Sure!

The binary code in the Ford EEC-V PCM is made up of 4 "banks" of memory. They are numbered 0,1,8, and 9.

The emulator uses a 32K-size file that is made up of bank 8 of the binary code in the PCM (where most of the maps are). When using the emulator, the truck operates on banks 0,1, and 9 while the emulator supplies bank 8.

The definition file for the emulator is also different than the standard definition so that it has the capability to change bank 8 inputs to the emulator.

So, the 224K files that you have for your tunes need to be broken down into a 32K file that the emulator definition can use.

The "romulator" is unable to operate all 4 bank changes.

Awesome.

Is there things that you cannot change when using the emulator because of it only using the 1 bank of inputs?

How does the emulator work, can you make changes "on the fly", or is it more like make a change, load file into emulator, and continue?

What does it take to change file to the 32K size?

Yeah, there are a whole lot of things that you can't change....namely the "parameters" and a whole lot of "functions". Most everything in the "maps" section can be changed.

How does the emulator work, can you make changes "on the fly", or is it more like make a change, load file into emulator, and continue? Yes, you can make changes on the fly. There are times that you will get a "bump" or momentary loss of PCM (stumble or stall) depending on what you change and when you change it.

What does it take to change file to the 32K size?Hex editing software like HEX WORKSHOP. Then you simply select the 32768 bytes that you need (address E000 to 16000) and paste them into a new sheet, save it, and load it into the emulator definition.
Hope this helps.

Is the software included with the emulator, or a separate buy?

Actually you don't need any software. You attach the emulator adapter to the PCM (where the chip goes), hook up the emulator (via serial/usb adapter), go up to the "Romulator" tab in Minotaur, select a COM port, and hit connect. Then you download the 32K file you made, and start the truck. You will need the emulator definition though and Bill didn't charge me for mine since it's basically the same as your existing definition but it's made to work with the emulator.

You can select a box that says "real time update", which changes stuff on the fly or you can make some changes and hit "download" again and download the changes to the emulator. The engine will die when you do this and will require a restart.

Ok, how about the HEX WORKSHOP program, included or seperate?

Download off the internet. Free.

Yep, just paste the modified 32K binary into the 224K file and VOILA!!

Ohh... and after you are satisfied with your program, do you have to convert it back to 224K to load it on the chip? How does this work?

Yeah. That's it.

What you need to do is delete the first 57344 bytes. Use the "edit" and "select block". Then with the selector in "dec", type in 57344 and hit "ok". Delete that block. You should start with a hex value of "27FE".

Select another block of 32768 bytes and copy that to a new hex editing window.

There's your emulation binary!


When you go back in after changing, use the original 224K binary and insert the modified 32768 bytes into the 224K program.
