Your thread title translates as "Those afraid of chrome unite!", chromophiles is what you were after i think
Rather then retard based on boost, i'd think you ought to have a full ignition map, based on MAP and RPM, and a knock sensor to tune it with.
they do give you the full table based on RPM and manifold pressure. that little box that you can enter the ignition retard per psi is only there to save the person the time of having to type in each cell of the spreadsheet one by one. as soon as you click to make those changes and view the ignition tables, you can see that they are all changed.
on the other problem, heath, i will open crome right now and see what i get. like i said before i have yet to run crome on my car, but i have had uberdata running though.
okay, i opened crome and did what you did.
file -> new -> P72 rom.
plugins ->advanced boost tools+, i chose stock honda map sensor and 8 boost columns. okay.
now if you look at your fuel and ignition tables you will see that all the boost columns have the same value in there across the board. you will need to run the tools->boost tables adjustments to recalculate the values. do this that choose 0.75 degrees/psi and 120% efficeiency. now if you go and look at all the value in the tables, the have changed accordingly. perfect. good.
if you run the boost tables adjust again, the "do not make changes" has been checked, but this doesnt matter since the tables have already been adjusted. don't worry about it. i agree that it kinda seems like nothing has changed, but it has.
with your other problem of injector scaling and engine size scaling. what you need to know is that the values as seen in the tables are not like uberdata. in uberdata the scaling multipliers actually change the values in the tables for you to see. in crome, however, the original values remain the tables for you to see, and the fuel multiplier is applied later. okay, now that we have this understood, you want to set the fuel multiplier.
by scaling to 450cc from 240cc, this gives a mulitplier 240/450=0.533 okay. if you click okay, you will notice that the colour of the cells change to a lighter colour. this lets you know that the multiplier has been applied, even though the values inthe cells don't change. if you then scale the engine size up to 1972cc from 1595cc this adds a multiplier of 1.236 for an overall multiplier of 0.659. this makes sense. when you click okay, the colours in the cells get darker, to let you know that the fuel multiplier increased.
when you open the fuel multiplier menu again, you will see that the multiplier of 0.659 is still there. what crome does is only store this multiplier. and then when you open the fuel multiplier menu it then fills in the value of ONLY the "new" injector size accordingly, based on 240cc and 1595 engine size. this is how you get 364cc injectors because 240/364 = 0.659. since the overall multiplier is still 0.659, then things are good. it would be better if crome saved the value of the injector size and the engine size, but it doesn't so as long as you know whats going on, it doesn't really matter. as long as your overall multiplier always stays at 0.659, then you are okay.
hope this helps
