I have alot of info on all the fun stuff about the IAC, that no editor provides menus for. I was wondering if any of you here have more info on the stuff inside the 7747.

Yep! Go to the DIY-EFI site, and find ECMGuy's web pages. There you'll find the '7747 HAC, which shows a LOT of other stuff. Might be a bit difficult to read, but it's not too bad.
Definately find that hack. I have it (PDF) and it helped me so much... It basically gives you the entire operating proceedures/parameters of the ECU, and of course all addresses!!! It takes some time to filter through as it is rather big and the SEARCH function in Adobe gets a workout but worthwhile for sure. Good rainy day stuff. I don't have the address for it though but am sure it was DIY. I'll go into the file and see if there is something on it...

Bob R. has posted some really good stuff on the 747 at incoming (DIY-EFI List), lean cruise patch, how the IAC PID stuff works, etc.. Stuff also applies to other ecms all of it a must read

I've been reading the "hiway-7747" hack that Bob put out. I'm assuming this is lean cruise mode.. I like! I think I'm going to try it in my CrossFire! Any thoughts, Grumpy?

I'd try any of Bob's patchs, he's excellent with the 747.
I'm looking forward to getting the 747 running the crossfire and getting the QJet off, and replace it with a single 2 brl TB instead of the dual singles.
I have the 7747 ASDZ hack on my computer here at work. If someone would be so kind to tell me how to get the file posted here, I will do it as soon as I can. I need explicit directions, please...
Guys, I believe it's in /incoming under the DIY-EFI FTP site. That's where I found it - it's a zip file called "hiway747.zip" - the instructions are inside.
Remember though, TunerCat does NOT have the extra tables/constants in it's defintion for the '7747, so you'll either need to get WinBin or Promedit to change things (an .ECU file is included in the ZIP file) *OR* you could get TunerCat's TDF editor and put those tables/constants into TunerCat so you have one simple solution.
