Anyone have ideas that have done it before? I've looked around, and like the idea of the steam infusion system you can build with a pressure cooker. Would enable one to do step mashes at the proper ratio without having do much work during the mash. Any other ideas out there? Just trying to get some ideas together to see what I can "cook" up this year.. I probably have another year on my system as is before I finally break down, and get my welded up single tier and get a direct fire mash tun with a pump to recirculate.
Are you talking about injecting steam to increase mash temps in steps? If so, I have no experience with that technique. I do regularly create step-temps in my mash tun (cooler) by simply adding hot water. For the most part, I can accomplish three steps without great difficulty. I find (and other knowledgeable sources agree) the water/grist ratio can have a moderate range, i.e. start at 1.1 qts/lb and end with ~1.6 qts/lb. A water-infusion calculator is necessary, I find brewersfriend actually better than beersmith.
It's pretty simple to add boiling water to the mash to step up... up to a point. The low tech answer is to do decoctions. I like them but am too lazy to do it as often as I should.
As port largo has done, I have done step mashing once. Pretty simple. I use brew 365 calculator and enter each s temp I want to reach and enter current grain temp and it tells u what your strike water shoud be to reach your next desired temp.check it out.

Pretty much do a two-step infusion mash every batch. Start out a little thick in the mid-to-upper 140s, add a small volume of hot water to raise the mash temperature into the low-to-mid 150s.
I have step mashed by decoction and by adding hot water to an (initially) thick mash. Never heard of presure cooker steam infusion. Sounds interesting though.
