I am trying to sort out an injector duty based water injection system.

We can get a signal from the primary injectors with no problem. however the next problem is the transition. When the primary reaches the set inj duty in the settings it switches on the secondaries. It then reduces the inj duty to compensate for the secondaries being online. This causes the inj duty to drop dramatically eg from 48 % to 30 % on my car.

What can i do to combat this ?

could i do the transition earlier ?
