Re: VATS

Hi, Keith.  There's a couple of ways to do what you want.  You can
build a circuit to generate the signal the VATS module sends to the
ECM, or you can change the calibration so it doesn't expect VATS.
2 places to look for info come to mind:
The DIY_EFI Archives: http://efi332.eng.ohio-state.edu/diy_efi/
The GMECM archives:   http://efi332.eng.ohio-state.edu/gmecm/

Ever notice how it's always "back east" or "out west"?  Somehow, "out
east" just doesn't seem right.
