I and as many other people use the kodak or fuji times anf steps for c-41 dev with the digibase kits. And yes, we must wash after fixing. I asked about the consequences and how/what to do to the negs, in a different thread: http://www.apug.org/forums/forum40/1...er-fixing.html
I think when first developed c-41 I wash after fixing, but when I was looking to the steps/time table that I made to be near the processor, I thought, strange, in E6 one must wash after the fizer, but the c41 only have a wash cycle, but never thought of going to see all the steps here.
