Re: MSD Atomic EFI on '79 K30 in Cali
Okay my 86 came with a Rochester feedback carburetor with a dual capacity pump my computer controls the spark timing EST so I do not have vacuum advance I had to also buy the MSD throttle position sensor to make this work cuz I do have a check engine light also the air injection has a diverter valve that diverts air between the exhaust and the intake the air injection goes into the exhaust manifold before the O2 sensor I mounted the MSD O2 sensor past where the y- pipe connects
