It’s less about the distance and more about the volume of the hose.doc_rot said:In the instructions on the motion pro and on the Morgan carb tune, iirc both state the little nozzle you poke in the end of tube needs to be within a certain distance to the vacuum source to function correctly. I dont know how important this is but both carb syncs I have owned stated this.
This made a lot of sense to me. Thanks Farmer.farmer92 said:It’s less about the distance and more about the volume of the hose.
If the volume is to large, the vacuum signal gets lost, it’s harder to sync.
It’s not a constant vacuum, it’s vacuum and pressure pulses. So if the volume/length in the hose is too large compared to the intake volume then you don’t have the same pressure drop you would with a smaller hose. The signal is harder to read.
Tl;dr the hose length is a valid point to consider, all lengths need to be somewhat similar.
