    September 23, 2019. Hello People. Is there a way to program the boost retard start time, or is it only by psi?

    Default Programmable 7 Ignition 7531

    September 23, 2019. Hello People. The Ignition is a Programmable 7 – 7531 Box. The ignition is powering a boat engine and there are no gears to shift, straight to max RPM and max boost occurs at throttle hit. The launch delay is set for 5600 RPM @ .5 seconds the full tilt, max RPM set @ 8500. I’m trying to keep a 38° BTDC for 3.5 second, then enabled boost map set by the plot curve. In other words, control the boost with time delay then psi. Hope this helps, Willis
