Advance 123 distributor and GoWesty throttle body, Questions about the install... Options

[TRP]

Hey Gang!

I am about to stuff the 2056 back into my car and I wanted to double check a few things before I dive head long into this thing.

My A123 has a vacuum port on the side of the distributor body. The GoWesty throttle body also has the vacuum port. I assume I connect the TB to the A123 ports and I'm good to go. I ask because there are lots of comments about 'if the port is before / after the throttle blade. The port appears to be in the same approximate location as the stock 1.8 TB, so I think this is correct.

Second question, with the 2056 and the Raby "FI compatible" cam, the rest is stock L-Jet FI (I moved the TPS over to the GWTB) -- which of the pre-programmed advance curves should I be selecting in the A123?

Thank you!
Ted

Depends if that 123 is looking for manifold or ported vacuum. I wants to say that 1.8 only had one vacuum line to the dizzy stock, and I am a djet guy so I don't know if that was advance or retard. By the time of the ljet, djets were only running retard.

If the new dizzy is looking for ported (advance) them you need to make sure that port only has vacuum as the throttle just opens. If you are looking for retard then it needs to have vacuum when the throttle is closed. That said, you don't really need either with a 123.
