I dunno about 18V, but you're probably not seeing a difference because you're not using even close to the load that a "normal" vehicle sees.
The ECU that you don't have, in some cases a TCU, BCM (Chryslers), high-tension ignition system, etc. all have to work on that measly 12VDC, so there is an advantage to overvolting to 14VDC, in that there is less voltage sag should everything decide to harmonize the battery draw at the same time.
If you've ever driven a gasser with a bad alternator, you know that it starts running like a wet dog right about the same time your headlights get dim. If you turn off the headlights, you get power back, once you turn them back on, you lose all power again. I drove my 1994 Hyundai Excel GL with no alternator for about 2 months back and forth to work... took 2 batteries each way.
