@DavecUK and all:
For the next while, I will be focusing on learning to use the Lelit Elizabeth, to improve shot taste and consistency.
After that, I might think about a “pressure profiling mod” or alternatively a “flow profiling mod” … If… the preceding will work with (not interfere with) the programming of the machine. Or otherwise adversely affect it.
For example, I effectively used a rheostat connected to the electrical input of my Breville DuoPro pump to control pre-infusion ramp up and shot ramp down.
What about flow control valves? Has this mod been done? What in the way of aftermarket parts/kits are out there? Would this work on a Lelit Elizabeth? Is it A good idea?
Other mod ideas?
Don’t shoot the writer on this. Just musing.
