The throttle stop is not how you relearn the TPS, these are different than the old days when you'd rotate the TPS in pursuit of a desired voltage. Here's how it works on the LS1, I'd give this a whirl.

How to reset/relearn TPS????? - LS1TECH - Camaro and Firebird Forum Discussion

PCM Diagnostics & Tuning - How to reset/relearn TPS????? - I know this is simple, but I can't remember the sequence. I had to make a manual throttle/idle adjustment on my throttle body (1998 style LS1 cable throttle). I actually had it open by 1% at all times so it wasn't ever going to total...

Also, check your before and after TP at idle and let us know what that was.

Ok, followed procedure:

And throttle position was 0° before and after ^^^procedure.

Definitely being monitored as well. So, that about confirms TPS is learned and functioning.

I guess you were referring to @454cid there.

My truck has always idled funky. And it’s been down a few months but I remember mine idling between 6-700 when it ran “right”. Let me know if I can be more vague

At least you posted! I’m willing to bet most are similar.

I don't understand why there's a listing for "Engine Speed" and also one for "Engine RPM".

Is one of them "commanded" speed, and the other is "actual"? If so, why not tell us that one is "commanded" and one is "actual".

I literally messaged Dash Command today and I asked specifically which is the “Commanded” and they said it was the SAE.RPM which is the “Engine RPM PID in above picture.

 

[Caman96]

@Schurkey is the “Commanded” a fixed number or is it in flux from different parameters?

 

[Schurkey]

Commanded RPM would vary with engine temperature, A/C operation, perhaps in-gear/in neutral/park, and potentially other factors.
