AutoEnginuity questions
Ok i have been here for a while now. And am thinking about the addition of AE to my tools sometime this winter.
I have a few questions that i am unsure about and havn't really found the answer to.
When you log say the Timing, HPOP PSI, peddle position and so on. Will it allow you to see them on a time line.. Like 3 seconds into a log will it show the points on the same timeline at 3 seconds for all selected sensors?
I just want to be able to compare hpop psi, to peddle position and a few other things but i want to be able to see the parameters at the same time to see what one is doing compared to the other at that instant and be able to graph it.
thanks for the help.
ALSO if anyone would have some screen shots of some of their testing i would love to see it as the AE site doesnt show all that much.
Pm me and i'll send you my email if you don't want to post them up.

it will show any sensor you choose on a strip chart or as just a number output. When you log the data you can play it back and it will show you all of the sensors at once (two per strip chart). It will also save it to a .csv file that can be easily opened in a spreadsheet program like Excel and plotted on the same graph.
Let me know what kind of screen shots you want to see and if I have a data file that matches it I will post it then or email it to you or I can get you a screen shot of anything you want sometime tomorrow.

I have two things to say here. First, the sampling rate of the AE is nowhere near the rate the PCM looks at the data, that is due to the interface I'm sure. So it reduces it quite a bit. I would even guess more than a second between data points in some instances. Having said that, it will sample all the selected sensors at that rate and give you a good pic of what is going on at that time. Not several times a second though.
Second, the AE will do all sorts of things, but it will not tell you exactly what is going south unless you know what you are looking for. Those values are just that. Values, and a readout of values is of little use unless you have a shop manual that gives you the normal values. Of course it will pull and clear codes, but it is more useful as a diagnostic tool when you know what you are looking for.
Hope this helped some. I could post all kinds of data logging screens but maybe you ought to go to 7point3.com and have alook at what Alan has put together for a baseline on an engine health check. Good stuff.
