Speshi Racing Posted April 19 Report Share Posted April 19 Anyone can help me set a pulse width modulation PID control (nitrous solenoid) Storm Black ECU Quote Link to comment Share on other sites More sharing options...
dx4picco Posted April 19 Report Share Posted April 19 what does the PID has to do with PWMing the Aux output controling the solenoid? what is the value you want to control in closed loop? Quote Link to comment Share on other sites More sharing options...

I have the nitrous activated and working with on/ off switch at the moment. I want to create an progressive controller. At the launch I want a fix percentage of nitrous and increase the Hertz after 60ft. Quote Link to comment Share on other sites More sharing options...
dx4picco Posted April 19 Report Share Posted April 19 you don't need PID for this, just an aux output used as PWM. you want to increase the frequency or the duty? Quote Link to comment Share on other sites More sharing options...
Speshi Racing Posted April 19 Author Report Share Posted April 19 Thing both at a point. To start with increasing frequency after that DC Quote Link to comment Share on other sites More sharing options...

Adamw Posted April 20 Report Share Posted April 20 A NOS solenoid would typicaly be done using a GP PWM. A basic example below. The solenoid is active when TPS is above 80% and MAP is above 200Kpa and there are no limiters active. The PWM table you can set up however you like. Use a 4D fuel table to add extra fuel when the NOS is active. Speshi Racing 1 Quote Link to comment Share on other sites More sharing options...
