MS3 Dead Time Setting for RDX 410cc
I am using Acura RDX 410cc injectors in my 2005 Miata with 1.8L VVT engine and running on Basic MS3 .The TunerStudio Injector Dead-time/PWM setting page is quite confusing, need some help in verify my settings.
It ask for dead time @13.2v a data point which I dont have so I have to calculate from the other data point I found online. Then on the graph it uses percentage of @13.2v I assume because on the graph 13.2 was not referenced? Then whats the difference between the " A(ms) " in top part of " MS3X Injectors " and the "BANK 1 Dead time @ 13.2V(ms) " bottom part of " Mainboard Injectors "

MS uses 13.2V as the "zero point", use maths and calculate what percentage the dead times are, at 10, 12, 14 and 16V and input those values into the table in the top left graph of your screenshot there. MS will interpolate the rest.
The "A ms" through "H" is just for different injector banks so you can tailor curves to each bank. Unless you are running a crazy staged injection setup with different injector types in each stage, ignore it all and just use the "main board" value with "curve 1" as indicated in your screen shot, which you will see, will fill in the "A" value if memory serves me correct.

You don't key it in. The point is that it is better to use the 70 psi data than the 43.5 psi data, and when the dead time is most important (low MAP) is where the differential pressure is approximately 70psi.
