Just got word that my tach is bad. I have an AEM computer in the SVO and I thought there was a problem with the signal to the tach, but the shop said the tach is bad (this is the same shop that installed the AEM and performed the tuning, etc.).
I don't know what they checked, or didn't check. But they are pretty good (IMO).
What (if anything) should I ask them to double check?
Other than mounting an aftermarket, what other options are available? I thought about just a shift light. Is there a replacement that would work (and how much of a PITA would it be to install it)?
