Been playing around with MS3X on a standard 1996 1UZ with standard 251cc injectors.

After lots of searching, does anyone have an accurate injector dead time or pulse width figure. I'm currently using 0.9ms and the standard MS3 dead time voltage% curve table.
 
Thanks for the response.

Is the increase/decrease in pulse width linear or does it ramp up/down? The MS3 allows for a "Dead Time Voltage% Curve", and uses 13.2v as the 100% reference line. I've been using [email protected] but I've seen 0.94ms and 1.0ms at the same volts also used.
 
It ramps. 0.1ms shouldn't make enough difference to the overall result. Just don't go changing them once the tune is complete. MS3 fuel calculations tend not to be extremely accurate so the tune generally has a little safety margin and the 1uz is pretty forgiving to work with.
