions but I'm completely ignorant when it comes to ECU's.

 

You don't want a HUG0, that controls 4R70W transmission. It's VEX1 or WAY1, or HOG0 for an E4OD. For those, you'd need to do all the wiring from the MAF and injectors that the HOG0 expects, verify that your E4OD solenoid pack is compatible with the HOG0 (a diode was moved between the solenoid pack and the ECU sometime around 1995).

Then you'd need to have a tuner calibrate various parameters of the HOG0, such as engine capacity, manifold volume, size of MAF, size of injectors, set the ECU torque table correctly so the transmission pressure is correct, and probably a few other things.

Those settings could be burnt into some Moates device plugged into the J3 port.

 

Holly crap you're speakin' German. If I pick up a HOG0, who can I send it to and have it programed? Would this be the "easiest" approach?

 

I've put a sd 460 in my 94 flareside 2 whl runs if put fuel down throttle body only no power to injector s or fuel pumps even if hot wire pumps still no injector pulse came outta my 88 f250 all rebuilt and .40 over now was a beast motor thanks please help

 

What EEC are you using, and what engine harness? The 88 and 94 engine harness to front end harness connections are completely different. 88 is 4 8 pin plugs, 94 is a single 42 pin plug.

 

I used 302;harness doesn't matter what ecm use does same thing even used injector harness everything from 302

 

Well, since you already seem to know everything, I will just step out of this discussion.
