I was working in Asheville, NC this week before arriving at RRE. I pulled my camper to Asheville.

There is a long grade on I-40 from Asheville to Newport, TN (Home of RRE). I thought that it would be a good opportunity to do some data logging with my AE. I really didn't know what to capture, so I used Wood-N-Things WOT HPOP testing parameters, but left one off to put in " Torque Converter Slip Actual (RPM)".

I have the data, but really don't know what it means.

I was suprised at the Exhaust back pressure readings. I did use my decel tune when I came off of the interstate. After looking at the data, I thought it would be a good point to see when if the data supported me coming off of the interstate. @ 12:43:59 PM, it shows the Exhaust Back Pressure going to 36.14 PSI. That is about the time that I came off of the ramp. However, there are other times that the pressure gets above 30 PSI and I know that I was still coming up the Interstate. That seems confusing.

I am hoping that the column "Torque Converter Slip Actual (RPM)
[0 - 4000]" is showing something good. It seems to me that my new OEM HD tranny and Torque Convertor are working correctly.

If someone can find something in this data that causes concerns or points to something that needs to be checked or addressed, please let me know.

I am at the KOA with a bunch of experts, so if I am in a great place to correct something.

Thanks.

 

With 43 pages of data it is a little tough to go through it all, but it looks ok. Next time, if you are doing TC Slip, also measure mph. That will tell the tale if it is locking where it should.

 

thanks. It is a little easier to sort in Excel, but only PDF's allowed for uploads.

TQ slip is single digits except for the start and stop when I was idling.

@ 12:34:15.218 my duty cycle went to 65%, but right after that, the HPOP went to 3300 PSI. I think that HPOP lags the duty cycle, so that looked okay to me.

Thank you for looking at my numbers.
