In G4+ you need to go to the pin that you want to use and set the function there.  So example below for ign 8.  I have used 2 conditions, both must be true for the sec fuel pump to activate.  The first condition is Ign 5 must be ON - this is your main fuel pump so having this condition will shut off the sec pump in the event of an accident or similar.  2nd condition is MAP >120kpa, so basically as soon as you start to spool it switches on.  Its better to switch it on "too early" as you will always get erratic AFR when the 2nd pump kicks in so best to have this happen at lower load.

True points, thanks mate. The two 460s is on the little too much side, I prefer that as a safety net than relying on a single and getting stuck somewhere in the event of a pump failure
Ive already invested in the radium set up  I don't think I want to play with the fueling set up again for a while unless the fuel temp get a bit excessive with the two pumps That being the case, a good friend of mine has developed a really nice billet surge that I'm interested in should i need to visit the fueling again
