I recently purchased AE, so I'm not sure about the "upgraded connector". I can tell you it worked very well for finding bad injectors. Mine will do the power balance test, but I found that being able to turn off injector one at a time while it's running to be the most useful. Started out with a code for the #2 cylinder, turning of #2 while running made no difference. Turning off #1 didn't either. Changed #2 and tested again and #1 had a power balance code. Changed #1 injector, problem solved. The power balance test showed an RPM increase on the #1 cylinder. I suspect it was dripping excess fuel into the cylinder, and I did have a lot of white smoke until that injector was changed.
I'm not sure if I have answered your question or not, as I'm not sure if I have the old or new connector (I purchased it in Jan of this year), but either way, it allowed me to diagnose 2 injector problems and pin point which injectors were bad. So in my opinion, it works very well, and it was worth every penny I paid for it.
I have also read that when one injector fails, the rest wont be to far behind it. The power balance test also showed a slight RPM increase in the #8 cylinder. But turning that injector off with the engine running made a big difference in the way it ran. It will be interesting to see if #8 is the next injector to fail. The truck is an 04 with a 6.0 in it. I did this test on a friends 06 and the line was flat. If #8 is the next one to fail, that would tell me the power balance test is a good indication of which injectors are on their way out. Only time will tell.
Bill, you should have a new connector. I think it is labeled with Proline. Mine has AutoEnginuity only. I called them and was told I would need a newer conector.
Sounds like it will be worth the money. It is around $100 for me to upgrade. Had mine for over a year now. Helps that 3 of us may be splitting th cost.
I have at least one injector suffering from stiction, maybe more, and an intermittent miss when warmed up. I was planning/ hoping to just replacethem all, but after a rebuilt trans and fuel pump and blue spring and.........
Other than selecting "power balance" on the drop down menu and clicking on "initiate" do you have to do anything else to get the info to display in graph form? I've got the proline connector but I haven't been able to get the data to display in a graph.
