Re: Magnetic VSS output voltage

Re: posi 1987 4612825 Unit

Can you carefully count the splines for the axles and teeth on the ring gear? Also, the diameter of the ring gear is important. I may want this as a backup. Thanks

Re: Anyone in Massachusetts?

How are they trying to get it back up? I just clicked through the home button a dozen times and it's working...but if the forum is deleted, it's gone. Should we try and get donations for a new one?

Re: FAST ez-efi retrofit

So do your gauges work? Is the C.E.L. on all the time? And did you have a 700r4 at first? I don't know if you had overdrive functioning, NBD.

Re: FAST ez-efi retrofit

Your impression is right, the dizzy has to be vacuum advance or dual-sync types and some type of HEI with a tach signal has to be present

Re: FAST ez-efi retrofit

I believe from looking at your stuff, you used EZ-EFI 2.0? That one can control timing. But if I'm wrong, could you be specific as to which "boxes" I can choose from for an '87 L98 TPI?
