Hello all.
2016 Trend. Torque Pro and ABD-Aus. Have entered most of the TC and Trans PIDS from the PID Calculator here (appreciate the site.. it's awesome).
Have only had Torque Pro for a little while and this is my first experience with this kind of data.
In regards to the readouts I have in the attached files (Revs (engine torque), output shaft and slip across TC), can you please let me know if I'm understanding the following correctly.
- Slip Across TC is the RPM difference between engine RPM and Turbine RPM?
- There is a normal/expected amount of slip?
- Even when lockup occurs, the Slip Across TC may still have a reading due to the error margins of the sensor readings?
- Why, when I release the throttle does Slip Across TC jump up to around 16000 (even thought I have the max set as 5500 as per PID setup)
- During what I think of as 'lockup' Slip Across TC never goes below 20rpm. Is this a standard error margine for the sensor readings?
Thanks in advance for your help and patience with the non-mechanical minded!
Ryan.

Can't help you with most of it but I am wondering why the minimum temp for the trans is 41.8
I can understand the highest as not at operating temp.
I use the OBDLink app and trans and engine are close to ambient temp when cold.

Ross - I had been driving, stopped at shops, then on the move again, that's when I took screen shot. TFT was still warm from last drive.
At least, that's the best explaination I have.

Oh.. and for those wondering... I didn't touch the phone while driving... "Google, take screenshot" did all the work. No illeagle phone use while driving here.

The readings are correct.
There is always a little amount of slip allowed even with full lockup to limit the amount of vibration in the car. Between 5-50 rpm is normal.
The spike to 16000 is just a consequence of the reverse direction of slip as you lift off the throttle (it's a maths thing).

thank you! it's good to know the baselines while I'm learning all about what's under the hood.. or in this case, being the TC, under my seat..... I think.. I really need to look under there one day.CatHerder wrote: ↑Thu Sep 01, 2022 8:56 pm The readings are correct.

I used to be a farmer and herded cattle frequently but never herded cats.
I can only assume you have cats in huge numbers in Canberra.
Please enlighten me, and any others who may be curious how your name came about.

LOL, no Canberra connection.
I have led a few 4WD trips (tagalongs) over the years. Other drivers (customers) don't always go where you want them, or take direction in the way expected.
