Direct injection - how to set high pressure pump control parameters

Hi everyone.

Do you have any idea how to set control parameters for DI pump in motec m142 or any book/site where I can learn it ? I can't get stable fuel pressure. What I'm not sure is pump timing as engine we use is 5 cyl DAZA and pump is on reduction drive.

This unfortunately is quite specialised and you need to have the parameters accurate if you want any hope of good control. I'd recommend reaching out to MoTeC and see if they have already characterised your particular pump.
