Who tunes with base fuel pres and doesnt use rising rate? Is it easier to tune? Im running 1250cc inj and i can kind of see advantages to both sides? Maybe starting at 42psi and just leaving it there....
Discuss.

The purpose of ignition advance is to account for the lag time following spark ignition for combustion pressure to peak at 15 degrees AFTER TOP DEAD CENTER. A little fyi !
useing the rising rate lets you have more pulse width and more resalution (control) at lower rpms, its almost like having a variable size fuel injector (not realy but it explains it)
sometimes it is hard to get large injectors to idle, but with a RR FPR you get idle and full flow (have your cake and eat it)
