Question Regarding the data I saw about EMPS using techstream, I don't know if this is correct

As you can see in the picture, the angle of my torque sensor is not 0, and it will change when I turn the direction, but when the steering wheel is in the middle position, it displays the data as shown in the picture. I don't know if this is correct, should they be 0 degrees?
There are also other data in this picture. I don’t know if there is any wrong data. I hope someone who can understand can solve my doubts.

Hi, do you mean that when you use Techstream to enter EMPS to view the data page, do you not have these two data? Or are the two data you see are 0?

My bad, let me clarify.

You reference some pictures in your post. I understood that to mean there were supposed to be some pictures attached in your post. I was just letting you know that at least for me, no pictures showed up in your post.

EDIT:
Oh weird. I switched connection and now the page loads. Disregard my post.

It's okay, so can you understand this picture I posted? Including whether the two data I circled in red are correct.

Best I could do would be connect mine up to see what values I have to compare. But, it wouldn't be today.

Posting what mine was doing. They were both around the 270ish degrees mark for torque sensor 1 and 2. But honestly it changes around a lot. In the picture attached it ended up being 0 and 358. I couldn't tell if slow constant torque to the wheel was the same as quick turning motions because of the slow refresh rate.

​If you click the graph at the bottom, it'll graph it out a value (you double click what you want). But, mine would only sample ever 5 to 10 seconds, which was annoying. The graph is just turning the wheel left to right then right to left. If I left the wheel anywhere without moving or touching it, it would remain at that value. Basically that was my only take away: if you left the wheel in any position, centered (not holding it applying some torque), it would stay relatively constant at whatever value it was at.

Sorry for the phone pictures. I had screenshots but laptop kept crashing towards the end (it's old).

Looking again at both your picture and mine, I wonder if the value under your red square (trq1,2 zero point value) is the actually the "zero" or center point. For mine 274.6 and 273.1 are the zero point, which matches with the 270ish observation. And your 64 is close to the 61 you have.

Granted I don't know what sets that zero point value.

I have Techstream also. Currently the laptop that I have it loaded on is in the shop. So I can't look at this.

You may want to ask this on the GSF, RCF, ISF or 2nd Gen IS forum. They are a lot more knowledgeable about Techstream and more use it there. There are also some Toy/Lex shop Tech on those forums also. They can likely help a little more with this.

Thank you very much, I think you solved my doubts, after reading your test, I think my data should be right. Thanks again!
