Roush Stage 2 BAP, Details?

[TooSoonJunior]

I am looking over the wiring for the Roush Stage 2 boost a pump, and I noticed there is no throttle or boost input for the ramp rate of the voltage. Does this mean it is simply on full all the time?

Bump anyone?

Are you asking about the Phase 2 wiring? Stage 2 is the suspension and body kits.

I don't know anything about the Roush BAP, but I just installed the VMP Plug and Play BAP. It has only the adapter the plugs in line with the FDMM Harness and a ground wire. It has no boost reference or throttle reference.

The instructions say that the tuner needs to adjust the flow rate flow rate at which the pump switches to high speed. It is supposed to be changed from .80 lb/min to 3 lb/min for supercharged cars.

I am going to confirm with Lund on my new SC tune that they have it set that way.

I have the VMP fuel pump booster as well. Lund told me to get the booster, another IAT2 harness, and a 170 degree thermostat. Installed them all, did the datalogging with them, now I'm hauling a** and happy as a pig in the mud.

Awesome guys thanks, I see the settings in the tune.

For reference this is what I purchased:

I am pretty sure the Roush BAP is only on at WOT so there is no voltage ramp up. It's either on or off.

Enquiring minds want to know.

FYI I am staring at a Roush phase 2 tune and Full on Threshold is set to 0.80lb/min

Strange...

EDIT: what I do see changed Phase 1 versus Phase 2 is the Inferred Rail Pressure is basically flat lined in the phase 2, with little drop off until fuel flow hits nearly 7lb/min. That looks like the main change.

The ECU switches the voltage to ground more rapidly or slowly (duty cycle) dependent upon demand (pressure feedback from the rail sensor). Now for the kicker: Re-read the above paragraph: “… http://kennebell.net/tech/fuel-tech/boost-a-pump-theory-of-operation-explained/
May someone know which wire control raush BAP from ECU brown or yellow ?
