[Gmecm] Zeitronix Zt-2

[Mark Romans]

I don't know why you couldn't use the stock location!  I have one installed
I did weld a bung at the Y-pipe on my 87 vet so I am sampling both banks.
I am using the simulated narrow band out put to replace the factory sensor.
This thing is beutiful how it works!
