it applys the patch to the bin file, but you have to put that file in the eprom or chip with a proggramer

what patch, I'm lost, this is frustrating, so, tuner pro does exactly what, lets you make changes to the bin file? what does that do?

it will change a lot of setting or apply the patchs in the paremter tree to your bin file, but the bin file has to be programmed to a chip then installed in your ecm before any things will change in your data log or the running engine.
Sorry I didn't reply soon, been real busy.
I actually only have 1 jeep I have installed injection on and tuned. A 79 cherokee with a AMC 401 V8. I do have plans to change the 4.0 in my 93 YJ over to a GM computer, but have not had time to do it yet.
The 7747 does not natively display spark advance. As others have said on here, you have to apply a patch to the bin file to make it to where it will display spark advance in the datastream. You then burn the new/patched bin to a chip and put it in your ecm. You then use the correct ADX to view it. That is the extent of my knowledge on the 7747.
I only ran a 7747 ecm on mine for a very short time before I upgraded to the 7427, so I remember very little about tuning the 7747. I know one thing that drove me nuts was the snail slow datastream on the 7747. I much prefer the 7427 myself. But there is a steeper learning curve with it.
There are others on here who are much more knowledgeable with the 7747 than me. Hopefully one of them will chime in.
79 Jeep Cherokee, AMC 401, T-18 manual trans, hydroboost, 16197427 MPFI system---the toy
93 Jeep YJ Wrangler, 4.0L, 5 speed, 8.8 rear, homebrew hub conversion and big brakes, hydroboost, 2.5in OME lift, 31x10.50's---the daily driver
99 Jeep WJ Grand Cherokee limited, 4.0L, auto, 2wd, leather and power everything, 99% stock---the long distance highway ride.
thank you jeepsandguns, you aren't kidding about the slow data stream, its a bit ridiculous. I'm currently in a battle with my yj not wanting to idle smooth or start right up. I have found that it runs a lot better with the base timing at 0 degrees, instead of 8. But set at 0 degrees, it doesn't fire right up, its about a 5-10 second crank. And the idle isn't perfect, still rougher than it should be, but far better than at 8 degrees
