The cylinder trim function, all the advanced maps for the PClllrefer to cylinder 1 as the rear. Is this a default or can you choose front or rear? Thanks.

 

You are correct in saying the rear cylinder is #1 and the front is #2, this isthe default. Now if you demote the map from advance to basic you can select what cylinder you want to use as the basic, Front or Rear or an Average of the two but the cylinder trim will always be #1 for the rear and #2 for the front.
