I am planning on swapping a complete 5.0 Explorer engine and trans into my ’87 Mustang, computer and all. I figure I get a flash tunable CPU, MAF conversion and EDIS. The potential problem I’m seeing is that after reading this board it seems you want a strategy that is well known and the Explorer CPU is apparently not popular. Can I load say a CDAN4 tune into the Explorer computer? If not can I use a CDAN4 computer with the Explorer wiring? Anyone seeing any other problems with this plan?

You need to know what year Explorer EEC you have. 96-97 were 2-bank. 98-01 were 4-bank.

It's a 97, code on the CPU is XDT2. I noticed someone uploaded a bin file in another thread. Is that all I need to tune?

[cgrey8]

You need a def file to display the bin file. The bin is the raw BYTES as they were sucked out of someone other XDT2 EEC. However there's no human readable info in there.

A def file is what puts meaning to the various values that are in the bin. Incidentally, the bin is also the executable code that the EEC runs, not just the data. So when def-file developers are developing def files, they have to be careful about what they are pointing at. It's a lot of reverse-engineering and assumption-making to develop a def file. So paying money for somoene's def file is not unreasonable given the very specialized expertise and time it takes to make them.

I believe sailorbob has a def file capable of displaying XDT2.

OK, so it sounds like using the Explorer ECU is doable then. Is private message the best way to get ahold of someone on here?

CGrey8 Is the person responsible for the tuning software and the QH itself. If anyone can answer your question, it's him.

You actually have a 2wd explorer transmission? Those are pretty rare! I'm more interested to see how you're gonna make a truck 4r70w fit in a fox body. They're a bit longer than the AOD/T5 that was originally in there.

If you really want distributorless ignition, I don't have an answer. However, I have a solution that will drive the transmission. A 94-95 Mustang 5.0 Auto computer will control that. You can use your original harness, just add the associated wiring to the eec connector and move around some wires. This computer also gives you the ability to run a 2 speed electric cooling fan.

you give me way too much credit. It's true I am the maintainer of the GUFx defs, which are open source. But I'm not the guy to thank for the technical knowledge that made a lot of those defs possible. That credit goes to sailorbob. What I take credit for is cleaning up a lot of the language in the "english" portion of the defs, correcting things when they are found, and adding comments as I learn nuggets of knowledge that I don't want to forget (and thus that might help others). The defs are far from perfect, but they've come a long way in the 8-or-so years I've had my fingers in them.

As for the QH, I can take even less credit for it. The QH is Craig Moates brainchild. And BE is Clint Garrity's.

And when it comes the the Explorer EECs, I'm not the one to ask questions to. I don't use them. I don't maintain them. And I know very little about how they do what they do. Sailorbob has a def file that works with the XDT2 EEC. He'd be a good source to ask for specifics about the Explorer EECs. Decipha is another.
