OK I have a problem child 2002 Excursion that ran great when I parked it in my shop 6 months ago but now starts rough and while driving will billow black-grey smoke when you go WOT. It will shake pretty good too.
I took some data with my AE and the Baro / MAP / xxx are all within .5 of each other. I also datalogged ICP, IPR_DC and RPMS starting from idle, then to 1.5k and then WOT (3.4K). When you go WOT in park the truck shakes and blows the same black-grey smoke and shake. It will idle pretty steady afterwards.
The truck fails the CCT on cylinder 8 but It always has since I've had the grey CPS in. I slapped a new grey CPS in and there was no change. I also changed the fuel filter with the same results. Any ideas?
Now... it's hard to sort things out in Park - the truck has no load. You would want to see the numbers with a load, like WOT in gear on the highway. I have done 0-80 MPH runs in the past, this allowed me to get all the way through to OD with the foot feeling the floor. I do not recommend 80 MPH, as this will exceed any speed limit I know of... so enter at your own risk.
The PIDs you want (change out Transmission Fluid Temperature with Torque Converter Slip):
What you would see... if the stupid Album feature worked correctly... is:
Fuel Injector Pulse Width (Max 6)
Injector Control Pressure PSI (Max 3500)
Injector Control Pressure Duty Cycle (%)
RPM (Max 3500)
Manifold Absolute Pressure PSI (Max 45)
Exhaust Back Pressure (Max 55)
Torque Converter Slip (Max 500) - Don't panic when this goes of-scale, it should lock in at about 35 MPH or more when the transmission is warm enough.
Vehicle Speed (Max 100)
Engine oil Temperature (Max 250)
Thanks for the reply. I will test this tonight when I get home from work. The truck really falls on its face when jumping out on the highway so it should really be an entertaining graph!
Is there a chance your thread could be condense down to relative information. Not that other posts weren't interesting but I would like to have a go-to reference book. I made copies of what I thought would be helpful, but my brain is like what Timothy Leary must have felt when he introduced Acid to the Boomers in the early 50's.
That is a long-term plan. I have much more information that hasn't been conveyed yet, but I am absolutely buried in work right now. This might be a fall or winter project.
In the mean time, I have another AE thread with graphs and troubleshooting somewhere. I'd link it, but I have to get to work right now.
A quick AE question. Does a truck brain somehow keep track of the miles driven, and if so can it be found with the AE? My reason for asking is I found an 06 Ford van with 27k on it. The price is fairly good and I could use it, but I don't want to find out it was really 127k. I don't know if they can still turn them back or not. It is at a car lot. It is a club wagon with all the bells and whistles. They want $12,000. It looks like it is new.
If it has a digital odometer, i have heard of people swapping out the cluster. Mileage isn't tracked by the PCM, so if the cluster has been swapped and you can read it with AE, it will give you the same number as what the cluster reads.

Thanks for that info. I wasn't sure being new to AE.
