Stock injector dead times

Anyone have values for the stock primaries? When the fan kicks on and voltage drops my idle suffers big-time. Currently set to 1.0ms and it swings like .4ms each direction accordingly

possibly...I havent been able to track those down either. I did see one thread about values but it was questionable if they were correct or not.

What ECU are you using? I assume you're asking because it supports a 3D dead time table (dead times vs differential fuel pressure and voltage). This is one of those situations where I find it's much easier to bite the bullet and buy a new set of ID injectors that come with dead time data you can trust, rather than wasting your time scouring the interwebs for dead time data on the FI's that you got - even if you find the data out there it's rarely correct & useful for what you got.

The MS3 pro can adjust deadtime based on voltage scale yeah.

I dont want to waste a bunch of money getting radium rails and injectors, just to get rid of them when I go ITB...so if I can get close enough that would be good for now.
