Tom,
Lb7's when converted to DSP5 always had DSP Staging available in the code.
They also have a DSP output which I used in my 2002 to control teh N20 when I ran it.
Both worked great on my 2002, my DSP output had a RED LED wired into the N20 in series so when the N20 solenoid relay grounded it lit the LED so I knew when the N20 was being activated.
Ross wrote that into the code probably 8 years ago and back in 2006-2007 I used it a lot on many of my customers builds to turn on lift pumps, etc.
Its not too difficult to set it up.

If only it actually worked on LLY's.
