What gives the tachometer signal? Ecm or Bcm? I know it comes from the crank sensor..

Hello there, I am Cam.

I am Licensed technician at a GM dealership with more than 16 years experience. 
Like you, I am a user of this website and as such, any billing questions should be sent to customer service.

I ask that you please provide details and communicate with me so we can make your experience here worth 5 stars! I am around most days but not every minute of every day. If you reply while I am offline, I will respond when I am next online.

What codes do you currently have set?
Is the Tach the only issue or are there performance issues?

The engine speed signal is measured by the engine module then sent on the data network to the cluster where it can display the speed.
