Aftermarket throttle body plug& play right ? WRONG
 

Installed new throttle body on a once smooth idling M54. (225k)
Once installed...
The idel is crap[emoji107] crazy! Idel bounces up and down, up and down.... never settles down or smooths out!
Smooth as butter before I installed the aftermarket TB.
Doesn't recognize the gas pedal!
I'll de-install tomorrow!

Do these need to be callabrated?

What gives?

You need to reset the throttle adaptations when you install a new throttle body.

Correct!

Did an hours of reading and your right[emoji106]

Is that the hold the gas pedal down for 10 count!
Or
Do I need software ?

Using your foxwell nt-510 is easiest

You can also do it with INPA or MS43X (both free) an old laptop, and a USB cable. This is the one I use and it works fine. https://www.amazon.com/dp/B07GRG44FP...d_asin_title_1

Got to find the foxwell...in storage somewhere.
Installed a boneyard unit off the shelf... now I'm back to the magic carpet ride[emoji106]...now where is that foxwell!
