What output out of xfi should i use for weldon pump controller?

[KevinB]

Have a Weldon pump controller that has a "race" setting and is triggered from 12 volts. I want to come off the xfi in the car and trigger it with either rpm or boost. What is the best output to use?
Thanks.

maybe check aux 2 output?
inputs are tps and kpa(map)?

By the time the boost comes up its usually too late. I would use tps/rpm output 1, max 2 amp rating but a relay is about 400MA your good to go.
