I try for the easy first, if that does nothing, then a timing change is next, but a very small one. On the new software, for end user, you go to the timing tree on the left. Link the module, read the map. Leave it linked, motor is off of course, and make a live change, which means that you do not need to initialize again. But, after this change, save the map as something OTHER than the base map, by changing ONLY the last 6 digits, to the date is good.
Now to make the change, I am going to assume that cruising is ok, but under acceleration is what is bothering you with a ping. So, select Timing on the tree,
then go all the way to the bottom of this tree. We are going to make a slight change all the way across the board at those suspect rpms.
Notice there is a chart rear vs tps, and the next one is
timing vs engine speed. This is the one we want.
Open it up. (you are still liinked at this point BTW) look at the boxes. Select one around around 2645 or so. Now, hit space bar. This will show you the RPM you are actually at. So, to retard the timing, we are going to take the range as shown, and retard it a touch. go down, and smooth the line off. Since you were linked, the module takes it live. So all you need to do now is save the map youjust made, as above. Jur done.
Hope this helps

Brad, there is a Phillips 66 on Springfield Road in East Peoria, just down from the UAW hall that sells 93 without alcohol. You can give it a try, but I seriously doubt it will make a difference in the pinging. Might get better gas mileage, though. Try it and let us know.
