Default J&S Ultra Safeguard tuning...

Hello everyone,

I posted this up at another forum, but thought you could help as well. A bit of a read....so thanks!

Oh, no need to tell me about stand-alones like Hondata, etc...I know they work very well, but I'm sentimental and sticking with my current setup.

__________________________________________________ ______________

I had my Ultra Safeguard Ver. 2 installed about 5 years back when I upgraded my JRSC to 8psi. I didn't have the restrictor installed in the inlet hose to my FMU when they dyno-tuned everything; so everything was tuned as best as possible with very rich pressure settings.
I've since reinstalled the restrictor valve, was able to properly dial down my fp settings, but have trouble understanding how to use all the settings on the Safeguard. I've already done archived searches everywhere so I know all about the individual features: 20 or 10 degree control range; Retard All or Individaul; Programmed RPM/Vacuum controlled retard; Boost Start point; Boost Retard rate (0 to 2 degrees); MAP Limiter with adjustment to TP signal. I know what these controls do individaully, up to a certain point, but don't fully understand enough to set everything up collectively to eliminate tip-in at the vacuum/boost transition point.

With the restrictor in, fuel pressures are not only 'in the ballpark', they're pretty much on point (within 1psi +/- corrections). I just need help understanding how to properly set the Safeguard.

Here are the stats (as much as I can think of right now):

JRSC 8psi pulley (10 psi at the gauge)
RC 310's
26psi (34psi static) @ idle
68psi (38psi static) WOT
Stock timing
Around 3:1 rise rate

Current J&S setup:

10 degree retard range (Switch 1 down)
Retard all cylinders (Switch 2 up)
Sensitivity knob turned mid-point (can't tell if it's picking up noise or it's tip-in)
RPM retard @ 6 degrees max. (Controlled by RPM or vacuum between 2500 - 5000 rpms)...This is the one I have the most trouble understanding!
MAP Limiter set at the stock MAP signal (just where the 'Adjust' LED lights up)...
function supposed to help WOT by limiting TPS signal(?), but am I suppose to
turn clockwise or CCW?
Boost Retard set at 1.25 degree per psi. w/ Boost Retard Start Point @ 5 psi.

Currently still getting detonation (or is it noise?) just after 0 vacuum as well as around 5000 rpms under load (boost)...

That's all I can think of...any insights? TIA!!
