Healtech eSync tool- synchronize balance throttle bodies

In theory these shouldn’t need that as they are sensors calibrated from the factory. Given they are solid state- nothing should change.

Interesting. I worked with a guy who claimed that in his youth he tuned his alfa romeo 33 (4 carburators) with a make-shift rig made of plastic tubes and plastic bottles. Water instead of mercury, of course

Regarding this tool: I don't get it: don't all 4 vaccum tubes go to a single MAP sensor? Won't pressures be equalized no matter what? I think I don't get what's really going on on the TBs and those vacuum tubes.

JT, there would actually be 4 transducers. One for each hose. The pressures would be converted to digital data sent to the attached computer for display. That's a simplified explanation.

My question is:
on the bike, there is only one MAP sensor, and the 4 vacuum tubes join together at some point, so all 4 pressures are equalized. Aren't they? So I guess, the ECU is using MAP as an average of the 4 TBs?

So I guess during testing and sync. with this tool, MAP sensor can't be used, or at least not in the same way as originally. Perhaps only connected to one of the TBs.
