Once I get my new toughbook set up and running, I'll get the 7747 ecm hooked up and going this weekend. This truck is my daily driver and am not really into risking anything at the moment.
Please bear with me, I am still learning the software.

Mark,
Is there a summary anywhere that lists and explains the mods to the 7747?
Also, for whatever reason, I can not get TunerPro RT to recognize the cable. It once worked and no more. I've verified port settings and was using the same files as I did before when it did work.
Ideas?
Drivers? Here's a check list that has always worked for cable and TunerPro RT:

What mods? Hacks for spark and BPW are built into XDF, disassembles are in info thread.. same chip as you've been using...Is there a summary anywhere that lists and explains the mods to the 7747?

Got the Tunerpro to connect finally. Just decided to work.
What I am curious about, for one, is the Highway lean hack. I want to know what that does before just implementing it because others have done it.
Well first off no one should use it until their tune is in order!
What it does is meets a few qualifiers like Min Coolant temp, Min MPH before it starts a timer in seconds, then enters Open Loop to AFR specified in Hiway AFR table and also add Hiway Spark advance to compensate for leaner mixture. It is turned off by a MAP setting if load is to high or if MPH drop below setting and goes back to Closed Loop.
Hiway Lean Cruise should also use the ESC Done patch to eleimanate need for forced knock test to be done before entering.

It's also covered in the ASDU3 disassembly done by Jimindorris:

Thanks Mark, this is the kind of info I am looking for.
Drove to town, about 25 miles to get a cf-29 toughbook with an actual working touch screen. I did get a data run with the Tunerpro on the other laptop I have and will upload shortly.
When and if your ever ready for Lean Cruise let me know. I've built a patch into new $42-1227747-V6.xdf actually several patches.
What's a CF-29 Toughbook go for there and how much work do they need?
I've almost dropped my Laptop a couple times, been flying off seat several times, lost one to a cup of coffee through keyboard... would love a new fast one but at $2500 I think an old slow one and my desktop replacement type laptop would work fine with wireless networking.
