I believe the bottom picture shows the peak and hold waveform?

Cool, that's great information, thanks. I had been leaning towards a fixed opening with longer time to close, now I can set it for an earlier opening. It's not just a random pwm module, it's automotive specific and has many setup options to suit many applications. I have the English version of the manual if you like to have a look? This is just a temporary setup for now. I fully intend on installing a link next year. I'm just trying to learn more about the fuel delivery system and diesel tuning in general. I'm an industrial instrumentation and Control systems technician, so I have a good grasp on electronics, Its the diesel pump part that is new to me.

My plan is to use the ssr to switch the spill valve to 0v, controled by a link ecu that will replace the oem ecu. I've been told by link that any of the ecu's can perform pulse wave modulation. I'll be using a basic engine control pulse wave modulator until I make the upgrade to link. I just want to do sufficient research before I upgrade. Its my first diesel engine.

I'm looking at intercepting the blue section between 7 and E6. I'm going to take the original pulse width and extend it as required. Why will a SSR not be compatible?
-
Yeah I've done a bit more research and more thorough reading and gone ahead and ordered a Crydon SSR and a diode. I'm modifying the pulse to the spill valve relay, just as the oem computer did. It just seems easier. I haven't thought of cutting it out and directly controlling the spill valve to be honest. I guess it could be done to simplify the circuit. It's a Toyota Surf kzn185 1kz-te.

Hi Does anyone have crydon product specs/model numbers and diode specs for this? I'm looking at modulation of a spill valve relay for a diesel pump off a Toyota Surf 1kz-te. Should pull around 12A. Thanks
