Hi Pierre,

In my case I have shorten the corrugated hose from the Y to the T piece, not sure by how much but it must have been a good 5 to 7 rings. An important aspect of the Y piece is to remove the O'ring on the cell if it has one. If you buy your cells from APD they come without O'ring but from other suppliers they might. If you keep the O'ring, it will make a difference in the pressure between the front and back of the cell. This will make the tracking of PPO2 between the VR3 and INSP controller to go out of sync with time. Had a big debate a few years ago about this when the Y came out. I personnaly do not recalibrate the VR3 for every dive, once every 3-4 weeks works fine for me.

Cheers,
